In this video we help you troubleshoot your vehicle when it's not starting.

All Models | Battery is Reading 0.0V with MultiMeter

Problem:

Battery is reading 0.0V with MultiMeter.

Solution:

Our batteries have a built-in BMS (Battery Management System) which has the ability to 'disconnect' internally in the event of a dangerous situation, this includes OVER voltage, OVER temperature and OVER current (shorting of terminals included).

In these scenarios a RESET is needed.

To reset place battery in a cool safe location without anything connected to it for 5 minutes. Then apply 12.0V - 14.8V to terminals. After a few minutes remove the voltage from terminals and check battery voltage again, it should be restored.

All Models (Bluetooth-Enabled) | Safeguarding Your 12V Battery While Parked and Unplugged for an Extended Period

When parking and leaving an electric or hybrid vehicle unplugged and unused for extended periods, it's important to consider and safeguard the health of your 12V battery (as well as the high-voltage battery pack, although that is out of the scope of this article).

Guidance varies from car to car, according to the specific make and model of your vehicle, so it's important to refer to the vehicle manufacturer's recommendations before proceeding.

Important Note: Tesla EVs can be particularly demanding of their high-voltage and low-voltage batteries, even when not in use, and Tesla generally recommends leaving your vehicle plugged in during extended periods of inactivity to avoid potential issues.

If keeping your EV plugged in isn't possible, there are many online resources available with strategies, best practices, and recommendations for settings which can be turned off to minimize battery usage while parked and unplugged/unused for long periods of time.

After reviewing your vehicle manufacturer's recommendations, if you wish to safeguard your 12V battery from phantom drain and other possible issues, one option available to you with our Bluetooth-enabled 12V batteries is to toggle off the “Discharging” option in the Ohmmu Energy app.

This will essentially disconnect the 12V battery from the vehicle and preserve its state of charge, especially if the high voltage battery is low and can not maintain the 12V battery while the vehicle is unplugged, not being driven, stuck on a software update, etc.

Please follow the below steps to perform this procedure.

Disabling the Discharging Function on your Bluetooth-enabled 12V Battery (and then Re-Enabling Upon Return)
  1. Make sure vehicle is parked and in a safe location to perform procedure.
  2. In the Ohmmu Energy App > Dashboard, you can turn off both the “Charging” and “Discharging” toggle switches, entering the default security code “999000” for both.

Ohmmu Energy App - Toggle Charging Off

  1. The battery's discharge functionality is now turned off, preventing power to be drawn from the 12V battery to the vehicle.
  2. IMPORTANT: When you've returned and are ready to drive the vehicle again, re-enable the “Discharging” feature prior to driving the vehicle, as shown below:

IMPORTANT: The “Charging” and “Discharging” toggle switches should be kept on at all times while the 12V battery is installed in your vehicle, except for temporary instances where you are performing a reset procedure such as this. Please note the “Charging” and “Discharging” toggle switches instruct the Battery Management System (BMS) to either ‘allow’ or 'block' charging and discharging of the battery, and should be used with caution.

Tesla | All Models | Access Tesla Service Mode

In this video we show you how to access Service Mode in your Tesla (some models may differ slightly) and how to change the battery type when swapping out your old battery for a new Ohmmu 12V battery.

Tesla | All Models | Identifying Low Voltage Battery System (12V vs 15.5V)

Beginning in Mid-2021, Tesla began converting the low voltage battery system in its vehicles to utilize a 15.5V 6.9Ah Li-Ion battery. Tesla models with this revised low voltage system are NOT compatible with Ohmmu 12V LiFePO4 batteries.

12V Low Voltage Battery Versions by Model / Year — Compatible with Ohmmu

  • Tesla Model S: 2012 – 2021.5
  • Tesla Model 3: 2017 – 2022.3
  • Tesla Model X: 2016 – 2021
  • Tesla Model Y: 2020 – 2022.3

15.5V Low Voltage Battery Versions by Model / Year — NOT compatible with Ohmmu

  • Tesla Model S: June 2021 and later models
  • Tesla Model 3: Spring 2022 and later models
  • Tesla Model X: 2022 and later models
  • Tesla Model Y: Spring 2022 and later models

If you're unsure which low voltage battery system is in your vehicle, please follow the steps below:

  1. Using your vehicle's MCU, open the “Controls Menu” by tapping on the car icon in the lower left corner.
  2. Next, tap on the “Software” tab, and then click on “Additional vehicle information”.
  3. Confirm if there's a line stating “Low voltage battery type: Lithium-Ion”. If yes, then your vehicle has the 15.5V low voltage system and is NOT compatible with an Ohmmu 12V battery.
  4. If you don't see information regarding the low voltage battery type, confirm if there's a line stating “Infotainment Processor: AMD Ryzen”. If yes, then your vehicle has the 15.5V low voltage system and is NOT compatible with an Ohmmu 12V battery.
  5. If the infotainment processor listed says either “Infotainment Processor: NVIDIA Tegra” or “Infotainment Processor: Intel Atom”, then your vehicle has the 12V low voltage battery system and IS compatible with an Ohmmu 12V battery.
Tesla | All Models | "Replace 12V Battery Soon" Alert

This alert usually self-clears after replacing the 12V battery, however in some cases it does not (depending on certain conditions of the vehicle). If your error did not self-clear upon install then you need to do a 'deep reset' which involves resetting the DC/DC converter.

The procedure depends on the vehicle, but the goal is to fully power-down the vehicle so the DC/DC converter resets itself and recognizes the new battery.

Alert pops up after a recent software update

Please perform the following reset for your model vehicle to clear this alert. If the alert returns shortly after doing a hard reset (same software version), please email support@ohmmu.com with a photograph of the list of alert codes by going to the 'Service' menu and then tapping on ‘Notifications.’

Explanation: Unfortunately, Tesla has had a longstanding issue with their OEM lead-acid 12V batteries being short-lived and at times dying on customers with little to no warning, often resulting in people being stranded, locked out of their vehicles, in need of a tow, etc. -- this may have even been a primary factor as to why you purchased an Ohmmu 12V LiFePO4 battery.

In response to this ongoing issue, Tesla recently began releasing software updates which monitor and run tests on the 12V battery in an attempt to provide customers with an advanced warning of a battery's failure. In some instances, these tests unfortunately get confused by our battery's higher capabilities and returns with a false error in response - usually this occurs after a recent software update.

We are currently tracking the issue as there have been intermittent reports coming in. Fortunately, the vast majority of these alerts have been resolved by performing a deep reset with no further issue (see procedure instructions below) and we will continue to monitor and investigate this issue.

Please Note: in the vast majority of these cases, this warning alert is erroneous and your Ohmmu 12V battery is very likely completely healthy and operating as it should. Our batteries are built with a very stable lithium iron phosphate (LiFePO4) chemistry and have a long-lasting and reliable battery life, so if you are experiencing this error it is very likely a false alarm.

Tesla | Model 3 / Y (Bluetooth-Enabled) | Reset Procedure via Ohmmu Energy App

(Est. Time to Complete: 5–10 mins)

Connect Ohmmu App to 12V Battery (Bluetooth-Enabled Versions Only)

  • Download and install the Ohmmu Energy App from the App Store for iOS or Google Play for Android.
  • Open Ohmmu Energy App and verify your 12V battery is connected. If not, open the device list and connect to your 12V battery.
  • Your battery needs to be Bluetooth-enabled to connect with the Ohmmu Energy App. Look for the Bluetooth-enabled symbol on your battery or verify the model number on your order receipt ends with -B or -BH for compatibility.
  • Follow the reset procedure below.

12V Battery Reset Procedure - 'Low Voltage Battery' Errors

  • Make sure vehicle is parked and in a safe location to perform reset procedure.
  • IMPORTANT: Roll window down and leave the driver's door open for the ENTIRE PROCEDURE (Model 3: Also leave passenger side rear door open).
  • Open frunk.
  • In the Ohmmu Energy App > Dashboard, turn off both the “Charging” and “Discharging” toggle switches, entering the default security code “999000” for both. See below:

Ohmmu Energy App - Toggle Charging Off

  • Then, on your vehicle: locate and Disconnect High Voltage (HV) using the disconnect method for your vehicle - see below:

Model 3: Located under passenger side rear seat (to access, slide seat lock tab toward center driver side to unlatch, then lift seat cushion up, remove black foam block, and locate grey plug underneath)

Model 3 HV location

Disconnect HV: Unlock Grey/black header by pinching top and rotating locking arm downwards, then pull up to disconnect

Model 3 HV disconnect

Model Y: Located in Frunk on passenger side above wheel well (red/black connector near First Responder Loop w/ orange tag)

Model Y HV location

Disconnect HV: Slide red lock open, then squeeze end of plug while pulling apart to disconnect

Model Y HV disconnect

  • [Situation-Dependent]: In the event that your 12V battery is dead, or if it has a total voltage below 13.0V, it will be necessary to manually recharge the 12V battery above 13.2V before proceeding. To do so, we recommend disconnecting the 12V battery from the vehicle (doesn't need to be removed from the vehicle, but can be) and connecting it to this battery charger or an equivalent 12V LiFePO4 battery charger until it's voltage is above 13.2V — this will take ~5 hours if charging from a dead battery state (i.e. 12.5V). The following (or any lead acid battery or trickle charger) would also work for EV batteries but may take much longer to charge (~24 hours) depending on amperage https://a.co/9EEPl6D
  • Reconnect High Voltage (HV) using the reconnect method for your vehicle - see below:

Model 3: Reconnect Grey/black header by pushing firmly back into place and then rotate locking arm upwards into locked position

Model 3 HV reconnect

Model Y: Push together connectors and slide red lock into closed position

Model Y HV reconnect

  • Wait 10–20 seconds
  • In the Ohmmu Energy App > Dashboard, turn on both the “Charging” and “Discharging” toggle switches, entering the default security code “999000” for both again. See below:

Ohmmu Energy App - Toggle Charging On

  • After your vehicle reboots, the app should indicate that your vehicle is now recharging your 12V battery. This will confirm that your vehicle is now managing the 12V battery charge/discharge cycles again as it should.
  • If any alerts remain on your Tesla's MCU screen, they should clear after driving the vehicle for a short period.

IMPORTANT: The “Charging” and “Discharging” toggle switches should be kept on at all times while the 12V battery is installed in your vehicle, except for temporary instances where you are performing a reset procedure such as this. Please note the “Charging” and “Discharging” toggle switches instruct the Battery Management System (BMS) to either ‘allow’ or 'block' charging and discharging of the battery, and should be used with caution.

For example, if you had “Charging” toggled off and “Discharging” toggled on, your battery wouldn't allow itself to be recharged, while still discharging energy to provide 12V power to your vehicle. These settings would cause the battery to eventually drain completely and no longer be able to power the vehicle's 12V systems (dead battery and vehicle). Please be mindful when toggling these switches in the app, as they may leave your battery in a state where it is blocking all charging or discharging energy and prevent it from functioning correctly in your vehicle.

As technical reference, when “Charging” is toggled on, the battery remains internally connected when a current of 0.0A or greater is present (positive current going into the battery), however when it is disabled, the BMS will react to any current greater than 0.0A and internally disconnect the battery to prevent it from charging its cells. Similarly, when “Discharging” is enabled, the BMS allows the battery to discharge energy to external current draws, however when it is disabled, the BMS will block the battery from discharging energy and won't provide any external power.

(Est. Time to Complete: 5–10 mins)

Connect Ohmmu App to 12V Battery (Bluetooth-Enabled Versions Only)

  • Download and install the Ohmmu Energy App from the App Store for iOS or Google Play for Android.
  • Open Ohmmu Energy App and verify your 12V battery is connected. If not, open the device list and connect to your 12V battery.
  • Your battery needs to be Bluetooth-enabled to connect with the Ohmmu Energy App. Look for the Bluetooth-enabled symbol on your battery or verify the model number on your order receipt ends with -B or -BH for compatibility.
  • Follow the reset procedure below.

12V Battery Reset Procedure - 'Low Voltage Battery' Errors

  • Make sure vehicle is parked and in a safe location to perform reset procedure.
  • IMPORTANT: Roll driver's door window down and leave the door open for the ENTIRE PROCEDURE.
  • Open frunk
  • In the Ohmmu Energy App > Dashboard, turn off both the “Charging” and “Discharging” toggle switches, entering the default security code “999000” for both. See below:

Ohmmu Energy App - Toggle Charging Off

  • Disconnect the High Voltage (HV) system via First Responder Loop w/ orange tag, located in Frunk on passenger side above wheel well, using the disconnect method below:

Model S (All Versions: April 2016 – May 2021): https://youtu.be/zDi5to4WhA4?t=627

Model S (All Versions: 2015 – March 2016, and Dual Motor 2014+): https://youtu.be/tqx3kG0TAQs?t=236

Model S (All Single Motor Versions, 2012 – 2015): https://youtu.be/aYShHfOsNVk?t=230

  • [Situation-Dependent]: In the event that your 12V battery is dead, or if it has an extremely low state of charge (SOC), it will be necessary to manually recharge the 12V battery above 13.2V before proceeding. To do so, we recommend disconnecting the 12V battery from the vehicle (doesn't need to be removed, but can be) and connecting it to this battery charger or an equivalent 12V LiFePO4 battery charger until it's voltage is above 13.2V — this will take ~5 hours if charging from a dead battery state (i.e. 12.5V).
  • Reconnect First Responder Loop to re-engage High Voltage (HV) system.
  • Wait 10–20 seconds
  • In the Ohmmu Energy App > Dashboard, turn on both the “Charging” and “Discharging” toggle switches, entering the default security code “999000” for both again. See below:

Ohmmu Energy App - Toggle Charging On

  • After your vehicle reboots, the app should indicate that your vehicle is now recharging your 12V battery. This will confirm that your vehicle is now managing the 12V battery charge/discharge cycles again as it should.
  • If any alerts remain on your Tesla's MCU screen, they should clear after driving the vehicle for a short period.

IMPORTANT: The “Charging” and “Discharging” toggle switches should be kept on at all times while the 12V battery is installed in your vehicle, except for temporary instances where you are performing a reset procedure such as this. Please note the “Charging” and “Discharging” toggle switches instruct the Battery Management System (BMS) to either ‘allow’ or 'block' charging and discharging of the battery, and should be used with caution.

Tesla | All Models | Hard Reset Procedures

For our latest smart lithium batteries with bluetooth connectivity (SKUs ending in -B or -BH), you may perform a reset via our app:

Tesla Model S

  1. Open drivers door, roll down drivers window and open frunk
  2. “Power off” vehicle via MCU Safety & Security screen
  3. Disconnect First Responders Loop
  4. Disconnect 12V battery (leave installed, just disconnect the negative terminal) - need 10mm wrench for this.
  5. Wait 1-30 seconds max
  6. Reconnect First Responders Loop
  7. Reconnect 12V battery, then wait 2 minutes
  8. Step on brake pedal and wait for vehicle to reboot

Tesla Model 3

See Tesla | Model 3 / Y | "Schedule service to replace low voltage battery" Error

Tesla Model X

  1. Open drivers door, roll down drivers window and open frunk
  2. “Power off” vehicle via MCU Safety & Security screen
  3. Disconnect First Responders Loop — our installation video shows the process here: Disconnect First Responders Loop
  4. Disconnect 12V battery (leave installed, just disconnect the negative terminal) - need 10mm wrench for this.
  5. Wait 1-30 seconds max
  6. Reconnect First Responders Loop
  7. Reconnect 12V battery, then wait 2 minutes
  8. Step on brake pedal and wait for vehicle to reboot

Tesla Model Y

See Tesla | Model 3 / Y | "Schedule service to replace low voltage battery" Error

Tesla | Model X | "Unable to Drive: Voltage Supply Too Low" Alert

Problem:

I just replaced my battery and now vehicle says: “unable to drive: voltage supply too low”. After a few minutes of being on, but undriveable, the entire vehicle shuts back down. No clicking noise after reconnecting the 12V power.

Solution:

Your vehicle uses 12V to boot up all of the computers and prepare for power on, however in order to power on and drive the High Voltage battery contactors must engage. Since we aren’t hearing the clicking of contactors after connecting the 12V power on the vehicle we can determine that there is an issue with these contactors coming online. Since your vehicle is showing some signs of 12V power present (screen boot up, headlights flash, horn works, etc) we can be sure we have 12V power, but no High-Voltage power.

There are 2 potential reasons for this:

  1. Failure to resecure the High-Voltage disconnect (Model S and X: red loop that plugs in under hood, Model 3 and Y: grey header that plugs in under passenger side of rear seat). FIX: 1. disconnect 12V battery 2. secure the plug 3. Reconnect 12V battery
  2. Blown contactor fuse. FIX: Fuse F125 which is a 10A “micro2” fuse, check and replace fuse. Fuse can be purchased at any auto parts store.

If fuse was blown, likely reason is that the high-voltage plug wasn’t removed for the install process, please follow the procedures in our battery swap videos to avoid this.

Tesla | Model 3 / Y | "Schedule service to replace low voltage battery" Error

IMPORTANT: If you have a newer Bluetooth-enabled version of our battery, please refer to the following procedure instead: Tesla | Model 3 / Y (Bluetooth-Enabled) | Reset Procedure via Ohmmu Energy App

Support Notice Information

A potential issue has been identified for customers with Tesla Model 3 and Model Y vehicles, running software updates 2021.36.x and later.

Tesla has pushed several new features with their recent updates, which appear to alter the method and extent that the vehicle utilizes its 12V battery. Due to these changes, it is possible that you may receive error alerts for your 12V battery on your Model 3 or Model Y vehicle when it updates to these software versions.

IMPORTANT NOTES:

If you're experiencing error alerts, your battery is most likely healthy and your vehicle will continue to operate (some features may be turned off by Tesla software, such as USB ports and seat heaters).

However, if you receive this error alert and experience any other issues, please contact Ohmmu Support and we will walk you through a reset procedure or assess your situation and provide the necessary assistance.

To clear the error alerts and perform a software update (which may resolve these issues), please follow the RESET & SOFTWARE UPDATE PROCEDURE provided below.

Tesla | Model 3 | Locked out of Vehicle - How to Gain Access to Frunk
Problem:

I'm totally locked out of my Tesla Model 3 - how do I get into the frunk to install my new battery?

Solution:
  • Find the tow bar access point on the drivers side bumper.

Tow bar access point

  • Push upper right corner firmly until the bottom left corner flips outward.

Flip cap outward

  • Pull the cap forward to reveal 2 wires, one with a red tag on it and the other without a red tag. Apply voltage to the wires - you can use a 9V battery or your new 12V battery to do it. Red wire should go to positive terminal and the other wire to negative. Frunk will now pop open on its own.

Frunk release wires

Tesla | Model S (First Gen) | Battery Negative Lug Doesn't Fit

Problem:

Battery Negative lug doesn't seem to fit when battery installed.

Solution:

Remove Negative Terminal Adapter, then mount lug to adapter, then reinstall and rotate lug about 90 degrees from its original installed position.

Model X and Model S: "Schedule service to replace low voltage battery" – GTW_w174 Alert

If you get an alert to replace 12V battery in the Model S or Model X, you can find what the actual alert is by going to the 'Service' menu and then tapping on 'Notifications'. If the active alert is GTW_w174, please find more information below pertaining to that:

The GTW_w174 alert at this point doesn't appear to be related to any performance issues with our batteries and a simple reset has proven effective at clearing it and restoring normal operation*.

The GTW_w174 alert can be easily reset with the following procedure:

  1. Unplug USB devices
  2. In MCU go to service menu and tap 'wheel configuration', then change wheels to a different size and style
  3. Wait for reboot
  4. Repeat and change wheels back to actual size and style.

* You may also try a hard reset, or for bluetooth-enabled battery with Tesla Model X: Reset Procedure via Ohmmu Energy App or Tesla Model S: Reset Procedure via Ohmmu Energy App to clear the alert and allow the vehicle to charge the 12V again.

For our bluetooth-enabled battery, please confirm both Enable Charge and Enable Discharge toggles are in the on position via the Ohmmu app, Apple's XiaoXiangElectric app or Google Play's XiaoXiangElephant app.

In the event the battery is drained/dead, a jump pack (power supply/force/boost mode if available) or another vehicle can jump our batteries to wake it up.

We would recommend connecting battery to this battery charger for 5 hours (above 13.2V).

The following (or any lead acid battery or trickle charger) would also work for EV batteries but may take much longer to charge (~24 hours) depending on amperage https://a.co/9EEPl6D
