The Adventure Series Sodium 12V batteries are built for the places maps don't cover. It's engineered for overlanders, off-road builds, and anyone who needs a battery that simply will not quit — no matter what the terrain, temperature, or conditions throw at it.

Most batteries have a breaking point. Extreme cold kills cranking power and desert heat degrades cells. With 1,400 CCAs and an operational range of -40°F to 172°F, this battery was built specifically to eliminate both failure modes — delivering consistent, reliable performance without compromise.

This isn't marketing language. It's the chemistry. Sodium cells handle thermal extremes that push lithium and lead-acid to their limits — making this the most climate-resilient 12V battery available in the H7 and Group 27F form factor.

Key Features

Climate-Proof Chemistry — With an operational temperature of -40°F to 172°F, sodium-ion technology outperforms lithium in extreme temperatures, making it ideal for year-round outdoor use.

1,400+ CCAs — Serious cold cranking amps for reliable engine or equipment starts even in demanding conditions.

Higher Nominal Voltage — Delivers cleaner power for brighter LEDs and better audio performance compared to lead acid without sag.

Eco-Friendly — Longer service life means fewer batteries consumed over time and less material waste.

More Sustainable Materials — Sodium uses abundant, affordable materials with a lower environmental footprint than lithium or lead acid.

App-Compatible Monitoring — Pair with the optional Ancel BM200 Battery Monitor and Ancel BM200 app for real-time state of charge and diagnostics. Available on iOS & Android.

2× the cranking power, a fraction of the cost.

Starting power is measured in CCAs — cold cranking amps. The Adventure Series Sodium delivers up to 2× more CCAs than a comparable lead-acid battery, meaning faster, more reliable starts in any weather.

And when you stack CCAs per dollar against the competition — lithium, AGM, or standard lead-acid — nothing in this form factor comes close to the value the Adventure Series Sodium delivers.
