Certified Refurbished 12V Battery

Giving batteries a second chance.

This is a factory-refurbished Ohmmu battery, sold at a significant discount off the price of a new unit.

Most refurbished stock isn't what people picture. These are open-box units, lightly used customer returns, and batteries with cosmetic imperfections, like a scuffed case, a dented corner, a scratch from shipping. The blemishes are on the outside. What's inside has to earn its way back onto the shelf.

Every refurbished battery is fully inspected and tested by our technicians before it's listed. We check capacity and voltage, cycle life, verify cell balance and BMS function, and confirm the terminals, case, and seals are sound. Anything that doesn't meet our standard for a healthy, fully functional battery is pulled and recycled, not resold. If a unit passes, it performs like a new one.

Backed by a full 1-year warranty — the same coverage and the same support, at a fraction of the cost.
