12V UL Certified Batteries

The batteries below are certified to UL1973 standard. This is not an easy task! The biggest benefit of this listing is consistent quality over time. Non-certified batteries can change cells and hardware whenever they please, but not these batteries. Whether you buy these batteries today or in five years, they will have consistent quality standards and third party audits. If you want something you can rely on, you have come to the right place!

No Compromise, Highest Quality:

Epoch V2-T

If you really need to depend on your battery in the middle of the ocean or far from civilization, use these. This companies batteries have had the best hardware from day one. The first versions of this battery had some software issues, but now they have made a unkillable battery. I have cycle tested it, max load tested it and tested all safety features and it works great. One of my friends is running it in his truck as a starter battery (not recommended by the company) and he hasnt killed it yet. This brand also makes golf cart batteries that I have been running in my golf cart daily for five years without a single hiccup.
