Product Description

8 Weeks Lead Time.

The Ultra Long Life Battery is comparable to Lithium-Ion in both depth of discharge and cycling capabilities. In fact, the ULL Battery out-competes many similar Li-Ion batteries in longevity even when subjected to the same discharge, temperatures, and partial state of charge abuse.

This means the ULL Battery has a fantastically cheap dollar-per-kWh price over its entire lifetime. Each cent gives users more watts for longer than any other battery type.

The unique chemistry of these batteries resists sulfation for a long lifespan, from 8-12 years depending on use. It’s also lighter weight than many battery types and easier to transport and store, since it can be placed in any side or orientation.

These batteries are up to 99% recyclable and an excellent battery for environmentally-conscious users wanting to minimize the impact of their footprint of their solar array.

The ULL Battery’s effectiveness in extreme temperatures makes it an especially durable and adaptable battery when reliability and survival is vital. It’s especially hardy in cold weather, able to survive -40 C/F, far below the average for any other battery technology on the market.
