BigBattery offers a 10 year manufacturer's defect warranty from the date of purchase. The average lifespan of a BigBattery battery at 100% Depth of Discharge is between 1,000 – 3,000 recharge cycles depending on chemistry or roughly 5 to 10 years with standard use. This warranty does not cover negligence or misuse of the battery or normal wear and tear. If it is deemed that the battery was used improperly, you will be subject to a $150 an hour repair charge plus parts and shipping.

Our batteries are commonly used for RV's, Golf Carts, Wind, Solar, Forklifts, or Off-Grid Power Applications.

All batteries come with free ring terminal cable. If you are connecting your battery to a solar panel you require a inverter or charge controller which are sold separately. Parallel cables, parallel boxes and series cables are also sold separately.

Sizing solar batteries is one of the first steps in designing your off-grid system. The amount of battery storage you need is based on your energy usage. Energy usage is measured in kilowatt hours (kWh) over a period of time. For example: 1,000 watts x 10 hours per day = 10 kWh per day
