Lead Acid Batteries

SunnyCal maintains a few select lead acid batteries.  The primary application for which lead acid batteries are well suited is bulk storage, where routine maintenance is available, and low cost is a primary concern.

Big warning to lead acid battery users:  

Do not undersize your battery bank!

If you  undersize your battery or solar array, your battery life will be very dissappointing.  This is the most common cause of early battery failure.
