Batteries: Flooded Lead Acid

Flooded lead acid batteries have the longest track record in solar electric use and are still used in the majority of stand-alone alternative energy systems. They have the longest life and the least cost per amp-hour of any of the choices. However the other side of the coin is, in order to enjoy these advantages, they require regular maintenance in the form of watering, equalizing charges and keeping the top and terminals clean. Some examples of flooded lead-acid batteries used in solar and wind electric systems are 6 volt golf-cart batteries, 6 volt L-16's and 2 volt industrial cells for large systems.

Please Note: Lead-acid battery prices have been fluctuating frequently due to the changing cost of lead. We do our best to reflect current prices on the site; however they are subject to change.
