Lead acid is dependable and inexpensive on a cost-per-watt base.Lead acid has a moderate life span, but it is not subject to memory as nickel-based systems are, and the charge retention is best among rechargeable batteries. The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in subzero conditions.
