Basic standards for lead-acid batteries

11.5: Batteries

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

The basic chemistry of gas recombination in lead-acid batteries

Oxygen-recombination chemistry has been wedded to traditional lead-acid battery technology to produce so-called sealed, or valve-regulated, lead-acid products. Early attempts to incorporate recombination into lead-acid batteries were unsuccessful because of excessive cost, size, and/or complexity, and none were effectively commercialized. …

Lithium-Ion vs Lead-Acid Batteries Comparison: Which Is Better?

In terms of cycle life, lithium-ion has higher life than lead-acid batteries. If maintained well, the average guranteed lifespan of a basic lead-acid battery is around 1,500 cycles. In comparison, the typical lifespan of a lithium-ion battery is around 5 years or at least 2,000 charging cycles.
