What is the self-test light of lead-acid battery

Why self-discharge is important in batteries

Lead acid In addition to the above factors, the self-discharge rate in lead acid batteries is dependent on the battery type and the ambient temperature. AGM and gel-type lead acids have a self-discharge rate of about 4% per month, while less expensive flooded batteries can have self-discharge rates of up to 8% per month.

Can the Lead-acid Battery Compete in Modern Times?

The answer is YES. Lead-acid is the oldest rechargeable battery in existence. Invented by the French physician Gaston Planté in 1859, lead-acid was the first rechargeable battery for commercial use. 150 years later, we still have no cost-effective alternatives for cars, wheelchairs, scooters, golf carts and UPS systems.

Lead-Acid Battery Basics

Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.
