Why do some batteries get hot? | Science Questions

Dave - Charging batteries isn''t 100% efficient and similarly, discharging batteries isn''t 100% efficient. The way electronic engineers like to think about it is that the battery has a resistance, so if you draw a current from that battery then you''re pushing that current through a certain resistance and so, it will heat up.

Battery gets hot during charging on bench | BobIsTheOilGuy

Lead acid battery cycles are NOT 100 % efficient, it takes MORE than 10 amps for an hour, for example, to fully charge a 10 amp-HOUR battery. Probably more like 12 to 15 amps for an HOUR. The rest ends up as heat. The accurate test of a storage battery is how many amps it will deliver for an hour... "amp hours".

FAQ: How to protect your battery against the summer heat

As lead acid batteries absorb high heat, chemical activity in the battery accelerates. This reduces service life at a rate of 50% for every 18°F (10°C) increase from 77°F (25°C). If a battery has a design life of six years at 77°F (25°C), and the battery spent its life at 95°F (35°C), then its delivered service life would be three years.
