Lead acid vehicle batteries that are never fully recharged can also suffer from acid stratification. This is where the acidic part of the electrolyte becomes …

BU-410: Charging at High and Low Temperatures

Older battery technologies, such as lead acid and NiCd, have higher charging tolerances than newer systems, such as Li-ion. This allows them to charge below freezing at a reduced charge C-rate. When it comes to cold-charging NiCd is hardier than NiMH. Lead acid is also tolerant, but Li-ion needs special care.

Lead-Acid Batteries: Examples and Uses

A lead-acid battery consists of lead plates, lead oxide, and a sulfuric acid and water solution called electrolyte. The plates are placed in the electrolyte, and when a chemical reaction is initiated, a current flows from the lead oxide to the lead plates. This creates an electrical charge that can be used to power various devices.
