Best Practices for Charging and Discharging Sealed Lead-Acid Batteries ...

AGM batteries are a newer type of sealed lead-acid battery that uses a glass mat to absorb the electrolyte, making them maintenance-free. Gel batteries are similar to AGM batteries but use a gel electrolyte instead of a liquid or absorbed electrolyte. When charging sealed lead-acid batteries, it is essential to use the correct charger.
