Importance of Battery Maintenance

When it comes to the importance of battery maintenance, understanding the charging process is crucial. By knowing how your battery is charged, you can take steps to prolong its life and prevent unnecessary wear and tear. Most batteries charge in two stages: the bulk charge stage and the absorption charge stage.

During the bulk charge stage, the charger sends a constant, high-powered current to the battery until it reaches a certain voltage. Once it reaches that voltage, the absorption charge stage kicks in, and the charger sends a lower voltage, constant current to the battery until it reaches full capacity. It’s important to note that overcharging can be just as damaging to a battery as undercharging it.

Therefore, it’s always best to use a charger that is specifically designed for your battery type and to not leave your battery connected to the charger for extended periods. By understanding the charging process, you can take the necessary steps to keep your battery in good condition for years to come.
