Quick Answer
AGM batteries can be recharged with both solar and AC power, but it's essential to follow proper charging techniques to maintain their lifespan.
Charging AGM Batteries with Solar Power
AGM (Absorbent Glass Mat) batteries can be charged with solar power using a charge controller specifically designed for deep cycle batteries. When using solar power, ensure the charge controller is set to a float charge voltage of 13.5-13.8V for most AGM battery types. This prevents overcharging and ensures the battery is maintained in a healthy state.
Recharging AGM Batteries with AC Power
When recharging AGM batteries with AC power, use a battery charger specifically designed for deep cycle batteries, and set the charger to the recommended absorption charge voltage for your battery type, typically between 14.4-14.8V. It’s essential to follow the manufacturer’s instructions for the charger and the AGM battery to ensure safe and proper charging. A battery conditioner or equalizer can also be used to balance the cells and maintain the battery’s health when recharged with AC power.
Best Practices for Charging AGM Batteries
To extend the lifespan of your AGM batteries, it’s crucial to follow best practices when charging. Always use a battery monitor to track the battery’s state of charge and prevent overcharging. Avoid deep discharging, as this can reduce the battery’s lifespan. When storing AGM batteries, keep them in a cool, dry place with a state of charge between 20-60%. Always follow the manufacturer’s instructions for charging and maintenance.
