Frequently Asked Questions
What is an AGM deep-cycle battery?
AGM stands for Absorbent Glass Mat. AGM batteries are sealed, maintenance-free lead-acid batteries designed to provide reliable power through repeated discharge and recharge cycles.
Does an AGM battery require maintenance?
AGM batteries are sealed and do not require adding water. Keep the terminals clean, avoid excessive discharge and recharge the battery promptly after use.
Can I use my existing battery charger?
Use a charger with an AGM-compatible charging profile. Many modern smart chargers support AGM batteries, but the charger's voltage and settings should be verified before use.
Can an AGM battery be used for a trolling motor?
Yes, deep-cycle AGM batteries are commonly used for trolling motors and other marine accessory loads. Choose the battery size and reserve capacity based on the trolling motor and expected runtime.
How should I store an AGM battery?
Fully charge the battery before storage, disconnect it from loads and periodically monitor its state of charge. Recharge it when necessary to prevent prolonged storage in a discharged condition.
