Deep Cycle Battery FAQ
-
What does AGM mean on a deep cycle battery?
Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte absorbs into a fiberglass mat. The plates in an AGM battery may be flat like wet cell lead-acid battery, or they may be wound in a tight spiral.
-
How do I know if my deep cycle battery is AGM?
Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out. On the other hand, the liquid acid batteries have a removable top which is not the case with AGM batteries as they are properly sealed.
-
When should I charge my deep cycle battery?
They should be recharged when they indicate a 50% charge, but never let them get lower than 20% to ensure a long life. Lead-acid batteries, such as deep cycle batteries, run the risk of sulfation if left uncharged for too long.
