What is an 8V AGM deep cycle battery used for?

It powers equipment wired for 8-volt packs, most commonly golf carts and similar electric gear. It is built to be drained and recharged repeatedly rather than for occasional engine starting.

Does it need water or maintenance?

No. The electrolyte is absorbed in a glass mat, so the battery is sealed and does not need topping up. Keep the terminals clean and charge it with a compatible charger.

Can I use it in a 48V golf cart?

Only if the cart's pack is built from 8V batteries. A 48V pack typically uses six 8V batteries in series; check your cart's voltage and battery count before buying.

How does it compare with a flooded lead-acid battery?

AGM is sealed and spill-resistant and needs no watering, which makes it easier to live with. Flooded batteries are usually cheaper and can tolerate overcharging better, but they require regular maintenance.

How should I charge and store it?

Use a charger rated for 8V AGM batteries and avoid deep discharges when you can. For storage, keep it charged and in a cool, dry place, and recharge it periodically.
