- Is this battery good for an RV house battery?
- Yes. It is a deep-cycle AGM, so it is made for running lights, fans and pumps over hours and recharging, which is the house-battery job. It is not the right pick for engine starting.
- Can it be mounted on its side?
- AGM batteries are sealed and do not spill liquid acid, so they are commonly mounted in positions a flooded battery cannot take. Keep the terminals protected and follow the maker's mounting guidance.
- How does it compare with a 100Ah deep-cycle battery?
- It stores less energy than a 100Ah unit, so it runs loads for a shorter time between charges. In exchange it is smaller and lighter, which helps in tight compartments.
- What charger does it need?
- Use a charger with an AGM or sealed lead-acid setting that limits voltage to the battery's spec. A standard flooded-battery charger can overcharge it and shorten its life.
- What is in the box?
- The battery itself with P terminals. Cables, terminal covers and chargers are usually sold separately, so check what you already have before installing.
- How long does it last?
- Life depends on depth of discharge and charging habits. Treated well and kept charged, a deep-cycle AGM typically gives several years of service before capacity drops noticeably.
- Where is the Duracell Ultra 12V 80AH Deep Cycle AGM Sealed Lead Acid SLA Battery with P Terminals cheapest?
