Our take on the Duracell Ultra 12V 35AH Deep Cycle Battery with J Terminals

The Duracell Ultra is a sealed lead-acid deep cycle battery rated 12V and 35Ah, built for repeated discharge and recharge rather than engine starting. Its J terminals and spill-proof AGM-style construction suit trolling motors, mobility scooters, UPS backups, and solar or off-grid setups. Against flooded deep cycles it needs no water top-ups and can be mounted in more positions; against lithium rivals it is heavier and shorter-lived per cycle but far less expensive and simpler to charge. Buyers choosing it are usually after a dependable, maintenance-free battery for moderate daily draws.

Questions and answers

Is this battery good for a trolling motor?: Yes. It is a 35Ah deep cycle battery, so it handles the steady draw of a small trolling motor better than a starting battery. Runtime depends on motor thrust and speed; plan on a few hours at low settings.
Can it be used as a car starting battery?: No. Deep cycle batteries are made for slow, repeated discharge, not the high cranking amps a car engine needs. Use it for accessories, backups, or motors instead.
How should I charge it?: Use a 12V smart charger with a lead-acid or AGM setting and keep it topped up after each use. Avoid leaving it discharged, which shortens its life.
Can it be mounted on its side?: The sealed design generally allows side mounting, but keep the terminals up where possible and secure it so it cannot shift. Check your device's manual for any restriction.
How long will it last?: Expect several hundred charge cycles with good care, typically a few years of regular use. Shallow discharges and prompt recharging extend its life.
What is in the box?: The battery itself with J terminals. Terminal hardware and a charger are usually not included, so confirm what your setup needs.
Where is the Duracell Ultra 12V 35AH Deep Cycle Battery with J Terminals cheapest?: At Batteries Plus, for $89.99, as of our latest check.
