Although expensive, it’s still cheaper than purchasing separate cranking and deep cycling batteries of the same quality.ĭimensions: 13 x 6.8 x 9.4 inches | Weight: 77.8 pounds AGM batteries are also more resistant to shock and vibration and have a lower self-discharge rate. The battery’s AGM design means that you don’t have to top it up with distilled water or worry about spilled battery acid as you would with traditional wet-cell batteries. Rated to 100Ah, it should deliver 5 amps of current per hour for 20 hours, giving you plenty of time to troll your local lake, river, or ocean without recharging.Ī full recharge takes just four to six hours. It also has impressive deep cycling capability, lasting up to 400 cycles at 80 percent depth of discharge with a reserve capacity of 142 minutes.

There are different types of marine batteries, but the best are generally AGM or absorbed glass mat batteries. Key features to look out for include the battery’s cold-cranking amps or CCA, its reserve capacity, and its amp hours. Alternatively, some marine batteries fulfill both purposes. A deep-cycle battery delivers less energy over a long period and is used to power your trolling motor and/or onboard electronics (like a marine stereo). The former’s sole job is to provide the short, sharp burst of power required to start your inboard or outboard engine. The first step is deciding whether you need a cranking or deep-cycle battery. Choosing the correct marine battery is a difficult task and one that takes into account several factors. Whether you're a bass fishing pro or a scuba diving fanatic, if you have your own boat then a marine battery is right up there on your list of must-have equipment.
