Collection: Batteries

Marine batteries in this category split into two distinct use cases, and matching the right one to your application matters more than any single spec. ACR Electronics supplies compact lithium primary and rechargeable cells designed for their own safety and signaling devices, so if you run ACR emergency gear, check your device model against the RB16V or LB15V before ordering. Pro-Guide covers the heavier-duty side with two lines built for trolling motors and onboard power: the Signature Series in more compact Group 24 and 8D footprints, and the Alpha Series in taller Group 31 housings for higher-capacity installations.

Before choosing a Pro-Guide battery, confirm three things: voltage, amp-hour rating, and physical group size. Trolling motors run on 12V, 24V, or 36V systems, and Pro-Guide Alpha batteries are available in all three, plus a 16V option that suits specific high-efficiency motor setups. Amp-hour ratings range from 24AH up to 235AH or 300AH, which directly determines how long you stay on the water between charges. The Signature Series also includes a dedicated starting battery variant if your setup needs separate cranking and house power. All products ship as authorized dealer stock with full manufacturer warranty.
