Group 24, 65 Ah, 650 MCA, 120 Res. Min., 10.75"L x 6.75"W x 9.88"H, 39lb. from WEST MARINE
If your engine runs frequently, and your electrical demands at anchor are light, dual-purpose batteries are an effective and economical choice. The result is batteries that deliver plenty of marine starting power while still being able to handle moderate deep-cycle loads. SeaVolt® Dual-Purpose batteries can last through 200+ deep cycles (more than other brands advertising so-called “Deep-Cycle” or “Marine and RV” batteries) and still provide plenty of cranking power. Available at stores only.

SeaGel Battery Group 6 Volt, 180 Ah, 6V, 585 CCA, 850 MCA from WEST MARINE
Versatile and maintenance-free for increased installation options We recommend these batteries without hesitation. They’re remarkably resistant to damage from deep discharges and extended storage. They can even be immersed without leaks, spills or other damage. Once charged, their low self-discharge rate allows the batteries to sit unattended an entire winter without significant power loss. Gel batteries charge at lower voltages than deep cycle or AGM, so smart regulation is advised.
