My wife and I bought a small pontoon boat on year end clearance to take advantage of the beautiful, large reservoir we have access to. It came with an Interstate 1000 CCA marine starting battery. I ordered a Blue Sea Systems battery switch to facilitate and extra battery. Boat has a Yamaha 60hp which is it's maximum rating. Other than starting, and using the stereo while out cruising or at anchor, there shouldn't be much more demand for power. One battery might be all I need but for the cost of the switch and an additional battery, I'd feel a lot better especially if spending a long day out on the water.
My question is, what kind of battery should I get for the backup? Another 1000 CCA marine battery? An automotive deep cycle battery? Or, does it really matter for it's intended purpose. Walmart has a 1000 CCA marine battery for $74.99. A 650 CCA deep cycle automobile battery for not much more. Any ideas or suggestions. Thanks.
