One battery, which one to use?

[benyshep2]

I have a 14' boat w/70 HP outboard that has just one group 27 battery. The accessories used are fishfinder and sometimes a the am/fm. The bilge and lights are rarely used. I need advice on what type of marine battery to replace it with, deep cycle or starting? Seems like either would suffice...<br /><br />Thanks in advance!

Dual purpose would probably be best. If you plan on running the fishfinder and the am/fm all day you may want a 2 battery setup.

You want a dual purpose just like brian already suggested.

Personaly I,d go with a deep cycle....your only starting a 70 hp outboard, and won't need all that many amps. A group 27 deep-cycle should have more than enough ccr"s, will last a lot longer, and give you more reserve capacity. Just my opinion.<br /><br /> Jim

I would also go with a Deep cycle battery. Your 70Hp motor porbably does not require any more current than a trolling motor to start. Group 27 deep cycle you can usually get some great deals on.
