Which battery do I get?

[epoh tog]

Please help....acquired a new used boat that needs a new battery. Appears they were using a car battery but I would like to replace it with a marine type battery. I have a 225 v6 Johnson engine that I believe is a 1989 model. Will be using the battery to run accessories and starting the engine. Thanks for any assistance you can provide.

Re: Which battery do I get?

I'm on my fourth happy year with a MAXX-29 Deep Cycle, Dual Purpose Marine Battery. It is rated at 875 MCA and 675 CCA. The RC on the MAXX-29 is 205 minutes. The warranty can't be beat.

I have found nothing that competes for near the price.

The battery that was on it was a 24mx - 850 CCA - 135RC.....how does that compare to the maxx-29. I see the cca is less on the maxx-29 and I do not know what the MCA stands for...or what the RC even stands for.

MCA = Marine Cranking Amps. RC = Reserve Capacity. Just buy the largest capacity marine starting battery you have room for. You cannot have too much capacity -- only too little.

Once you look at the batteries and the prices it will make sense. Dual purpose marine deep cycle will support the accessories and can stand repeated deep recharging that starting batteries cannot.

Actually the trojan 27 is 1050 MCA - Marine Cranking Amps:

Thanks for all the help.....I will be looking at dual purpose marine batteries with the most MCA's I can get for a decent price. Thanks again! 8)
