deep cycle batteries vs. cranking batteries - The Hull Truth

capt.nick · 03-20-2007, 05:05 PM

Today I went to replace my original deep cycle batteries and the Yamaha tech on duty told me Yamaha was not recommending deep cycles for my 225F Yamaha. He stated it was "straight from Yamaha". He said you need a cranking battery and gave me an 100 CCA batttery. Is this true?

Nick,

Out of the 2004 Yamaha rigging guide page 4-4 under recommended F200-F225 battery specifications.................verbatim(that is a BIG word for me btw) [img]../images/emoticons/biggrin.gif[/img]

CCA Rating(Cold cranking amps) min512

MCA Rating(Marine cranking amps) min 675

RC Minutes(reserve capacity inminutes @ 25 amps) 182

Yamaha recommends a Cranking type battery that can have distilled water added to it cells when necessary. Dual purpose CrankingDeep cycle batteries can be used if they meet the above spec and water can be added to the cells. Do not use maintenance free or Gel Cell batteries since they may not be compatible with Yamaha engines charging system.

Sim,
Thanks for the quick reply and good info. (as usual) Obviously that 100 CCA was a typo. (meant 1000)

Now would that apply to all Yammies? My 2003 OX66 200hp came with two dual purpose Exide Nautilus NC-27's
MCA=730 RC=160, no way to add water. Is this an issue? That's what the dealer installed.

Fish,

Personally I would not use a wet cell battery that I could not properly maintain (water check). But that is just me.......

So AGM's are out of the question?

That is not what I posted.......if I was using a wet cell battery it would be of the type that I could maintain.

I have personally and I also know of several Yamaha owners that have used AGM's with great success and have had no issues. I would not use a Gell cell though.

Well they're going on 4 years old so I'll keep that in mind when I go to replace them, as always Andy, thank you
