I have a nearly brand new group 27 deep cycle battery. The boat that I just bought needs a cranking battery. The deep cycle, according to the label has many more CCA than the minimum amount that 115 Yamaha calls for according to the owners manual. It also has a longer reserve than called for.
So I'm not a batteryologist. Is there some reason that a DC battery should not be used as a cranking battery, which will be charged by the boat motor?
Put a good charge on it and run it.
If you are not comfortable with that, you could give that battery to me! :)
Sure, there is a difference in design and purpose, but it will work out just fine.
I hope not...I used my last one for 6 or 7 years. I now have a dual purpose for cranking.
I hope not, either .... since I'm using a Everstart Marine Group 24 to start my 90hp Merc 2strk, and have been for the last 5yrs. Most times I don't run the big motor a "whole lot" in a days fishing, but when put on the charger it's either already charged back up or only takes a few minutes until it's at full charge. The charger is a MinnKota onboard w/10amps per lead.Quote:

I run deep cycles on my ski boat for years with zero issues. Need to change my cranking battery because of age and it will be deep cycle also.
I ran a deep cycle on my tracker because I had a anchormate tied into it. They are called a dual purpose because they will do both
Thanks for all the replies! Feel comfortable running it now that y'all shared your experiences.
sinkermaker, this one isn't labelled as a dual purpose like many are, it's a straight up deep cycle trolling battery.
My DC cranking battery is 9 years old, sticker says '08.
I reckon if it was going to do harm, I would know about it by now.
Here's what the "know it all internet" says about that :Quote:

deep-cycle batteries can be used for engine starting but starting batteries should not be used for deep-cycle applications. A deep-cycle battery may have less cranking amps per pound than a starting battery, but in most cases a deep-cycle battery is still more than adequate for the purpose of starting an engine.
My lawn mower has more horsepower than my outboards(s).
Have you thought about putting a prop on your mower? rotflQuote:
