Battery help

Gentlemen
Looking for some help in selecting a battery for my motor. I just had the electric start installed in it and want to choose the best that I can put in it. I would like it to be a light model that will still pack a punch. I am using it for a 2016 E-tec 25.
Thanks for the help....John
 
I just got the cheapest L/G battery at Wally World and it started the 25 Evinrude all season. My25 doesn't have a charging system and I never had to pull start. I got a second battery just like the first to run the lights and access. Just letting you know what worked for me. Good Luck, lets see what other guys did.

If money is no object look at a lithium ion battery. This one from Bikemaster is 625 CCA in a 6 lb battery. It's designed to fit a newer Harley touring bike. The original Harley battery it replaces is about 26 lbs and only 390 CCA. Expensive but if you want light with a punch this is it.

Do they make that battery in a 650cca? That is what my motor is calling for. I like the fact it weighs only 6lbs. Just need to start the motor and run my bow and stern lights as well

My motor will be able to charge the battery as well. The dealer said to go with the higher CCA so it doesn't cook the battery when charging.
 
JMac,

Before investing in a lithium battery, you may want to do some research. It is my belief that Lithium batteries required a different charging profile/cycle/ voltage than a lead acid battery. This is fine if charging from 120volt ac with a dedicated charger. This may not work if using the boat motor to recharge the lithium battery. They may NOT play well together.

I don't know this for a fact but it would be worth checking in to before making the investment.
 
It's made for a motorcycle which I would not expect to charge much differently than a boat motor. Worth a call though, especially at the price you'll be paying.
 
WOW, Sticker shock!!!
I got 5 years out of a lawn tractor battery on my old Nissan 18hp electric start, at about 1/6th the price.
Just sayin'...
 
I'm not sure if they make a bigger CCA one or not. They are definitely powerful, they really make a big inch Harley spin compared to the OEM battery. Is the spec on your in Cold Cranking Amps or Marine Cranking Amps? The difference is CCA rating is at 0?F and MCA is at 32?F.

Dave, you're right it definitely wouldn't hurt to make a call to the battery manufacturer to be safe. These are built to go in a Harley so the charging system is very similar to an outboard system. Just a stator and a voltage regulator.

Yep, me too. I'll bet I started using a lawnmower battery for my outboard around 2000. One of my motor and one for my lights, bilge, and depth finder.
 
This is my problem. With adding the electric start it added about 20lbs to my motor which now went from roughly 150lbs to 170lbs. Now also factor in that I am by no means a small guy(310lbs) so thats why I'm looking for the lightest powerful battery that I can get. This is all in a 12ft Roy boat. I will be checking on the lithium battery. I like the fact that it weighs 6lbs. If I had to go to about 20lbs that would be ok I guess. Does anyone know the lifespan of the lithium battery?....John
 
Evenrude recommends that the lithium batteries not be used with their products. Thanks for all your help guys. Guess it back to looking at led filled ones
