I'm wanting to upgrade my batteries on my G3 17 footer with a 12 volt trolling system.Does anyone know where i can get the best price for Optima batteries.Any advice on the model numbers and application would be a help too.The website is kind of confusing but i think i need a yellow top for the troller and a blue top for the motor.BTW i have a 70 hp yamaha.I would be grateful for some help.
You'll probably want the blue top for the trolling motor. I run three of those....one for cranking and electronics, the other two wired for 24V. I've never seen them on sale anywhere that I can recall. Check your local auto parts store and see if they can give you a price.
I got mine from [url]http://www.1st-optima-batteries.com/?gclid=CNaS3pSWnKcCFcZw5Qodbmg-cw[/url] with free shipping when Optima had a rebate program
You're upgrading to 12 volt? You sure you're not wanting to upgrade to 24 volt?
I believe he said he was upgrading batteries for a 12 volt system. Two 6 volt batteries (golf cart) run in circuit ( pos. to neg.) will out last any 12 volt battery about 5 to 1 for amp hours.
Optima batteries are made by Johnson Controls....which owns Interstate Batteries. I would check at an Interstate dealer and then check them out online too before you buy them.
Thanks guys i appreciate it.Yes,i already have a 12 volt system,just wanting to put some better batteries in.
I bought my latest Optimas from Amazon.com and saved about fifty dollars on two batteries. I love my Optimas!
You want to get the Blue Top Optimas for Boats. They are made for a marine enviroment. They are vibration resistant which is great for boats where batteries take a pounding in rought water in a boat.
I'd recommend the biggest Bluetop Optima Deep Cycle for the Trolling motor. You want as much reserve Amp Hours as possilbe.
Get the combination starting/deepcycle Blue Top optima for your motor and other accessories.
I've got a Blue Top Optima (dark gray bottom plastic) that I'm still using to start my boat after 8 years. It's still holding a good charge but I will probably have to replace it this year or next year. I keep it fully charged up after every trip. It does a lot of sitting in my boat in the garage as I've turned into a fair weather fishermen over the last 3 years. But before that I was out even in Dec fishing all year round from 2003 until 2009 with this Optima Battery. I still have my older Blue Top Optima Trolling Motor's Deep cycle battery that I use for fishing lights and other things. It's still holding a good charge too. And it's about 8 years old.
Other deep cycle batteries that I had that were just regular lead acid type and not AGM would only last me a few years and then they would not fully charge back up.
Also the Optima's Blue tops will charge up mush faster than a regular lead acid battery with lead plates and Sulfuric Acid water. And these Optima when fully charged will hold their charge for nearly a year. Other lead acid batteries won't do that.
The Optima's use more pure lead which make them less resistant to electrons and therefore they take a full charge much faster than regular lead acid batties.
They do cost more and trying to get the best price is a wise decision. Check around and shop for the best price you can find.
I got mine at Autozone but they also sell them at Gander Mountain where I live in Evansville, IN.

I also run the Blue Top D31 Optima's and I can't say enough good things about them. Yes they are costly but look on the internet. I got free shipping on mine. I keep a trickle charger on both and I have no issues.
i run an optima 34 in my nitro , 12 volt , fish every weekend and have had zero problems with it . i was going through an interstate battery every year . bought mine at sams club , just under 200 dollars . more expensive than the other batteries but saved me money in the long run.
