Battery Question??

put battery switches on all batteries.
charge fully after each use then disconnect charger and turn off switches.
your batteries will last longer and you won't burn your garage down.
chargers fail not to mention wasted electricity.

That's not actually right. good chargers charge the battery up to full charge, then shut themselves off of charge and switch to maintenance mode and only come back on when the battery discharges itself, from use or sitting, usually 2v's. A simple way to find out what's happening with your charger and batteries is to take a volt meter and watch what happens when the charger cuts on and off. I've heard a lot of good things about Opitma batteries, but like everything else in marine products, YOU GET WHAT YOU PAY FOR

tell that to my buddy that burned his garage down.
chargers can fail.

Believe it or not my boat trolling battery is from 2007 and it still works good knock on wood have no idea of the brand it was in the boat when I bought it

I second what Zimmy said about the Interstate brand. 5 years and still holding a charge on a 24V setup and they get abused a lot throughout the year. I do check the fluid about twice a year and add when needed. Typically only charge them after a trip but will leave them hooked up in maintenance mode for a week or so at a time when i know i will be fishing a lot. I have a 4 bank Minnkota charger but don't feel comfortable leaving it hooked up for extended periods.
