I don't have much experience but just bought a used canoe and trolling motor to use for fishing. I bought a Walmart deep-cycle battery (I know - but price is a really big factor for me). Now I need a charger to go with it. Can I get by with their $30 auto battery charger or is there an important enough difference that I should buy their $50 charger that says it is for deep cycle batteries?
Also, I have read that it is important not to drain the battery more than about 50%, or its life is significantly shortened, and that means not draining it below about 10.5 volts. Is it really necessary to take a voltmeter out with me or is there an easy way to ballpark when to turn it off? Thanks.
