For the money you cant beat them. I have two that I got early this year and they run great. My brother got some back in 2002 and has never had a problem with them. They have kept a good charge and so on and so on. Just my 2 cents.
ditto on the walmart everstarts.that's all i've used and the price is right.60-70 bucks.i also run a 40# minnkota.
i don't maintain them like i should,but my last one was purchased over 2 years ago,and still doing good.i have another abused one that's 4 years old and though it won't last as long,it still gives me few hours of run time.
