Re: favourite marine battery
The 6volt batteries sold at costco and BJ's are identical the trojan t-105's I just replaced. they were $80 each at costco.
more importantly, you need a good charger.
Iota engineering make good smart chargers, I think the 4 stage, (4 being an equalization once a month) 55amp was under $250 and its a beast.
Unfortunately, the BJ's in my area stopped selling batteries and tires. This was shopped out to an outside company that during the few years they were here had a really bad reputation and attitude toward BJ's customers. I sincerely hope they'll soon go back to selling tires and batteries again like they did prior to the outside company deal. Their prices have always been the best deal around and we always shop there for groceries and lots of other necessities.
