I posted this on Grizzly Central as well, but I'll bet more people will see it here. The owner's manual says a regular battery charger will ruin the battery on my 700 grizz. It says a constant voltage charger must be used. Does this mean I should not use a Battery Tender (float charger)? Because a dead battery on a 700 means your stuck out in the woods I wanted to keep my Grizz on a float charger when it's not in use. Will it ruin the battery instead?
