The OEM battery charger on my boat killed a pair of LA 8-D's that were barely 2 years old, when it was going bad. Even though we only turned it on when we were on the boat.
The replacement Xantrex Truecharger, a smartcharger, babies them along maintaining them 24 - 7 at the dock. I average about 9 years on a battery bank before I change them out. I've got one bank due now. Switched to LA 4-D's many years ago because of the lighter weight.
