buoymaker Learned a new thing on Walmart batteries,you've seen those month and year stickers on their batteries ?? Bought a new one put it right on the charger,took about 6 amps,came back after a while still 5or6 amps ! I think those are sulfated,now those stickers are cheap !! So returned it,went to the 55 year junkyard bought about a 1 year old battery 40$ took about 6 amps but soon dropped to about an amp. Installed it really whip it over,put on charger came right back up ! So conclude you better check even new ones over for age especially in these hard times.
