One of the reasons for this thread , I got tired of reading how terrible the Exide battery was. I always plugged into a battery tender . Yearly removed the battery to clean and top up with tap water . ( no I didn't purchase distilled ) .I clean and top up all my batteries .They all last a long time.I also have a Sears Diehard( truck/ute) battery that is 15 years old . Never let a battery losely flop around.I speculate most battery problems are self induced from abuse and neglete.
