The original battery was replaced under warranty by Honda right after I got the car, about 2 years old. The Honda replacement battery lasted about 3 years. Replaced with a Bumblebee high performance battery that lasted just over 3 years. I rebuilt that battery using sticks from it and from a used similar battery which I nursed along for about 2 years with the help of a grid charger. Eventually I bought a high performance 3 year warranty battery, about 7 months ago.:?: What is the longest anyone in this forum has gone on the original battery pack?
:?: Also, when replacing the battery unit, are there other related components that absolutely must be replaced, too?
