When buying a motorcycle battery (or any battery for that matter) always buy a dry battery and add the acid then trickle charge to a full charge. As soon as you add acid the battery starts to decay so a battery stored with acid in it is decaying on the shelf. The longer it sits the shorter the installed life.

I learned all I need to know about life by killing smart people and eating their brains.
