One thing to point out for some of you guys that live in areas that have real 4 seasons or extreme heat or cold ones will be detrimental to the batteries. That may be why some are getting shorter battery life.

Just replaced my battery about 3.5yrs. Starter was turning over slowly before replacement. Had battery tender on most of time when bike was not in use. Got a Big Crank EXT 30L from Battery Mart we'll see how she does.

I replace after 4 seasons regardless. Cheap enough to not worry about $. Live where extreme climate change, unheated storage, battery tender winter only. Every battery I've pulled out load tested fine .
09 replaced last week. Original battery wasn't completely gone but was very weak even on a tender. Went on a 400+ mile ride Saturday with the new battery and felt confident that the battery wouldn't be a problem. It wasn't but the weather didn't always cooperate.
