Take your "fully charged" battery to Advance and get it load tested -- bet it fails.

Or, if that is too much trouble then hook your "fully charged" battery up to your bike and see if it will crank anything -- then immediately check the voltage and report what it dropped down to.    

(you load tested it, Savage style)

Gel cells are funny -- you are showing a most excellent surface charge that reflects your battery charger is over charging the shite out of the gel cell battery.  

What sort of charger do you have, anyway?   You are saying "charger/maintainer" Battery Tenders (maintainers) are no good for charging a dead battery, you can kill them trying to do that.


==============


You did remember to disconnect the battery charger before taking those readings, right?   We are looking for the resting charge state of the battery, not the output of the charging system.

For example, if you had just taken the charger terminals off you could get a very high surface charge voltage that actually reflects the output of the charger -- let it sit overnight and test it and you find a much lower "resting charge state" that reflects what is internal to the battery.

Oldfeller, it seems we think the same way
