I'm very careful around batteries, since blowing one up, 35 years ago, about 3' from my left ear. Probably why I have tinnitus now. I'd be even more careful, when the battery is 6" under my crotch.

 

first oil, and now batteries. you're really batting .1000 here. can't wait to hear what your next area of expertise is gonna be

 

No guy, it doesn't matter if it was HD battery acid or any other brand. You don't add acid to an old battery, you add distilled water. You don't add anything to a sealed battery. You just opened up a maintenance free AGM battery, added acid to it, glued the seal back on, and then put it back in your bike. You should seriously consider getting someone else to do every bit of your maintenance, like even adjusting your mirrors.

 

 

I work in the battery industry (UPS batteries) & if you know what your doing you can add acid to a maintenance free AGM battery. In fact in some conditions this is standard in the industry to avoid replacing them prematurely under warranty.

The key is to not completely seal that cap, because it is actually a pressurized one way vent cap, usually calibrated to open (vent) at a set PSI.

So if you get a few more weeks out of it while your waiting on you new one to get here, more power to you - don't listen to all these other mis-informed people.

 

If I'm mis-informed, its only because every technical publication I've read relative to batteries for the past 30 years was wrong. Exactly what department in the Uninterruptable Power Supply battery industry did you say you work in? If it is such a common practice in the industry to add acid to an old maintenance free UPS battery, you shouldn't have too much trouble providing a qualified reference to support your claim.

 

Adding acid to an AGM power sports battery is NOT A STANDARD IN THE INDUSTRY to avoid replacing them under warranty!!! The sealing strip you say is a calibrated vent is FALSE, it is nothing more than a sealing strip that is NOT designed to be removed.....Period.


Please get your facts straight as this type of information is very misleading.

 

You got some great service from your battery, If it's the ORG. from 07. I use the battery tender on mine all the time>

 

it's definitely not AGM. AGM has a 1 to 3 PSI pressure relief valve and is sealed. This battery has an clear vent with the typical condensation traps as well as having 6 cell access plugs. The cells are straight forward wet cells.

 

it depends on your hydrometer readings, if the acid specific gravity is weak, you don't want to add water. If the acid specific gravity is very strong, you can add water. as the acid leaves the battery thru the vents, sulfuric acid will accumulate on terminals and areas around the vents. Adding acid to a battery with a low specific gravity replaces the sulfuric acid .
