Reply #2 - 07/09/12 at 15:48:30 I would wonder why you mite think you couldn't,......or how else you would get it charged. Altho, maybe it shouldn't surprise me,....w/ as many false rumors/myths that float around in the battery world.

Reply #5 - 07/09/12 at 19:02:40 Some of the new batteries have a warning against using a charger with a de sulfation mode. Either I read that somewhere or I dreamed it. But it's in my head. And since it's now on the Internet, it must be true.

When I bought the battery the sales guy was all about it, he said it would never leak or anything even if it was upside down. I told him that really didnt matter to me since my battery leaking would be the least of my concerns if I ever found myself upside down on the bike

Also love the fact that you never have to check the acid level, would never go back to an unsealed battery.

A bold statement !
While it is true that AGM has a slower "self discharge" rate than lead acid, only those that get charged (ridden) regularly, need "never" be charged,.........if you are looking to get maximum life from it.
The #1 killer of batteries is not being fully charged 100% of the time, which as we know most all batteries are not.

If a battery (AGM or LA) could stay fully charged all the time, its useful life can/will easily be extended to 8-12 yrs.

This is why any battery that spends its down time on a good maintainer charger (13.2-4v max) can outlast a "normally used" battery 3-5X.

No, not a battery expert, but I have taken an interest in battery longivity many yrs ago, and have proven the above to be true many times.

The Telephone companies have know about this for years. They have even got it down to the best float voltage to keep the batteries on for best life. The SLA batteries they use normally last anywhere from 20 to 30 years in normal service.
