12v gell cell charging??
Hi,
I apologize if this might have been covered here before.....
My normal charger that I use for charging my 12v gel cell for my flight box has gone bad. I live in Mexico and things aren't all that easy to replace quickly. Can someone tell me if my Accu-cycle Elite can charge my 12v gell cell??
I understand that LiPoly and lead acid/gell cell charging is a similar type of charging, and many chargers for Li Poly batteries can charge both types, but nothing I have found in my Accu-cycle documentation says that it can.
Does anyone have any info they can share on this subject for me?
Thanks,
AV8TOR

You can use your 12V automotive battery charger as long as you can limit the current to 2 amps or less. This type of charger provides a tapering charge and shouldn't harm your gel cell battery at all. Usually this type of charger has a current indicator. Keep an eye on it - the current will usually drop to a couple hundred mAs after a short time.

Ya know, after I posted, and thought about it a bit more, I realized that a LiPoly charger would have to be good for at least 4 cells to charge a 12v gel cel, and the Accu Cycle is only good to 3 cells. Now I feel dumb for posting....
Sorry.
Guess I'll charge it off my car system with a cigarette plug until I can get a 12v charger again....

not dumb at all....
the only stupid question is the question never asked....
the Elite is a great charger, I like mine, but it does have a few limitations

If you use an automotive battery charger, keep in mind, even with a charge current of only a few hundred milliamps, it won't take a long time to charge a 7 ah battery.

Check out www.rcbatteryclinic.com for some good advice on charging all kinds of batteries. One of his warnings is to not exceed a 0.1C charge rate on gell cells, 700 milliamperes in the case of a 7 amphour battery. It is not wise to charge any type of lead/acid battery at high rates.
