How do you recharge a Gel Battery? (Regular Battery charger does not work)

(1990 Toyota Celica)
Note: The care is an 1985 model, but the options above only allow selection of model years back to 1990.
Since battery contains gel instead of electrolytes, a regular charger won't work. Is there a special type of charger for this? If so, what is it and it's estimated cost? Thanks!!

I am surprised that the charger won't work, because the gel is still an electrolyte. I have charged them before at a shop that sold gel cell batteries as well as conventional type. Have you tried jump starting your car then seeing if the alternator will charge it? Possibly there is an internal short in your gel cell battery and that is is why the charger keeps clicking off. I have never been that sold on them, because they cost so much more than a regular battery. They are good for marine applications, where the battery gets deep cycled and is subjected to lots of moisture, but for a normal car, I don't see the upside vs the extra cost.

Thanks for you quick reply! This is a battery my son bought for his car, but he almost never drives it so the battery sat too long. My understanding is that gel batteries have to be recharged at a lower voltage than regular batteries and that charging too high/fast will damage/overheat them, however, I don't know if a special charger must be bought for this. My mechanic says he can not charge it because he doesn't have a special charger for it. If it does need a special charger, I would either have to buy one, or find another place near me that has the needed charging equipment. I just hate to give up on such an expensive battery. Thanks!
