An alternator is meant to maintain a battery, not charge it. Batteries eventually die. Batteries are a consumable product. No battery will last forever. The goal is to consistently maintain your battery to get the most life out of it. Different chargers. Different capabilities. Under normal conditions, most 12-volt automatic battery chargers will work on an AGM battery. Many newer battery chargers have settings specifically for AGM batteries; some even have separate settings for OPTIMA REDTOP and YELLOWTOP batteries, like the OPTIMA Chargers Digital 1200 12V Performance Battery Charger and Maintainer.
AGM and gel technology differ. Remember that the technology of an AGM battery is not the same as a gel battery, which has its own charging requirements. If your charger offers different modes, select the correct one for your battery. If you use the gel setting to charge an AGM battery, it won't fully charge and, over time, it could actually damage your AGM battery. Under normal starting conditions, an OPTIMA battery should never experience at-rest voltages below 12. Most 12-volt chargers and alternators have no problem recharging an OPTIMA if it has an at-rest voltage of 10.5 or greater. The magic threshold – 10.5 volts. The charging scenario for a deeply discharged AGM battery, one that's dipped below 10.5 volts, may be slightly different. The OPTIMA Digital 1200 can recover batteries that have been discharged as low as 1.25 volts. Other charger tips for recovering a deeply discharged AGM battery can be found in OPTIMA's tech tip, How to Resuscitate a Deeply Discharged AGM Battery.
Hook up the good battery and deeply discharged AGM battery in parallel – positive to positive and negative to negative. Do not have the charger connected to the battery or turned on at this stage.
Now, hook up the good battery to the charger. Turn on the charger. The charger will "see" the voltage of the good battery (hooked up in parallel), and start providing a charge. After the batteries have been hooked up for about an hour, check to see if the AGM battery is slightly warm or hot to the touch. Batteries naturally become warm during charging, but excessive heat may be an indication that there really is something wrong with the battery. Discontinue charging immediately if the battery is hot to the touch. Also discontinue the process if you hear the battery "gassing" — a hissing sound coming from the safety valves. If it's hot or gassing, STOP CHARGING IMMEDIATELY! With your voltage meter, check back often to see if the AGM battery has charged to 10.5 volts or above. This generally takes less than two hours with a 10-amp charger. If it has, disconnect the charger from the wall outlet and remove the good battery from the charger. Now, connect only the deeply discharged AGM battery to the charger. Turn on the charger and continue until the AGM battery reaches a full charge, or until the automatic charger completes the charge process. In most cases, the AGM battery will be recovered.
