AGM batteries require a special charger that is certified to charge AGM's. You can easily kill the battery if you use a regular charger with it.
Yep, same type of battery in my Harley, properly charged up, sounds like I'm getting proper voltage, I know the first day of running with a full charge it will show 14 volts all day long, a few days later it shows 13 running, our running is in the country not the city so the jeep is getting a good run each time.
