battery issues

well this morning when i get in my jeep to go to school i started my jeep and the little message screen said "check battery" so i figured my battery needed to recharge so i kept my system off and just ran the radio cuz i have a switch for the amp. my question is should i take my battery out and recharge it or just not run my system for a few days to let my battery to recharge?

i don't listen to my music a ton when the car is off. my alt i think is 90 amps.

i just don't want to be stranded some place. it takes ten minutes to get to school, then ten minutes home. i heard that it takes like 15 minutes at highway speeds to recharge ur battery from the juice it took to start the car. so another thing i am wondering is if my battery has enough time to recharge? thanks in advance.

How are you recharging it? Are you letting the car sit idle or did you take it out and charge it some other way?

If you have a regular car battery charger, watch the amps on the meter. If the battery is drawing like 4 or 5 amps while charging, you might wanna consider replacing it.

If it draws little to none, the batt is fine just charge it.

This is what I would personally do because you can find out if your battery is gonna die soon.

well the battery charger was set to put in 2 amps. i left it on for a couple of hours and worked just fine. my screen in my jeep doesn't say check battery anymore.
