Guys, I prefer to ask this to be sure I will not damage anything in my car.

I use only my car to go to the train station and then come back. Is only a 15 minutes drive. So when I start my car I feel that the starter is not kiking strong so I check my sealed battery color eye and it show a color that is discharge (I think the color was white)

I take the car to a battery shop and they hook up there battery tester and confirm that the battery is only discharge and maybe the problem is than I am not driving to much to allow the car to charge the battery.

My car battery is a 55 amp and I was thinking to put a charger or a battery tender during the nights at my home but I think the battery tender is around 2 or 3 ampers, so do this will going to top the battery? Also the battery is sealed, do this is ok to charge it or it need some special way in order that the battery vented the fumes.

Please let me know whats your advise.

THX,

Isaac

15 min is more that enough time to replenish the bat. from the start load. Is their a chance you have a "parasitic" load? Or the Bat. has an internal short. Fully charge the Bat. and do a "load" test? If ok then have a alternator load test accomplished. It could have a couple of shorted diodes which would seriously lower it's output.

Its my undertanding than when the battery is discharged you need firts to charge it will slow charge and then with fast charge.
I think the alternator only output fast charge. So is my battery is discharged do I need to charge it first with slow charge? Do a Battery tender will help me?

THX,

Isaac
