I have a red battery light malfunction on a 2003 E-500...Where is the best place to buy a battery?

from the dealer.....

Make sure you replace the correct battery, typically a red light is the aux battery located under the hood.

call roadside assistance. Pay for the part, free installation at your location.

+1...going to the dealer will get you their "bend over w/o lube" labor rate special...good luck.

Is there a trick to getting the battery cover off, I'm having trouble

MB211

This trick works pretty well, certified MB tech does it for you......

I do not know if they do the aux battery though, sign and drive is supposed to be for jump start / battery replacement when car is not starting.

Also, it may not be a bad idea to have the car looked at. You make have additional issues. (i.e battery control module fault). You may even want to check if the campaign for control module flash applies to your vehicle and was performed.

Thanks MB211

It was the aux battery and the trick to getting the top of havc was just "snapping:" the cover from the side back.
