Battery OPTIMA or OEM Mercedes

I have an Optima Red Top in my 1990 Cabriolet. I have been very happy with it. It is probably about 7 years old at this time and I have never had a problem with it. Otherwise, I would REC a DEKA branded battery. IMHO, "cheap" batteries are not worth the relatively small ammount of money saved.

I'm on my third battery and was thinking about upgrading it to something more reliable, like an Optima.

When I was running two amps 2 12s eight speakers inside head unit capacitor and a built motor I use the yellow top with good success

Your alternator probably just shit the bed. Was on its last of its life then the added \"stress\" of a stereo system made it kill itself.

Anyway I know people talk a lot of crap about them but I use Optima batteries in anything that can fit them. Mainly because I have a bunch of cars and many of them sit around. Its nice to know that if the battery dies I can condition and recharge it and get back to normal and not worry.

I am entertaining an Optima Yellow Top this time. It's $339, for reference, and I have a feeling it will outlast/outperform the OEM.

I bought an optima just because it and it's custom hold down looked cool. Unfortunately I let it sit with no tender for over a year and it discharged almost completely. I've been able to nurse it back and it is functioning at this time, but not sure it will hold a charge. We will see. I'm happy with it otherwise.

It literally is of 0 benefit and in fact they have shown to have a shorter lifetime in these applications.

Optimas quality fell off hard when they moved manufacturing to Mexico. They've been riding on their previous reputation ever since.

I had the same problem. My car was brand new too but was sitting for a bit before it was sold to me. I brought it in to get charged a few times but the message was still coming up and I was definitely driving it enough. Eventually they just changed the battery under warranty.
