Battery OPTIMA or OEM Audi

I run yellowtops in my car and truck and the truck is going on 5 years now and still kicking.

I have have good luck bringing sulfated Optimas to my local Interstate Battery. They’ve brought several back from the dead for me and they went on to last a very long time.

I got a red top optima, put the subaru battery blanket on it. Good down to -10f.

Optima Red Top has been treating me well.

I like AGM batteries. Using optimas now, whenever these finally die I'll try another brand. 4 years in now and I can't notice any loss of capacity yet. They work amazing when it is like 0 degrees F, too.

If you do need one, optima is pretty good but expensive.????

The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.

Have two red tops in my 05 GMC. Sneaky suspicion one is bad. They were new when I got the truck six years ago.

Went to start truck after sitting five days and it was dead. Meter showed 12.1 and it charged in an hour which is very fast. Truck would turn over but not run. Checked charge again, primary at 12.4 and secondary at 12.7. Swapped places and truck starts, runs, all accessories work now.

Stay away from optima batteries unless your car specifies an AGM battery because they can be very problematic.

my 2009 had an optima and it only lasted 2 years
