Battery OPTIMA or OEM Mercedes

Optima battery. They handle the cold much better.

A lot of people say the Optima is not a good battery anymore, but I continue to have good luck with them.

I use an Optima Yellow Top battery and it made a big difference. The Yellow Top is honestly just good for the car in general.

I’ve got Optima batteries in some of the more “Special” cars.

Yellow top is/was a hybrid cranking/deep cycle battery, once popular for putting big stereo systems in cars because it could handle the discharge cycles of running the system without them engine running.

Ive been using a yellow top for around 5 years in my CRV with no issues

I replaced the battery with an optima battery brand new I assume the high quality battery. If the battery was a problem would fix it but it did not and now I’m back to square one

I purchased one because of my car stereo upgrade, thinking it would be a better choice. Within a few weeks, I noticed that my cranking was slow and labored. It is almost seven months later, and I find myself having to randomly jump-start my car. Note: At first, I was concerned that my audio amps were not turning off properly and checked to confirm that everything was off. I think I may need to go with a different solution now.

Just bought a new G63, same issue!

I went through 2 of them in my Corvette. The last one was making sizzling noises after I needed a jump from a 200 amp battery jumper. The top of the battery was meled,.Not worth the money. Never again!!!
