Battery OPTIMA or Deka

I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.

Deka batteries. I’ve turned wrenches for twenty years and they’re the only ones that still consistently test far above their rated capacity when new. I have one that’s 7 years old and just installed one in my other rig last year.

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.

Optima seems to be the only brand of cylindrical Pb batteries for automotive use... pretty much every other automotive Pb battery is prismatic.

That's the first I've seen one fail this way.

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.

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!!!

my Optima Red Top failed after 2 years & 7 months. this is the last time I'll buy one.
