Battery OPTIMA or Deka

Had a yellow optima that went 10 years and it started to slow a bit. Replaced the yellow with a red 6 years ago and it’s still fine.

I use oem bc I get discounted price else I’d use optima, bc I personally on my cars with optimas have never had a problem and oldest is coming up on 9 years

I went to the store and traded the core of my perfectly "good" DieHard Gold (~18 mos old) and spent $400 on an Optima Yellow Top. The difference was immediate. Interior lights were brighter, mirrors functioned normally, no 'system off' garbage, truck opened and closed without hesitation. It starts strong and fast. With the temperature dropping, the peace of mind has been 100% worth the price. I even put the portable jump starter back in the garage. It worked.

Deka. Solid battery.

I bought a red top optimum for my 2019 forester sport. Have had it in for almost 2 years without issue thus far.

My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

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

Optima batteries suck as of the parent company’s sale about 10 years ago. Dead battery rate tripled in our fleet of cop cars (used for driving instruction).

Think my optima red top is about to give out, it's draining down overnight in the cold

I used an Optima, never again.
