Battery OPTIMA or Deka

I found my first optima red top. It was dead when I found it. I just happened to have an agm battery charger/restorer. It took three days of sitting on the machine reconditioning, and then a day or so of charging afterwards. It held a charge forever. It was made in 05 or something like that, and it ran great until this year. I have since replaced it with a new one, and it works great as well.

I have an optima red top 34/78. Its incredible. Been almost 3 years in and no matter how much I throw at it on the trails I dont get dead cells. The individual gel cells are less perceptible to shake damage from rough terrain.

I’ve got yellow top optima. Hasn’t failed me yet :)

I put that same Optima in 6 years ago (to the month!). Mines still fine knock on wood

Red optima battery on my 93 integra 10 yrs old still starts.

FWIW, my post is the top one, I did not go with an OEM battery after reading through other threads where users had issues finding one in stock and instead went with the Optima YellowTop that was recommended on their site. I have had zero issues.

I recently switched to an Optima Red Top 35 Series which has 720 CCA.

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.

Optimas are garbage. Mine didn't survive a 3 month work assignment. The battery was less than 2 years old, and fully charged when I left. Dead when I came back. Blew up like a football when I tried to charge it.

Optima batteries are garbage.
