Battery OPTIMA or Bosch

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

Why on earth would you pay $600 for battery + terminal. I bought recently a BOSCH AGM for $235 and installed it for free by myself after watching a tutorial on youtube.

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.

if you have a costco membership they sell the bosch batteries for a bit more but theyre amazing. 4 year warranty too

I had a Red Top Optima battery, but it’s so dead that even my NOCO AGM charger won’t recognize or charge it.

The optimas (red top) I got in 2019 are still going. They are not the best though just better than liquid.

Those Optima Red, Yellow and Blue tops used to be the cat's ass 20 years ago, but quality has fallen off big time in recent years

My experience: Stay away from Bosch.

I've had a couple of issues with my BMW 5-series, I found Bosch batteries don't last as long as they should. I changed them twice in the span of 3 years or so, each time resetting the battery management system with the correct capacity. I changed it to a Deka Intimidator and I'm much happier with it.
