I had a Yellow top optima installed for my subaru around 2015, it lasted until just today - held out well
Bosch batteries in my older bmw lasted around 5 years but I was told it’s recommended to change every 2 years.
Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.
Maybe last year I got a letter from Subaru Canada saying the battery was being recalled and I could get a replacement.
…After I had already replaced it with an Optima Yellow Top.
We have a 2009 Fiesta 1.4 petrol and replaced the battery with a Bosch battery 5 years ago after the same issue. The car does a few short journeys a week so not ideal but there's no signs that the battery is about to go flat.
looking at that reciept seeing Enhanced flooded its even worse, we are a main dealer of Bosch batteries and their EFB rated voltage is 12.6V when not in use not sure for the other big battery brands
New battery fitted and all ok for about 2 months, then same problem. Took new battery out (AGM Bosch S5 A08) and charged it on the bench, left it there overnight. Next morning its reading 12.2v.
Optoma are shit nowadays anyway.
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
