Owner reviews for battery

I installed an Optima yellow top in my 2023 OBW. Works fine!

Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone

Have a 2020 Touring XT. Battery went bad after 5 years so that was normal. No problems other normal wear and tear, tires and brakes.

2014 Mazda 3 with 322,000 kms, it's doing fine. I'm still on original engine, transmission and starter. I use it almost daily in traffic. The only problem is that the battery is slightly more costly than a standard one, which offsets the miniscule fuel savings you're getting from the system

I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.

My wrx would be parked for long periods and I had optima yellow tops. I liked how hard it cranked, good for e85 cold starts. But wow, after the second one went flat I stop getting them. Bought some random battery and it\u2019s been holding charge no problem.

I can say from my experience if it drops below -20C a level one will only really keep the battery from losing power.

Only problem was when a battery blew and that totalled my last Leaf after 154.000 km (98000miles) .

My only issue is I see my battery range moving down significantly. I'm currently doing calculations to see if the battery will be up for warranty replacement.

My Forester is 2021, already replaced the starter and the battery. The current battery starts to feel weak as well.
