Battery OEM Toyota or Bosch

My neighbor bought a Prius 15 years ago,whoever they came out, the dealer told him it would cost $5000 for a new battery replacement. It lasted until 2024, it cost $1500 to have new battery put in,aftermarket of course

See alot of "battery replacement cost" blah blah. 1) I have had 4 hybrid work cars (3 Camry and 1 Prius) All driven to 150k or more miles without battery issue. 2) Battery is warrantied by Toyota for 10 yrs unlimited miles 3) If you drive car alot the battery will last along time. If it sits 5 days week and you dont drive alot the battery has a small chance to be bad in 10 yrs. 10 YEARS and that like worst case if sits and not driven combined with being outside in really hot or really cold or both (Northeast). I've never seen it though in 4 cars.

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.

My 2006 Prius's original battery went to 150,000 miles before needing replacement.

I have put 50k+ miles on my 09 Highlander Hybrid in the last 2 years. It charges to 76% and provides 27-30mpg depending on conditions. I love it.

I have a 10+ year old Prius C that had a 100k-mile warranty on the battery. It failed at 108k and cost $4k to replace. It's at 230k miles now, and I expect to have to replace it again (but who knows?)

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

I bought a Bosch battery from a respected online company in the UK. The only change I made was uprating from a 100Ah Varta I think the original was to a 110Ah Bosch S5 015 as I thought more storage would help as the car ages and things are naturally a bit more susceptible to failure. Battery lasted 3 years until about January/Feb 2024 when a cold snap hit and the battery just failed to hold a charge overnight.

I bought these both for the same exact car but both the box and product appear very different, and the bottom set ended up being ridden with parasitic drain!
