Battery Tesla or Bosch

just replaced 4 year old battery in my 2010 Wagon. It was not really a rocket science but it was nice to have a write up nonetheless. The biggest issue for me was to figure out group size for my battery: supposedly both 47 and 48 work but I wanted to get an exact model. After some online research and hard measurements it was clear my current battery was group size 48. Went with Bosch from Pep Boys for 108 (with tax and after 30% coupon). Despite the car being without the battery for 8+ hours, I had no issues with codes, errors, etc. The only thing I needed to adjust was the time.

If you have a PepBoys nearby, they have a Bosch that fits.

I have recently had both batteries replaced and the garage I use recommends Bosch as they have a 6 year ' no quibble ' (unlike VW) warranty . They are to the same spec as the Varta batteries and the right one is a 62ah normal lead acid type .

Dude save your money and chance battery yourself. I disconnected battery million times before and all i needed to do is "relearning window position". I bought Bosch group size 48 battery from Pepboys. It fits like glove and has 3 year warranty.

Alright so i picked up a bosch 750 cca battery and threw that in her on another -10 F day, cycled the glow plugs once and she fired up like it was a mid summer day. Hasnt given me any trouble since and its been nothing but cold here.

I'm using a Bosch Group 48 battery (it is 26 months old now) from Pep-boys. Their testing machine result says 'good battery' The guy at the store said, it was as good as a new one.

At one time Bosch batteries had a terrible reputation but they now have their quality control back on track.

Some BOSCH batteries used on VW cars last around 2 years or a bit more but cost appropriately.

2019 model 3 SR with 10% loss based on full charge at 52k miles.

A month ago I bought a 2022 M3P with 7k miles, was at 310 estimated fully charged, now 280 all of a sudden at 10k miles.
