Battery Tesla or Exide

VW lists 3 batteries, 1 AGM (68 Ah, Varta) and 2 flooded (72 Ah, Varta and 59 Ah, Exide) that may be used.

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.

This one looks like it’s in very good shape, I’ve seen similar for sale for $200 to $300 but the couple I’ve seen at auction sold for $80 and $110 if my memory is correct. Both where in much worse shape than yours.

I have a ‘21 (Dec 2020) M3 LR AWD w/19”. I’ve put 52K miles on it so far. Generally speaking, I’ve seen very little degradation.

I bought a used 2019 LR in 2020 and my estimated range is 302 miles with 48k miles.

All Teslas lose about 10% of their range in their first year. And then it levels off considerably after that.

installed new Exide EK950 AGM 95AH to replace same model been there 3years. No change, and also former battery checks to be in nearly new condition still with measured 90AH capacity from fully charged to 10,5v 9hours with 10Amp load.

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

Left with exide crap.
