Owner reviews for battery

Mein Tesla Model X hat jetzt 300k km und läuft noch wie am ersten Tag (2018). Batterie noch so bei 83%

UPDATE: i just got my wifes car back from the dealership and it turns out it was the battery for hers. The voltage thats normal for her car is 14.8 volts not 13.4. He said there are 40+ computers and when the voltage is low it causes havoc in the car.

2017 got a new battery in 2023 before winter, didn't have a no start issue but figured it was time. Went with a dealer battery, was only $138ish for the 72ah upgrade and replaced it in their parking lot to get the core charge back.

I had to replace the battery on a 2016 Crosstrek this summer and, in retrospect, missed a bunch of warning signs before it finally wouldn’t start: slow cranking, occasional extra crank needed, flickering dash lights, and generally dim interior lights.

Even though the battery tested fine the problem went when I replaced the battery.

If the battery dropped to 9V it is probably defective.

Drive a 2018 Nissan Rogue, about 80k miles. Have a Duralast Gold battery from Oct 2023, but live in central Texas where I hear batteries don't last as long.

Depends on the car, both highway speeds:

- Our good EV, Ioniq 6: went from 18kWh/100km to about 26kWh/100km.

- Our bad car, EQB: Went from about 26-28kWh/100km to about 29-30kWh.

In the 166 body MB ML/GL, its under the passenger seat, with barely enough room to reach the rear terminal. It's also so far forward that you can barely grab the fuckin thing. Oh, did I mention that it is a group 49 battery.

I just changed them out in a new (to me) Jeep Gladiator. First one was easy. That stupid aux battery required pulling the front right wheel and the splash guard, then dropping the little tray it’s in.
