My 2015 Leaf has 148k on it and still drives like new. The battery is down to about 85% but this is pretty old lithium tech with very early thermal controls on it.
My EV is 8 this year. I've not noticed a drop in range over that time, but I'll find out when it goes in for its last battery health check before the warranty expires.
I used euro car parts 444770127 which is a mid range bosch battery. Don't remember any issues
Bosch, m-a tinut 8ani. Acum tot bosch de 70/75am luat.
The mechanic I go to gives me Bosch and they last around 2 years if not more. But then they do die within a day when they do.
Bosch - 2.5 years so far,
Varta - 1.3 years before dying
My cargo bike advertises a range of 40-70 miles depending on level of boost. I get up to 40, at the very most, but never more. I use minimum boost only, and usually don’t ride up any major hills. I’ve wonder if this is just grade inflation for marketing or if my Bosch battery was just old/crappy when I got it.
I switched to Bosch after that. that failed after 2.5 years, just under warranty. so it can happen with any company. some batches might have good quality some do not.
Bought a 2025 Rogue Platinum less than 2 weeks ago. So far, on day 4 the car was completely dead in my driveway. Needed the battery replaced.
My experience: Stay away from Bosch.
