I found recently when I checked charging data, from 5/4 to 5/11, my full charge range increased a bit, not too much, but still fine, during that period, cuz I noticed my cell balance is not quite good, so I charged a lot with " cell balancing mode" which is 5A, now I am wondering if slow charging does help to balance cells so that bms up battery charging limitation maybe.

my 8-year battery warranty is coming to an end soon (got less than 5,000 miles left on the clock). Honestly, I’m stressing out a bit about battery failure after the warranty drops.

I’ve been trying to do some homework on how to properly check the pack's health before the deadline, but I wanted to get some advice from anyone who has gone through this.

From what I've read, running the official Battery Health Test in Service Mode is the go-to, but a lot of people say it only gives you an average score and might completely miss things like cell imbalance.

For those of you who kept your cars past the warranty or managed to get a replacement near the end, would love to hear your experiences or any tips! Thanks!
