DR. BATTERY 01AV429 SB10K97586 Laptop Battery Replacement for Lenovo ThinkPad X1 Carbon 5th Gen 2017 6th Gen 2018 Series 01AV430 01AV431 01AV494 SB10K97588 SB10K97586 SB10K97587 [11.58V / 57Wh]

very well packed, arrived in prefect condition. Installed it today, it works perfectly, very easy to replace battery, took me only 10 mins or so. hope it lasts a long time.Update: after 5 months, the battery suddenly died and my laptop cannot turn on at all- it was working alright in the beginning but soon the battery drained very quickly and broke eventually and cannot charge properly again. Very disappointed.

Saved myself probably £100 by ordering and changing the battery in my laptop myself. which is not as hard as you might think as long as you are ok at DIY.

This battery is super lightweight. It came very well packaged so arrived in perfect condition. Would definitely choose Dr Battery again.
