GHU 63Wh Upgraded Power 0A36317 67+ Battery Compatible with Lenovo ThinkPad x220t, x230t X220 Tablet Fast Charge, Lasts Longer Than 3 Hours, Over 500 Charge Cycles Full 5800mAh Capacity

So far so good. The battery fits perfectly and matches the original battery pack size and shape. I had it go through several power-up/power-down cycles of the battery and it is giving me about 2 to 2.5 hrs. of usage time when I have the battery selection set to the second position from the left inside the battery settings under Windows 10. Good value to keep my X220 Tablet (Intel 7 with 6GB of memory) working for few more yrs.

Update 5 September 20237 hours now. Battery was new, with only one cycle charge. Very good results, super solid.------------I was getting ~2 hours with an old battery. This one is giving me ~6 hours after the first charge. Much better but not as good as my original battery when new.I will perform a battery calibration and report back.X220, SSD, 60% brightness , wifi on, bluetooth off, Linux Mint.

Battery died within a weak after properly charging and discharging as instructed. Also gave an error on my thinkpad x220t a few times, has to unplug and plug back in.

Manufacturing date was a a couple of years prior, so 95% is pretty darn good.

dose the trick

I charged the battery for twelve hours. Next day I let it discharge all the way. The day after i had six hours of power during moderate use like sending and reading a lot of messages, browsing the Internet, playing some videos, etc. The laptop is heavier now, but it's worth it.

I've had this battery for over a week now and it consistently lasts about 12 hours on a full charge. The laptop is a Lenovo Thinkpad x220 that only gets light use - web browsing, word processing, some light games. Pretty solid battery life for a replacement. Note that this is the extra capacity battery, so it extends a bit from the back of the laptop and makes it a bit heavier.

After 4 cycles of full discharge, the full energy capacity is 97 Wh at a design capacity of 86 Wh. So far this appears to be better than expected. Let's hope it would stay this way for long enough.
