Thoughts on Green Cell batteries? (Thinkpad T480)

metiulekm, 4 months ago

As a data point, I have a Green Cell battery in my X220. I have bought the battery on July 24, 2022 and I have been using my X220 regularly but lightly. The battery was marketed as 6600 mAh at 10.8 V. As of writing, the OS reports design capacity of 73.26 Wh and current capacity of 60.6 Wh:

So 82.7% left after 1.5 years, that’s cool I think!

(especially given that they offer only a 12 months warranty)

X220 uses 18650-cells, which are superior. Either he uses it always on charger or the cells are really bad quality.

Nevertheless, has nothing to do with your T480 since it has LiPo batteries, not 18650-celled.

No idea about green cells. I’ve done ok with Dr. Notebook batteries from battdepot.com.

Ifixit sells very repuatble battery replacememts, i have one for my t440p! If ifixit doesnt sell it inland (microcenters brand) batterys work well and i have never had any issues with either.

For how long did you have that battery?

i bought one from ifixt 1 year ago 9cell for my w540 and this Christmas i bought a 6cell, and ive had and used both. the 9 cell gives me 8hours of battery of medium usage, web browsing, word processing and such.

Not Green Cell, but I got a 6 cell replacement from GHU for my T440s workhorse. For the first week, it reported 9+ hours on a charge. Super cool, I thought, I can basically work outside as long as I like. The second week it went down to 2 hours on a full charge. 50USD down the tubes. I’ll pay the premium for OEM batteries from now on. This, of course, was just my experience, but reviews suggest it is a common one. I just thought it would be worth the risk.

The OEM route is tempting me too to be honest but at the same time Lenovo doesn’t make those batteries anymore and those that you’ll buy would have been in their storage for years.
