I'm on the fence about buying a new 3rd-party battery for my Thinkpad T480 as the current external 61 battery is only yielding ~3 hours on normal use (90℅ capacity, so still good given I bought the laptop used) and there's no internal one on mine.
I'm a bit wary of Chinese-branded and other similar no-name batteries as I recall having read an Amazon comment of someone's Thinkpad catching fire because of such a battery, which is why I'm more looking at brands like Green Cell.
So far I found the 01AV424 61+ battery by Green Cell, and even though they only list the "T470, T570, A475, P51S, T25" models it should still work with the T480, right?
Anyone here got experience with their batteries? Or maybe I should look for another brand?
Thanks!
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.
