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?
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.
