X220 very high battery wear on multiple batteries

2018-01-25, 14:54 PM

I have recently gotten an X220 and couldn't be much happier with it, especially considering it's a laptop from 2011. However, I purchased a few new batteries with it, an original 6cell one and two 9 cell ones which are not original units, and these wear down extremely fast; about 40% in half a year approximately. I don't keep them charging when fully charged, nor do I run them down to almost 0%, so I am not sure what causes this extremely high wear. 

 

Now I expected the non-original batteries to wear down pretty fast, but not this fast. Could it be that I'm using a 90W adapter? Does this charge on a higher voltage/current which these batteries cannot handle? I've measured the voltage of the adapter, and it runs at 20.5 volts when not connected to the X220, so that seems ok.

 

Any ideas?

Welcome to the Community

The answer is in your post:
"two 9 cell ones which are not original units".

The type of the AC charger (either 65w or 90w) doesn't matter in your case.

> Any ideas?

Replace it for Lenovo genuine battery.

I understand, I have been looking for genuinie Lenovo batteries. However, these don't seem to be on sale in the Netherlands. At the official Lenovo service point, they are not available.

 

Where can I get these batteries?
