New replacement battery for Lenovo ThinkPad X220 Tablet. NOT produced by Lenovo. Brand is - HSW. Has very good reviews. Bought from Amazon. Reason for letting go: my ThinkPad is ax220i. As shown from pictures, the battery does not fit as it's for X220 Tablet, not X220i. Had bought it thinking there was no difference. But as you can see from my pictures, the HSW Battery (bigger one), can't fit. Bought for 55sgd, letting go at 40sgd.
