Comparing x270 batteries: Kingsener 3 cell vs a "New Battery"
I'm comparing the following 2 batteries for my x270 thinkpad: which of the 2 can
1. give longer hours of usage (assuming doing the same tasks of editing MS Office files)
2. have more discharge/recharge cycles
3. the new battery did not indicate how many cells (guess more is better): any guess how many cells it has based on 4001-5000mAH?
4. the Kingsener model did not state what's it's mAH: based on 11.4V 2.06Ah/24WH, can anyone derive its mAH?
5. feel free to share any other experiences. I know Kingsener is a good brand

>I suspect both are new so not sure which is meant to be the new battery,
the 4001-5000mAH is named as the "New battery": guess they haven't got a brand name.
I've used OEM batteries for Thinkpad & Dell for a long time: some are just as good as genuine
ones while others (esp in the days more than 9 years ago) will break down in less than 1 month.
Kingsener is a trustworthy brand as I've used a few for my x230 & widely publicised their
2 years warranty

Thanks for the update.
I will only buy genuine battery from the manufacturer.
