Fake or genuine battery?

[umern]

Hi all,
I have a T450 and recently purchased a spare (external) battery 24wh / 68 battery. It was advertised as genuine Lenovo and it certainly looks genuine. The label is absolutely identical - fonts, spelling etc are a perfect match.

The serial number is missing however and I also notice some very minor differences in the physical aspects:
1) the sides of the battery are subtly different - as shown in the attached pictures.
2) there is a slight indentation just below the recycle logo on the new spare battery - whereas my original battery is complete flat in the same location.

Can a few people please compare with their (same) battery and let me know which it compares to? The batteries are labelled in the photos.
Many thanks.

Its probably legit. Its probably a different manufactuer under licence from Lenovo. Its like how both chicony and NMB make lenovo keyboards but they feel slightly different.

Thanks.
I can understand the difference on the side of the casing, but the indentation concerns me.
I ran Lenovo settings and it reported a barcode and Sanyo battery type, 24wh capacity etc - so not sure how meaningful that is in terms of confirming its a genuine battery....

Could just be a manufacturing defect that happens time to time.

You seem pretty concerned so Ill go home and check my X240 battery against yours and see.

seems legit, either a different battery (contract) manufacturer or the same vendor but over the time with slight adjustment in terms of product improvement/ECN's, 'real' fakes looking much worse, I think you are safe ...

What exactly do you mean by "Lenovo settings"? If it's power manager, then you can look at the "manufacture date" and "first used date". If it's a fake (or nonOEM), those usually don't match up. Also, does it charge and discharge just fine?

Not necessarily true. I got a fake 90Wh T430 battery from China and it looked like the real deal. The only thing that was off was a little bit of the label peeling off.

I figure of they put that much effort into a clone battery, it probably wont blow up in your face.

Thanks for all the replies.
Was away from home for most of the weekend - I have let it discharge and charge once so far and the discharge / charge times seemed normal....
Fingers crossed - I am an leaning towards genuine.
Cheers.

The Windows 10 app - 'Lenovo Settings' can be installed from the Windows store - seems to be the replacement for Lenovo Power Manager.
