Is my new battery safe to use?

[andbis]

Hi guys,

I just received a supposedly new battery for replacement in my MBA from mid 2013.
The new battery has a tiny fracture in one corner of one of the cells.

I am in doubt whether I can safely go ahead and install the new battery, or if this is a "fatal" damage?
Should I just return the battery?

Please see the three attached pictures, and let me know if you need additional photos.

Thanks a lot!!

Where did you get the battery? Who installed the battery?

I just received this battery in the mail today, so it was like this when I unboxed it. It is bought from here:

It just looks like a tear in the plastic cover. If you are concerned, contact the seller and ask for a replacement.

I would not use that battery. It is a tiny tear, but what happens if it begins to leak when the battery gets warmed up during charging, and while you are using it? I don't know if it will ever leak, but why take the chance?

Yes, I think you are right about that. Thanks, I'll contact the seller.

U can examine it if u have some sort of loupe/app to see whether only surface damage, otherwise contact seller. Damaged LIONs can be dangerous.
