Having connected it and assuming something is wrong on connecting ( user wrongly connected or marked incorrectly) the possibility is that it may be compromised. As it is only a cheap component I would chuck it in the bin and buy another one from a reliable source.
I have used several form Ann/Ann battery and all have been good with no issues, key is though connecting all up correctly.
