Baofeng BF-888S Battery Capacity

I opened up a BF-888S battery today to reuse the case and in the process I noticed something interesting. Note the label on the outside of the case that indicates the battery capacity is 1500mAh:

However, once the internal battery is exposed, it’s clearly labeled as a 1000mAh battery:

Apparently Baofeng thinks that adding a plastic case increases capacity by 50%.
