quality control? for replacement batteries and spare parts

Okay no matter how much they promise that if you are unhappy with the purchase it will be done right; I don't like sending things back, I'd rather get a good battery first. When I unpacked the battery, I saw the following. Some kind of sealant, filler? which dried up, cracked and fell out from under the contact (see photo). This is something that shouldn't be present in a new battery. That made me doubt the quality. Returned.

Pros
