I reviewed the pictures in the complaint and it would appear as if a label that Tokibo places on the battery has worn over time and the label that SSCOR places on the battery has also worn over time.
This is to be expected as the batteries are used.
The battery compartment is rather tight - we want to make sure it is not possible for the battery to move around in the battery compartment and as a result, the sticker may wear as the battery is used.
A replacement battery will work the same as the batteries they are currently using.
Best regards
