Everything is fine, there are only minor drawbacks.

The seller saves a lot on packaging, it is so minimal that there is simply nowhere else to go. The battery came in a simple plastic bag, the contacts stuck out, the protective cap on the plus flew off, it can easily "short" during transportation. For this one star. However, there are no complaints about the battery itself, the charge test showed 13.8 volts.
