I like everything, the quality is good, the price is acceptable.

There are no papers in the kit - no booklet, no warranty card (albeit not filled out). Which is a little weird. It is impossible to determine the date of manufacture: I made a request using the code on the hotline, but have not received a response yet. Some pros: The battery came, 12.86V showed a multimeter, without load. Connected to the UPS, charged, not tested yet. Cons: The first time the order was canceled by the store after 5(!) days. Without explaning the reason.
