A good battery, the balance seems to be present, but I can't tell from the cells whether they are high-capacity or not; it's not clear from the labeling. But it's been working longer now.

Delivered in 2 weeks. Looks solid. The charge indicator shows in percentage. Upon arrival it showed 68%. There was a plastic cap on the terminals (not shown in the photo) and a holder. Quite heavy (~870g). Didn't disassemble it because I don't want to deal with the seal on one of the screws. Didn't measure the current output, but the tools (wrench, angle grinder, vacuum cleaner) work without any issues. I recommend it for household use.
