This battery has a great capacity and a high degree of consistency in the supply of electricity. Although it is not a flat top battery, but a button-top battery, some devices can not operate it, the sublime positive is just not high enough. So have to find verifiable example, that for example some NiteCore flashlights with this battery will not work (which is by the mechanical reverse voltage protection of the lamps). If the positive pole 2-3 10ths mm higher, the battery could get smooth 5 star because he would be universally applicable. .... Maybe this little undersized by the manufacturer but also extra-willed, so that only the flashlights going well so from their own home? who knows? Otherwise, it is a great battery, which is a great source of power for all devices that allow even at shallow Plus Poland good electrical contacts.
