Unfortunately, very poor battery quality. Have 4 piece of it, the capacity is only 800-1000mAh. Also, the max. Amperage severely limited by the PCB circuit and is far below the Panasonic cells. With my torch I can with these batteries, the maximum luminous intensity do not use, because then every time the PCB-protection circuit shuts down the battery.
