In daily use

Installation requires basic soldering skills, as the battery features solder tabs rather than a plug-in connector. Once fitted, the cell delivers consistent power throughout the charge, so your clipper maintains blade speed from the first stroke to the last. The moderate self-discharge rate means the battery holds its charge reasonably well during storage, but it is best to recharge before each use for maximum performance. The operating temperature range of -20°C to 60°C during discharge makes it suitable for use in most indoor environments, while charging should be done between 0°C and 45°C to preserve cycle life.
