CUES. The use of alternative chargers may cause a safety hazard and/or reduce the life of the
battery.
The battery is designed to protect itself against over-discharge, overcharge and short circuit between
charge terminals. Other batteries may not provide these safety circuits.

controller’s Li-Ion
battery to high temperatures (over 140°F or 60°C) may
activate safety systems and cause a permanent battery failure.
