HEINE BETA 4 NT Rechargeable Handle

Rechargeable handle complete with lithium-ion battery and BETA4 NT lower module High-quality metal construction for strength and durability. Exclusive automatic connector with lock. No friction between metal parts that could cause wear, ensuring reliable fixation of instrument heads throughout the entire service life. Deep discharge protection: built-in safety system protects the battery from complete discharge, extending its lifespan and saving costs. Brightness adjustment: rheostat for stepless brightness control with power level indicator. Lithium-ion technology: no “memory effect.” The handle can be recharged at any time, regardless of the current charge level or battery condition. Extended operating time: about 6 weeks of operation on a single charge when using LED instruments. Fast charging. Slightly textured handle surface ensures a secure grip, while remaining easy to clean and disinfect. Charge status indicator in the lower module: lights orange when the battery needs recharging. In BETA4 USB handles, the indicator flashes green during charging and lights continuously once the battery is fully charged. Ready-to-use function: handles switch on and off automatically when placed in the charging device. Set the desired brightness level once, and the setting is retained every time the handle is switched on. This also prevents battery damage and premature lamp burnout if the instrument is accidentally left on. Not compatible with the NT 300 table charger and earlier models.
