The Heine BETA4 NT Rechargeable handle is the next generation in energy management. Thanks to the Lithium-Ion technology with no 'memory effect,' you can charge your handle how you like without having to worry about charge level or battery condition. 

• High capacity - more than double the capacity compared to previous NiMH rechargeable batteries! 
• High-quality metal construction for strength and durability 
• Quick charge - approximately 2 hours to recharge with the NT4 table charger (SKU 3744)
• Charge status indicator light: light pulses from the illuminated charging wells indicating the charging mode. Continuous light indicates that the charging process has been completed. 
• The bottom insert illuminates in orange when the battery needs to be recharged - no more guesswork
