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
