TECHNICAL SPECIFICATIONS & LEGACY SUPPORT
Battery Model/Type: 633-27, Nickel-Metal Hydride (NiMH)
Voltage: 10.8V
Capacity: 2100mAh
Energy: 22.68 Watt-hours (Wh)
Dimensions: ~145 x 52 x 19 mm
Condition: 100% Brand New, High-Quality Cells
Why NiMH: Many of these legacy instruments were originally designed for NiMH chemistry. Using the correct type ensures safe charging and proper voltage characteristics.
IMPORTANT NOTES FOR NiMH BATTERIES & LEGACY GEAR
NiMH-Specific Charger Required: MUST be charged using the original equipment charger designed for NiMH batteries. Using a Li-ion charger on a NiMH battery (or vice versa) is dangerous and will damage the battery and potentially the tester.
"Memory Effect" Management: NiMH batteries can develop a "memory" if repeatedly recharged without being fully discharged. For best long-term capacity, occasionally allow the battery to discharge fully during use before recharging.
For Professional Technicians: Intended for use by telecom, field service, and broadcast engineers.
Verify Your Device: With such a wide compatibility list, confirming your specific model is on the list (or uses part #633-27) is crucial.
Proper Disposal: Recycle this NiMH battery at a certified battery recycling center.
