Replacement Battery for Fluke Test Instruments

This Cameron Sino BP120MH battery replaces the original power pack in Fluke 123, 123S, 43, 43B and Scopemeter 120 models running firmware below V2. It delivers 4.8 volts and 3000 milliamp hours capacity with a fully decoded chip that communicates like the factory unit. The pack measures 88.16 by 43.77 by 22.42 millimetres and weighs 221.6 grams.

Nickel-Zinc Chemistry Limits

Nickel-zinc cells operate at 4.8 volts nominal, higher than nickel-metal-hydride alternatives, so the instrument must be designed for this voltage. The chemistry does not suffer from memory effect, but it requires a charger programmed for the correct termination voltage. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are built into the pack to protect both the cells and the analyser.

Capacity and Runtime Headroom

At 14.40 watt-hours the pack powers a typical power-quality analyser or scopemeter through extended field sessions. Runtime falls when the analyser drives its backlight, acquisition memory or communication modules continuously. The battery reaches peak capacity after two or three full charge-discharge cycles. It is not suited for instruments that require a different voltage, form factor or higher watt-hour rating.

Questions about this item

Which Fluke model numbers does the BP120MH 3000mAh 4.8V NiZn battery replace?

The BP120MH replaces Fluke 123 (firmware below V2), 123S (firmware below V2), 43 Power Quality Analyzer, 43B Power Quality Analyzer and Scopemeter 120 when the original part number is B11483 or BP120.

What runtime does the 3000mAh 14.40Wh capacity deliver in a Fluke analyzer?

The 3000mAh 14.40Wh pack powers compatible Fluke scopes and analyzers at 4.8V; actual run time depends on the instrument's current draw and measurement mode.

Does the nickel-zinc chemistry require a specific charger interface or voltage limit?

The battery includes a decoded chip that matches the original Fluke charging circuit; use only the Fluke-approved charger to maintain the 4.8V nominal voltage and protection features.
