Replacement battery for Fluke analysers

The Estry Ni-MH pack delivers 4.8V and 3000mAh capacity, matching the original BP120 and B11483 specifications. It fits Fluke 43, 43B, 120 power quality analysers and the Fluke 123 Scope Meter running firmware below V2.0. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Steady output during extended measurement sessions

The 14.4Wh energy rating supports long logging runs without the voltage sag seen in lower-capacity cells. Protection circuitry maintains stable delivery across the discharge curve, so analysers and the Scope Meter stay powered through full test cycles. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm consistent manufacturing quality.

Verify your instrument model

Confirm the device is a Fluke 43, 43B, 120 or a Fluke 123 with firmware below V2.0, and that the original part number is BP120, BP124 or B11483. The pack measures 88.16 x 43.77 x 22.42mm and weighs 291.6g, so check the battery compartment dimensions. Units with newer firmware or different part numbers are not compatible.

Questions about this item

Does the 4.8V 3000mAh Ni-MH pack run hot or draw extra power during all-day use on a Fluke 43B?

The 4.8V 3000mAh Ni-MH chemistry is designed to match the original BP124 specifications, so it delivers the same 14.4Wh capacity without added heat or current draw during extended sessions.

What must I already own for this 3000mAh replacement to work in my Fluke 123 Scope Meter?

You need a Fluke 123 Scope Meter running firmware below V2.0; the pack replaces the original BP120 or B11483 cell and fits the existing battery compartment.

Will this 88.16 x 43.77 x 22.42mm pack sit securely alongside the older BP120 cells I keep as spares?

Yes — the dimensions and 291.6g weight match the legacy BP120 and B11483 packs, so it slides into the same slot and charges on the original Fluke charger without modification.
