Replacement Battery for Fluke Calibrators

The Estry DSP-100 is a 7.2V Ni-MH battery built to match the original specifications for Fluke calibrators and cable testers. It fits models such as the DSP-100, 744 Calibrator, Impulse 6000D and DSP-4000PL among others. Technicians who need a direct replacement for part numbers 116-066 or BP7235 can use this pack. It is not for users requiring a different voltage or chemistry.

3500mAh Capacity for Extended Field Use

Rated at 3500mAh and 25.2Wh the pack delivers more stored energy than the 3000mAh reference in the specifications. This headroom supports longer measurement sessions on the 740 Calibrator or Impulse 7000DP before a recharge is needed. Runtime will fall when the load draws high current continuously or when the cells age. It does not suit devices that demand a higher nominal voltage.

Protected Cells with Certified Safety

Built-in protection guards against overcharge over-discharge over-voltage and short circuits to preserve cycle life. The pack carries ISO9001 RoHS CE UN38.3 and MSDS certifications confirming compliance with international safety and environmental standards. At 491.0g it adds measurable mass to handheld units. No active cooling is present so sustained high-current discharge will raise cell temperature.

Questions about this item

Will the Estry DSP-100 7.2V 3500mAh Ni-MH battery fit my Fluke 744 Calibrator that currently uses a BP7235 pack?

Yes, this replacement is listed as compatible with the 744 Calibrator and matches the BP7235 part number, so it will fit and power the instrument.

How can I verify the battery is performing correctly after installing it in my DSP-4300 cable tester?

The tester should power on and run its self-test without a low-battery warning; a full charge delivers 25.2 Wh at 7.2 V, matching the original runtime.

Does the box include a charger or only the 153.2 x 54.9 x 20.9 mm, 491.0 g battery pack?

Only the Ni-MH battery pack is supplied; a compatible charger for 7.2 V Ni-MH cells must be purchased separately.
