Compatible replacement battery

This Cameron Sino VT04 battery replaces the original Fluke 4375741 and FLK-VT04 cells used in VT04, VT04 IR Thermometer, VT04 Visual IR Thermometer and VT04A thermal cameras. It delivers 3400mAh at 3.7V for 12.58Wh capacity and includes a fully decoded chip that works like the factory pack. The pack is certificated to ISO9001, RoHS and CE standards.

Thermal and electrical behaviour

The lithium-ion cell operates safely up to 60°C ambient and weighs 47g. Built-in circuitry protects against overcharge, over-discharge, over-voltage and short-circuit conditions. A fresh unit reaches its best performance after two or three complete charge and discharge cycles.

Build integration notes

Physical dimensions are 68.50mm by 18.50mm by 18.50mm, so the pack fits the existing battery compartment without modification. Installation videos are widely available online for guidance. The package includes shock-absorbing foam for transit protection. Users needing a different voltage, capacity or form factor should look elsewhere.

Questions about this item

How do I install the replacement battery in my Fluke VT04, and what connector step do people miss?

Open the battery compartment, remove the old pack, align the new battery's connector with the device socket, and press firmly until it clicks — the most common mistake is leaving the connector partially seated.

What maintenance will this 3400 mAh 3.7 V pack need over its life?

Expect 2–3 full charge cycles to reach full capacity, then recharge before the voltage drops too low; avoid low-quality chargers and store below 60 °C to maximise cycle count.

What limit appears first when the VT04 runs continuously on this 12.58 Wh battery?

The 3400 mAh capacity sets the runtime ceiling — under sustained thermal-camera use the pack will deplete before thermal or voltage protection triggers.
