Compatible replacement battery

The Centenex Electronics DS-CS-EXR500SL is a lithium-ion battery built for the Extech VIR 50 and VIR50 Dual-Laser IR Video Thermometer. It replaces the original BATT-37V pack and arrives in new condition with 100% OEM compatibility. The blue casing matches the factory look. It is intended for technicians who need a direct swap for a depleted original cell.

1600 mAh capacity and runtime

Rated at 3.7 V and 1.6 Ah, the pack stores 5.92 Wh of energy. That capacity powers the thermometer through typical inspection sessions without adding bulk. Runtime scales with the instrument’s own draw, so heavy continuous recording will drain it faster than intermittent spot checks. The cell chemistry holds charge well between jobs.

Compact li-ion cell for instrument bay

The battery measures 52.35 x 18.40 x 18.40 mm, sliding into the thermometer’s dedicated compartment without adapters. Its li-ion chemistry avoids memory effect, so partial recharges do not reduce usable capacity. The pack frees the user from hunting for disposable cells and keeps the tool ready for the next thermal survey.

Questions about this item

Will this 3.7 V 1600 mAh Li-ion cell power my Extech VIR 50 thermometer the same way the original BATT-37V did?

Yes — it matches the 3.7 V 1600 mAh rating and is listed as 100 % OEM compatible for the VIR 50 and VIR50 Dual-Laser IR Video Thermometer.

How can I confirm the battery is working correctly once installed?

The thermometer should power on and operate normally; a full charge delivers 5.92 Wh, so run-time should match the original pack.

What comes in the package and do I need any extra parts?

One blue DS-CS-EXR500SL battery (52.35 × 18.40 × 18.40 mm) is included; no additional hardware is required for the VIR 50.
