Replacement battery for AEMC 8500 DTR-8500

This 12 volt lithium-ion pack is built to the original dimensions of 111.66 x 49.10 x 44.80 mm and weighs 537.2 g. It carries ISO9001, RoHS and CE certification and includes a fully decoded chip that communicates with the instrument exactly as the factory cell did. The pack is intended for survey and test professionals who need a direct drop-in replacement for part number 2118.57.

Practical limits of the 12 V 3000 mAh platform

The cell delivers 36.00 Wh at a nominal 12.0 volts, so runtime scales linearly with the meter's current draw. Protection circuitry guards against over-charge, over-discharge, over-voltage and short-circuit events, but the pack cannot be charged safely with low-quality third-party adapters. Storage above 60 degrees Celsius or 140 degrees Fahrenheit is prohibited, and the battery must never be disassembled or exposed to fire or water.

Capacity and headroom for field use

At 3000 mAh the battery supports extended measurement sessions before a recharge is required, and performance stabilises after two or three full charge-discharge cycles. It is not suited for users who need longer endurance than 36 Wh can provide or for instruments that demand a different voltage or form factor. Installers should verify the connector mates correctly before sealing the compartment.

Questions about this item

Is the 3000 mAh capacity the only option for the AEMC 8500 DTR-8500?

Yes, this replacement battery is supplied in a single 3000 mAh / 36.00 Wh configuration that matches the original part number 2118.57.

What does the 12 V 36 Wh rating deliver in the DTR-8500?

It provides the nominal voltage and energy the Digital Transformer Ratiometer expects, enabling normal field-test operation until the next recharge cycle.

How does the battery connect to the instrument?

The pack uses the same connector and decoded chip as the original AEMC 2118.57 battery, so it plugs directly into the DTR-8500 without adapters.
