Replacement battery for AEMC micro-ohmmeters

This Cameron Sino battery replaces the original power pack in AEMC 6240 and 6250 series micro-ohmmeters. It delivers a nominal voltage of 6.0 V and a rated capacity of 7000 mAh, matching the factory specification for these instruments. The pack measures 104.60 x 69.00 x 70.50 mm and weighs 800.0 g. It is a direct fit for part number 2129.91.

Sustained field operation

The lithium-ion chemistry provides stable output during extended measurement sessions rather than only brief peaks. A fully decoded chip communicates with the meter so the fuel gauge remains accurate over repeated charge and discharge cycles. ISO9001, RoHS and CE certification confirms consistent manufacturing quality for professional survey and test environments. Overcharge, over-discharge, over-voltage and short-circuit protection circuits guard the cells during long deployments.

Capacity and voltage match

The single specification that determines compatibility is the 7000 mAh capacity at 6.0 V, which must match the original battery exactly. If your instrument requires a different voltage or a significantly different amp-hour rating, this pack will not function correctly. Verify the part number 2129.91 on your existing battery before ordering.

Questions about this item

Does the 7000mAh lithium-ion pack run hot during a full day of micro-ohmmeter testing?

The battery is rated at 6.0 V and 42.00 Wh; normal operation in the AEMC 6240 or 6250 does not generate noticeable heat.

What must I already own to use this replacement battery?

You need an AEMC 6240, 6240 Micro-Ohmmeter, 6250 or 6250 Micro-Ohmmeter with the original 2129.91 battery compartment and connector.

Will the 104.60 × 69.00 × 70.50 mm pack fit the older 6240 Micro-Ohmmeter I still use?

Yes — the dimensions and the decoded chip match the original 2129.91 specification for both the 6240 and 6250 series.
