Replacement Battery for 6240

This 6.0 V nickel-zinc pack replaces the original cell in 6240, 6240 Micro-Ohmmeters, 6250 and 6250 Micro-Ohmmeters equipment. It delivers 7000 mAh capacity and 42.00 Wh energy for survey and test applications. The part number 2129.91 confirms direct compatibility with the listed models.

Installation Notes and Common Pitfalls

The pack measures 104.60 x 69.00 x 70.50 mm and weighs 800.0 g, matching the original footprint for a straight swap. Many installation videos are available online showing the connector alignment. The main issue is reversing the connector or using a low-quality charger, both of which can prevent the battery from reaching full performance after the first two or three charge cycles.

Capacity and Voltage Determine Fit

The single specification that decides suitability is the 7000 mAh capacity at 6.0 V, which must match the original battery exactly. If your device requires a different voltage or a significantly higher or lower amp-hour rating, this pack will not power the instrument correctly.
