Cameron Sino 7000mAh 6.0V NiZn Battery 2129.91 for 6240/6250

Direct replacement for 6240 and 6250 micro-ohmmeters

This 7000mAh nickel-zinc pack is built to the original equipment dimensions of 104.60 x 69.00 x 70.50mm and carries a 6.0V nominal rating. It fits the 6240, 6240 Micro-Ohmmeters, 6250 and 6250 Micro-Ohmmeters models using part number 2129.91. The fully decoded chip communicates with the instrument exactly as the factory cell does.

Steady 42.00Wh output for extended field sessions

Nickel-zinc chemistry delivers a flat discharge curve so the meter maintains measurement accuracy throughout the cycle rather than tapering off early. Over-charge, over-discharge, over-voltage and short-circuit protection circuits guard the pack during long days of continuous testing. The 800.0g mass sits securely in the instrument cavity without shifting under vibration.

6.0V nominal voltage matches the original

The meter’s power regulation expects this exact potential; a higher or lower voltage would cause reading errors or shutdowns. Buyers whose instrument requires a different cell voltage or a non-standard connector will need a different pack. Always verify the part number 2129.91 against the label on the battery being replaced.
