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.

Questions about this item
Does the 7000mAh 6.0V nickel-zinc pack run hot during all-day survey use?
The battery is rated for storage up to 60°C and 140°F; normal operation in 6240 or 6250 micro-ohmmeters stays within that range.
What must I already own to use this 2129.91 replacement pack?
You need a compatible 6240, 6240 Micro-Ohmmeter, 6250 or 6250 Micro-Ohmmeter that accepts a 104.60 x 69.00 x 70.50 mm pack.
Will this 42.00Wh pack work alongside the original charger I kept for my 6240?
Yes, the fully decoded chip matches the original specification so the existing charger recognises it without modification.
