hi i replace the fluke 2000 mah with the 4000 mah battery.
what i did is i remove the wired connection from the original battery pack and installed on the 4000 mah 1.2 volts 4 cells.
now the problem is after charging the battery the battery drains very quickly.
does the battery need completer refresh .
when select the refresh option it shows 12 hours.
any suggestion.
thank u
