thanks a lot to Nero, lifter01 and forkingabout for valuable inputs. We still get reconditioned forklifts with welded cells from Japan (GS and GS Yuasa) and knowing the correct procedure is a must. I will have to find a competent guy (probably a guy with hands on experience) to do the job. Why I wanted to invest in a impedance tester is to analyze all cells of a battery at once, especially at a customer's site. With the impedance tester, identifying the bad cells would be much more accurate.Could you anyway recommend a good multimeter and a hydrometer model for this purpose ?
