I have a scanner that I am changing over the battery pack ( 4 cells in series) from a Nicad to a Nickel Metal Hydride. This will change the mah from about 2400 to 7200. Im going to use the Nicad wall charger. My question is will the current demand for the new battery pack exceed the demand of the wall charger? The new battery pack should charge at about .7 amps (7.2 ah / 10). The old Nicad should have been about .24 (2.4 ah / 10). The other question is How is the charging current demand determined? Would it be calculated from internal battery resistance?
Thanks
