I have refurbished 4 NEC battery packs. One I did with 4 NiCad batteries. the other with4 NiMH. Both charge and work fine, but exhibit the problem where the low battery light comes one after about 45 minutes even though there are hours left in the pack. This is true of the original NiCad batteries as well.The other two I built up using ten 1/3 AA NiMH batteries. Basically two banks of 5 batteries. I really like the way these work. The only problem I have had was that on the initial charges, the low battery light never came on and the unit just died when the batteries were too low. But after doing three or four charge/discharge cycles, I get a low battery light when there are about 30 minutes of change left. These are the two packs that stay in my units almost all the time and I will probably rebuild my other 4 battery packs this way. Kurt
