A: In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. One could be called the cubic, and the other face centered cubic, or nested. However, if you apply a voltage equal to the allowable maximum (or even less, depending on the start of charge of the cells) and don't have . We build lots of custom batteries for small business every year. 3. The best way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour). 5. i believe i read that there is some sort of low voltage cut off electronic device in the battery pack and there is also a fuse made into dewalts tabs that connect all the batteries together. The following balancer for Ni-Cd or Ni-MH keeps the battery pack in balance and additionally limits the charge . It is perfectly OK if the current is far below the maximum.
