Screwdrivers with Ni-Cd battery
Ni-Cd
— nickel-cadmium batteries have been used for a long time and are generally considered outdated; however, they are still popular in power tools due to their relatively small size and weight combined with high capacity, fast charging, and low cost. On the other hand, this type of battery is prone to the "memory effect," which means they should only be charged after being fully discharged; otherwise, their capacity may decrease. Another drawback is that the production of Ni-Cd cells is environmentally unsafe.| clear | Save List |
