Ni-Cd tool batteries
prices on 3 models Ni-Cd (nickel-cadmium)
— the most "old" option found in modern power tools. It is distinguished by high reliability, resistance to temperature extremes and good charging speed even with high capacity (which is important, given the "voracity" of the power tool). The main disadvantage of this type of battery can be called a pronounced "memory effect"; — a decrease in battery capacity in the event that it is set for charging without being completely discharged. In addition, Ni-Cd cells are considered environmentally unsafe. Nevertheless, they are still used in tools — not least due to their low cost with decent performance.
