Ni-Cd
— nickel-cadmium batteries have been around for a long time and are generally considered obsolete; 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, batteries of this type are subject to the "memory effect", which is why it is worth charging them only after they are completely discharged — otherwise, a decrease in capacity is possible. Another disadvantage is that the production of Ni-Cd cells is environmentally unsafe.
