Nickel-cadmium batteries contain significant amounts of cadmium, which is a toxic substance that causes allergic reactions. The battery is able to withstand up to 1000 charge cycles, but with each subsequent charge the battery capacity decreases. A nickel-metal hydride battery can be charged and discharged 500 times, but it stands out for its low weight. The most reliable and durable battery should recognize lithium-ion. It has great power, its capacity practically does not decrease over time.
An important parameter is the amount of torque. For use in domestic conditions, 10-15 Nm is sufficient. In professional tool models it reaches 130 Nm.
The next factor is rotational speed. For tightening screws and screws 400-500 turns will be enough. For more serious repairs in the house takes up to 1500 revolutions per minute.
