Battery

One of the main parameters of cordless screwdrivers is its battery, because it is about half the cost of the entire tool.Today on the market are tools with three possible batteries.

Heavy, but reliable

One of the most "long-playing" batteries is nickel-cadmium.These batteries are equipped with screwdrivers for home use. Their lifespan can be up to five years, they can be recharged up to 1000 times, have only about 20% percent of self-discharge per month, quite energy-intensive and inexpensive. Among the shortcomings can be noted only large weight and large dimensions.

An important caveat: nickel-cadmium batteries need to be fully charged, otherwise the battery capacity is lost.

Easy but not long

More modern batteries are nickel metal hydride. They are more energy-intensive, smaller in size and weight, more durable and do not fear shock, but can be charged no more than 5 hundred times.The main disadvantage of such batteries is that they do not function at low temperatures.Self-discharge of such batteries is up to one third per month. The nickel-metal hydride battery needs to be fully charged, as it also loses its capacity from incomplete charging.

The most-most, but dangerous

Lithium ion battery

Lithium-ion battery has many advantages, but can be dangerous in operation.

The most modern battery today is lithium-ion.Such a battery bypasses in the parameters of its fellow almost all items. Lithium-ion battery:

  • easy, power-consuming and compact;
  • can be charged up to 7 hundred times;
  • almost does not lose charge during storage;
  • Charges for half an hour;
  • resistant to damage.

But the disadvantages of such a battery are very significant:

  • works no more than two years;
  • sensitive to overheating;
  • does not work in the cold;
  • flammable, may explode when trying to restore it from a discharged state;
  • costs an order of magnitude higher than nickel-cadmium or nickel-metal hydride.

Another point to pay attention to when choosing a battery is capacity. It is determined in ampere hours and indicates how long the instrument will work without recharging. For the device that will be used in home repairs, the best indicators will be from 1.2 to 2.4 A / h. You should also pay attention to the power of the battery; for a household tool, a voltage of 8–13 volts will be acceptable, however, the higher this indicator, the more powerful the screwdriver.

Torsion moment

The torque of the cordless screwdriver is an indication of the strength with which the tool will work.The unit of measurement of this force is newton meters, 15-20 units will be enough for a home appliance, and for professional use you can choose a screwdriver with a force up to 100 n / m.

How to spin

An important parameter when choosing a cordless screwdriver is the speed of rotation. It determines the capabilities of the tool. The higher this figure, the more functional the device will be. So, for work with fasteners it is enough approximately 500 turns in a minute, and here for drilling it is required not less than 1000.

Cartridge

Keyless screwdriver cartridge is simple and easy to use

As a rule, screwdrivers are equipped with standard cartridges, which are fixed with a special key. Such devices are reliable and familiar. However, it is increasingly possible to find quick-change cartridges on the market, which are fixed with clips - they make it possible to change the nozzle as quickly as possible.

Options plus

The final stage of the selection can be considered additional tool options:

  • If necessary, you can consider the presence of the case, which will facilitate transportation and storage.
  • Illumination which will allow to work in the conditions of weak lighting will be useful.
  • The spindle lock can be selected because of the ease when changing nozzles.
  • A mandatory addition is the reverse (reverse) rotation function, without it it is difficult to imagine a modern screwdriver as such.

  • Bosch GSR 1440-LI;
