Today, few people will come to mind with a hand drill or a set of screws with an ordinary screwdriver. It is much more convenient to purchase a compact and efficient cordless screwdriver. There are a lot of models and brands of this equipment, and it is quite difficult for a person who does not understand this issue to make a specific choice. Let's try to clarify the situation and determine which cordless screwdriver is better according to user feedback and declared characteristics.
Since this material is about cordless screwdrivers, before starting the comparison and reviews of the tool, clarify what types of batteries are, which positive and negative sides they possess and which one is preferable.
Nickel Cadmium (NiCd). The largest dimensions, which is not always convenient for reasons of compactness, are batteries called nickel-cadmium and denoted by "NiCd". They are fairly cheap and work like a clock - without a glitch, and both at high temperatures and at low temperatures. You can charge them an impressive number of times. But the memory effect present here can serve an unkind service, in order to avoid what a similar battery is sent to storage discharged completely, to zero. Charging is also carried out only when the battery finally sits down.
The memory effect is the loss of battery capacity and, as a result, its less prolonged use between recharges. If you do not wait for the full discharge of this battery, it will again be recharged, it "remembers" that it was not fully consumed and in the future will give not all the energy, but only the amount that reaches this limit. You have to constantly monitor the battery charge level. Owners of the instrument with such batteries often ignore the moment, as a result, part of the capacity is gradually lost.
Nickel metal hydride (NiMH). Batteries, called nickel-metal hydride batteries, are labeled "NiMH". They are one hundred percent environmentally friendly and weigh very little. Another significant advantage is their ability to work long enough without requiring recharging. The memory effect of these batteries is present, but not as pronounced as the previous type. Alas - they have a significant disadvantage. This is the inability to withstand frost. Even when it’s just minus two degrees outside, this battery starts to discharge itself. Keep the screwdriver in the garage without heating or in the trunk of a car is impossible. For storage, this type of battery must also be charged.
Li-ion (Li-Ion). The third type of battery is a lithium ion battery. Marked by "Li-Ion". They appeared later than all - in 1991, in the mass issue of becoming the brainchild of the Japanese corporation Sony. They are distinguished by the absolute absence of a memory effect, a large capacity and a long charge retention. Weigh by forty percent less than the above analogues. They can be charged in any condition - at any level of charge. Such batteries are often put on professional models, especially on screwdrivers, combined with a drill.
1. What does the capacity of the battery mean? The capacity, the unit of measurement of which is called ampere-hour (A / h), determines the duration of the tool’s operation without recharging. Accordingly, there are household tools (the capacity of which ranges from 1.3 to 2 A / h) and professional tools with a capacity exceeding 2 A / h.
2. Charging speed. It is important in the case when you need to do work quickly. For household, not too expensive tool, this characteristic varies from 2 to 12 hours. But professional models can be charged in an hour, or even in half an hour. Typically, these tools have lithium batteries and a pulsed charger.
3. Battery voltage. Battery voltage, can range from 3 to 36 volts. In this case, the torque of the model at 14.4 V and 12 V can be the same. In turn, the torque determines the power of the screwdriver, and you might think that buying a tool with a large voltage is not advisable. In fact, a 14.4 V battery is capable of maintaining a maximum tool power for a longer period and, as a result, it can work for a longer time, until the moment when the battery charge drops to reduce the power of the screwdriver.
Comparison of batteries of different types:
Before you understand how to choose a cordless screwdriver, you must determine which firms are the best and let out the most demanded products in the market.
