Decided to buy a screwdriver for home use? Can't decide on the type of tool: mains or battery? Let's try to understand the advantages and disadvantages of screwdrivers on a battery.
A cordless tool is no worse than a power tool
Before making your choice, you should determine exactly what types of work you plan to carry out through its use. For frequent and prolonged use, it is better to buy a model with an electric motor. But she also needs to be given periodic rest. Otherwise, the motor may burn out.
The quality and efficiency of network units depends not only on the professional skills of the master, but also on the constancy of voltage in the network. If it is impossible to provide a constant voltage of electricity, it will be difficult to work with such a tool.
Models with a battery are not inferior to network analogues. This is due to independence from the power source. When working, you will not need to look for an electrical outlet. It is suitable for work, both for professionals and novice masters.
The mobility of this type of equipment is one of its main advantages. This is ensured by the absence of a network wire, which limits maneuverability during operation.
Despite the fact that the battery capacity is limited, if you have an extra battery, you don’t have to worry about the work stopping in the middle of the process (while one battery is in operation, the other can be recharged).
The cost of a tool whose battery power supply is several orders of magnitude lower than that of network equipment.
Such models are more practical, mobile and energy efficient than their network counterparts.
Power is determined by torque
Torque is the rotational force that a screwdriver is capable of developing. This indicator has a direct effect on tool power: the higher the torque, the greater the power of the equipment.
The design of modern models of screwdrivers is designed in such a way that the master has the ability to adjust the amount of torque. This indicator for battery models ranges from 10-60 Nm.
Experienced craftsmen do not recommend purchasing screwdrivers with a maximum power level. This will lead to the fact that its torque will be so large that the screw head can fall below the work surface, spoiling the appearance of the product.
It is better to opt for models with an average level of torque and power.
Battery Memory Effect
A phenomenon such as the battery memory effect is predominantly characteristic of nickel-cadmium or nickel-metal hydride batteries. In the process of their operation is a gradual decrease in capacity. The reason is that the battery functions by giving up its charge until the moment when it was last charged.
The reason for the appearance of this phenomenon lies in the too frequent recharging of the battery, which has not yet had time to discharge to the maximum.
Modern cordless screwdriver models support the REFRESH function. Due to this, before recharging the battery is subjected to violent additional discharge to its minimum level.
Cordless screwdrivers of modern manufacturers stand in one place with network tools, not inferior to them in productivity, efficiency, mobility and efficiency of use.
Interestingly written: the cost is several orders of magnitude higher. Is it 10 or more times? Well, you guy bent! Mathematician horseradish
Especially when you consider that the cost of battery is always significantly higher, ceteris paribus. The "author" simply quashed someone else's article for the sake of an advertising link at the end, but did not understand the topic, since it was essentially a humanitarian asshole.
The most important indicator of a lithium-ion screwdriver is the battery capacity. The higher it is, the longer it will work on one charge cycle
“For frequent and long-term operation, it is better to buy a model with an electric motor.”, And for a rare one - with a gasoline.
