In the modern world, few people do without digital technology and power tools. The question arises: how to choose the right batteries for a particular high-tech device? What good battery lasts really long? In this article we will consider the main types of batteries and help you choose the most suitable ones for the camera and screwdriver as an example.
Types of batteries for small devices
Conventional AA batteries. These cheap and common sources of nutrition to this day do not give up their positions. They are used in wireless mice and keyboards of economy class, remote controls, cheap cameras, soap dishes, flash units, children's toys, etc.
However, for modern digital photo devices, batteries are not an option - they run out too quickly. So which batteries are best for the camera? It depends on the device itself and the frequency of use. The most popular eco-friendly modern batteries are nickel-metal hydride. They have an operating voltage of 1.2V and a rated capacity in the range of 2500-2700mA / h. Lithium batteries are also suitable for cameras.
What to consider when choosing a battery for the camera?
Firstly, you should not chase a large passport capacity. As practice shows, the manufacturer matters here, so Varta with a capacity of 2700mA / h significantly exceeds the power of Ansmann with a capacity of 2850mA / h.
Secondly, in search of an answer to the question "what good battery to buy?" consider its dimensions - some models have non-standard sizes, because of which they may not be suitable for any device.
Third, consider the intensity of battery use. If you use the camera frequently, you may need to recharge it once a week or more often. In this case, batteries with a capacity of at least 2700mA / h should be used. If the camera is rarely used and their power sources have been “in standby mode” for weeks, use models with a low self-charge current.
Choosing a battery for a screwdriver
The batteries for the screwdriver are of the same types as for the above devices. They differ in a large margin of power. So which battery is best for a screwdriver? Below we describe the features of the main types of these devices, and which battery to take is up to you.
Nickel-cadmium batteries contain many toxic materials and the strongest allergens, but at the same time they have a much larger volume compared to others. Allowed up to 1000 reloads.
Nickel-Metal Hydride Batteries. They are harmless and environmentally friendly, but in comparison with nickel-cadmium ones they have a half power and a permissible number of reloads of 500.
Lithium batteries. More powerful than previous versions and without a memory effect, but at the same time they are poorly tolerated by negative temperatures.
As for the rated power, here the recommendations are the same as for the batteries for cameras. So decide which battery is good and which is not.
What to consider when choosing a battery for a screwdriver?
Memory effect. Present in nickel batteries. The essence of the effect is the loss of capacity when charging a battery that is not fully discharged. That is, in order to ensure the normal operation of such a battery, it is necessary to completely discharge it before charging, which brings certain inconveniences.
Capacity. The larger it is, the longer the battery will last without recharging. Modern models allow you to work continuously for hours.
Charging time. Important: the battery should be charged no more than the time taken to discharge.
That, in fact, is all. We hope that the question of which battery is good and which is not is no longer for you.
