In the modern world, few do withoutdigital technology and power tools. The question arises: how to choose the right batteries for one or another high-tech device? What good battery will last really long? In this article we will look at the main types of batteries and help you choose the most suitable for the example of a camera and a screwdriver.
Types of batteries for small devices
Conventional AA-format 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, flashlights, children's toys, etc.
However, for modern digital photo devicesbatteries - not an option - too quickly they sit down. So which batteries are better for a camera? It depends on the device itself and the frequency of using it. The most popular are environmentally friendly modern nickel-metal hydride batteries. They have a working voltage of 1.2V and a passport capacity in the range of 2500-2700 mA / h. Lithium batteries are also suitable for cameras.
What should be considered when choosing a battery for a camera?
First, you should not chase the passportlarge capacity. As practice shows, the manufacturer matters here, so the Varta with a capacity of 2700 mA / h considerably exceeds the Ansmann power with a capacity of 2850 mA / h.
Secondly, when looking for the answer to the question “what kind of good battery to buy?”, Consider its dimensions - some models have non-standard dimensions, which may not suit every device.
Third, consider the intensity of use.batteries. With frequent use of the camera, it may be necessary to recharge once a week or even more often. In this case, use batteries with a capacity of at least 2700mA / h. If the camera is rarely used and their power sources are “in standby mode” for weeks, use models with a low self-charging current.
Choose a battery for the screwdriver
Batteries for the screwdriver are presented the sametypes as for the above devices. They differ in a large power reserve. So which battery is better for a screwdriver? Below we describe the features of the main types of these devices, and you decide which battery to take.
Nickel-cadmium batteries contain many toxic materials and the strongest allergens, but at the same time have a much larger volume compared to others. Up to 1000 recharges are allowed.
Nickel-metal hydride batteries. They are harmless and environmentally friendly, but compared to nickel-cadmium, they have a capacity of half as much and an acceptable number of recharges of 500.
Lithium batteries. More powerful than the previous options and without a memory effect, but at the same time negative temperatures are poorly tolerated.
As for the power rating, the recommendations here are the same as for batteries for cameras. So decide which is a good battery and which one is not.
What should be considered when choosing a battery for a screwdriver?
Memory effectPresent in nickel batteries. The essence of the effect is in the loss of capacity when charging a fully discharged battery. That is, 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 work without recharging. Modern models allow you to continuously work for hours.
Charging time Important: the battery should be charged no more than the time spent on discharge.
That's all. We hope that the question of what a good battery, and what is not, for you is no longer worth it.
