What is the battery capacity to choose

Despite the fact that modern batteries differ not only in terms of manufacturing, but also in purpose, the main criterion determining suitability for operation in specific conditions, as well as the duration of its work on a single charge, is capacity. This parameter reflects the amount of current that a fully charged battery is capable of producing for 20 hours of continuous operation. The greater this value, the less often you will have to charge the battery.

Top Battery Manufacturers

The manufacture of compact batteries is currently engaged in a large number of European and Japanese firms, for many of them such devices are the main specialization. Pay attention to the products of the following companies:

1. Varta;

2. Bosch;

3. Topla;

4. Exide;

5. Volat;

6. Eurotop;

Before you give an advantage to a particular model, you should be familiar with its characteristics, as well as examine the feedback from users who have identified their strengths and weaknesses. You can find useful information on the Internet, on thematic forums and on social networks.

What should be the capacity of the battery? Types of batteries

Speaking of such a concept as capacity, it is necessary to distinguish between specific batteries, depending on the functional purpose and the conditions of their operation. The thing is that under the general name "battery" hides a great variety of models, starting with a compact AAA-size battery and ending with a starting battery for a tractor unit.

Portable batteries for electronic devices

The capacity of such devices is measured in milliampere-hours and the higher it is - the longer a smartphone or camera will work without the need for recharging.

1. The capacity of the battery for a mobile phone or smartphone must match that of the original battery installed by the manufacturer. On sale there are models from 600 mAh and up to 3500-4000 mAh, when choosing, preference should be given to the one whose declared capacity is larger;

2. Portable power sources, the so-called Powerbank, are used to charge various electronic equipment. In order to solve the question “which capacity to choose a power bank”, one should determine which energy consumers will be powered by this device, and then divide the capacity of the portable charger by the device battery capacity. Ideally, the powerbank should be able to perform 3-4 full charge cycles: if the smartphone battery has a capacity of 4000 mAh, the power bank used with it should have at least 12000-15000 mAh units;

3. Traction batteries used to power the boat electric motor or that serve as a source of direct current for a voltage of 12 Volts must have a capacity of 15-20 Amp-hours or more. The higher the power consumption of the connected device - the higher should be the battery capacity;

What should be the battery capacity for a car?

Starting batteries for the car are selected depending on the type and engine power:

1. Most gasoline-powered cars require a battery with a capacity of 40 to 80 ampere-hours;

2. Diesel cars require an increased capacity battery for proper operation - from 80 to 120 ampere-hours;

3. Trucks that run on heavy fuel and have a large engine size require a powerful battery, whose capacity can reach 150-200 ampere-hours;
