What battery capacity to choose

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

The best 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. You should pay attention to the products of the following firms:

1. Varta;
2. Bosch;
3. Topla;
4. Exide;
5. Volat;
6. Eurotop;

Before giving preference to a particular model, you should get acquainted with its characteristics, as well as study user feedback, highlighting their strengths and weaknesses. Useful information can be found on the Internet, on thematic forums and social networks.

How big should the battery be?? Types of batteries

Speaking of the concept of capacity, it is necessary to distinguish between specific batteries, depending on the functionality and conditions of their use. The thing is that under the generic name “battery” hides a huge variety of models, ranging from a compact battery AAA-size and ending with a starter battery for a truck tractor.

Portable batteries for electronic devices

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

1. The battery capacity for your cell 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 should give preference to the one with the declared capacity more;
2. Portable power supplies, the so-called Powerbank, are used for charging various electronic equipment. In order to solve the question “what capacity to choose a powerbank,” you should determine which power consumers will be powered by this device, and then divide the capacity of the portable charger by the battery capacity of the device. Ideally, the powerbank should be able to perform 3-4 full charging cycles: if the smartphone battery has a capacity of 4000 mAh, the powerbank used with it should have at least 12000-15000 mAh units;
3. Traction batteries used to power a boat motor or to serve as a 12 volt DC power source should have a capacity of 15-20 Amp-hours or more. The higher the power consumption of the connected device – the higher the battery capacity should be;

What should be the capacity of the battery for the car?

Starting batteries for cars are selected according to the type and power of the engine:

1. Most gasoline-powered cars are expected to install a battery with a capacity of 40 to 80 amp-hours;
2. Diesel cars require a battery of increased capacity – from 80 to 120 ampere-hours for proper operation;
3. Trucks that run on heavy fuel and have a large engine volume require a powerful battery, the capacity of which can reach 150-200 ampere-hours;
