Batteries are needed for many devices and machines: telephones, tablets, cars, etc. Their stores offer a wide range. Below is a battery rating with a specific description.
Which batteries are better to choose
Most devices are powered by batteries. Manufacturers offer a variety of finger and little finger batteries. Many people opt for batteries that can be recharged many times.
When choosing reusable power supplies, you should adhere to the following rules:
- Before buying, you must carefully read the instructions for the device to which the batteries will be purchased. Sometimes it contains information about the form of the necessary power source;
- if the device is small in size, then it is better to take it with you to the store. If this is not possible, then it is worth remembering that the little finger batteries are marked AAA, and finger batteries are AA;
- it is worth considering the conditions in which the device will be used: if it is planned to be used both in summer and winter, indoors and outdoors, then it is necessary to choose those that will be resistant to sudden changes in temperature. These include nickel-cadmium type batteries. Their disadvantages: short term use, it is possible to put on charge only after a full discharge;
- when using the device in conditions of average temperature, it is worth choosing a battery marked NI-MH. They are powerful, have a long service life, they do not need to be fully discharged before charging. However, they quickly fail in extreme heat or frost;
- It is worth comparing the voltage parameters of the device with those indicated on the battery. Sometimes indicators may not match;
- with constant use of the device, it is better to purchase two pairs of batteries.
The best battery manufacturers include:
- Panasonic Eneloop: it is possible to charge 2100 times, it can be used even after ten years of storage, the capacity for AA is 1900 mAh and 750 mAh for AAA, a small level of self-discharge. Price 375 p.

Also, when choosing a device, it is worth considering reviews, expert opinions, and voting results.
TOP 5 best car batteries
The battery for the car helps to start the engine, and also transfers electricity to the on-board network. It is a chemical current source, the feature of which is the ability to use it several times.
All car batteries are divided into:
- Economy class;
- standard class;
- premium class.
Also, batteries are divided into two types:
- acidic: sulfuric acid and distilled water (liquid electrolyte) are located inside. This composition provides the accumulation of charge. When the electrolyte begins to boil, this means that the battery has accumulated a charge and can be removed from recharging;
- gel: an innovative product. It uses high quality lead. This provides quick charging and discharging. It can stand idle without loss of capacity for up to two years. Service life is up to 15 years.
They cost an order of magnitude more expensive than acid.
When choosing which battery to buy a gel or acid one should take into account that gel batteries are much more expensive. They can also fail at very low temperatures.
Higher-quality models have a longer life, increased warranty and starting current level.
The top five best batteries for a vehicle include:
- BOSCH S4 005: the cost of 4 950 rubles. Capacity 60 mAh, current 540 A. Service life on average 4 years. With it, the vehicle is easily wound up in mild frosts. At a temperature of -30 degrees with the launch, complications can occur.

The following factors influence which company should choose the battery for the vehicle:
- capacity: for each vehicle model this parameter is different. The maximum capacity of the battery, which is fully charged, is indicated on the case:
- dimensions and type of connection of the terminals: when choosing, it is better to consult a car service;
- starting current: represents an indicator of energy input to the starter. It depends on the class and size of the battery.
The standard battery is designed for use at +27 degrees. Under such conditions, the battery produces 100 percent of its power. If the temperature drops to -18 degrees, then the power source loses up to 60% of power.
Therefore, in areas with a cold climate, it is necessary to purchase a battery that has a capacity twice as large.
Which is better to choose the capacity for the battery
The capacity of a power source characterizes the amount of time during which it can power a device connected to it. For car batteries, this indicator is measured in ampere-hours, and for tablets and phones - in milliampere-hours.
If a larger capacity battery is installed in the device, this will not mean an increase in the productivity of its operation, since technical values must also be taken into account.
To select the battery that best suits the device, you need to take into account the number that is written on the battery case.
When choosing a battery capacity, you should rely on engine volume indicators:
- with a volume of 1 to 1.9 l, capacity - 55-60 A / h;
- if the car is an SUV with an engine capacity of 1.4 to 2.3 liters, then the optimal capacity of the power source is 66 A / h;
- a truck with an engine capacity of 1.6-3.2 liters, a capacity of 1.6-3.2 liters is suitable;
- vehicles with an average carrying capacity (1.9 - 4.5 l), capacity 77 A / h;
- for a large truck with an engine displacement of 3.8 - 10, 9 mAh;
- bulldozers and excavators: require a battery of 190 Ah / h.
The most suitable option for a car from 50-65 A / h.
With a larger capacity, the battery is worth buying if the device is equipped with additional features that require an additional power source. These include: vehicle navigator, radio, heater, etc.
However, you should not use a power source that is much higher than necessary. The battery will not be able to recharge and lose its characteristics. A starter with a larger capacity will work more intensively, but this will lead to wear.
When choosing a battery for a cell, you need to consider that its characteristics coincide with the potential of the power source.When buying a battery for your phone, you should take into account the following factors:
- with a battery capacity of 2,000 - 2,500 mAh, recharging is necessary once a day;
- capacity 3,000 - 4,000 mAh - recharging once every two days;
- 5,000 mAh capacity - recharging needed once a week.
If the cell will be used only for talking and reading books, then a small enough capacity of the power source. If it is used to watch movies, then the capacity should be at least 4,000 mAh.
Which is better to choose a battery for winter
When choosing a battery for a vehicle that is suitable for winter conditions, you should adhere to the following rules:
- Before buying, read the operating instructions for the car. If it does not have a clear indication of a specific type of battery, then a wide selection opens;
- pay attention to electric capacity. With an increase in its indicator, more energy is spent to start the engine;
- the battery must meet the technical requirements of the car;
- see the condition of the filler plug. When the battery is charging, water decomposes into oxygen and hydrogen. For a free exit of gas, a special hole is made in the plug;
- for winter conditions, the best battery will be the one that has a larger capacity. The selection of the battery value is carried out in the following dependence: with a more powerful motor, the battery will be larger, and the capacity indicator is higher.
For a good choice of battery for winter, it is worth considering the climate of a particular area. Combined for the central part of Russia. battery type. For the northern regions, it is better to take the calcium type.
The most famous battery models suitable for use in winter conditions include:
- VOLTON 6CT-55.1 - combined view;
- VOLTON PROFESSIONAL 6CT 55.1 - combined;
- VARTA 6CT - 63 SILVER Dynamic - calcium;
- VARTA 6 CT - 60 Blue Dynamic - calcium;
- BOSCH S5001 - combined, more often used in small cars;
- TOPLS AGM - combined, the model can be used for any vehicles.
When choosing a battery for a car, phone or other mobile device, you should first read the operating instructions. It indicates the recommended types of power source.
