Today, the basis for the functioning of many devices are rechargeable batteries, which are distinguished by their durability when compared with conventional ones. But this is not the only advantage that rechargeable batteries have, they can also be charged. So you can save money on acquiring new ones. When used properly, they can last a huge period of time.
Rechargeable batteries
If you do not adhere to the correct charging mode, you can shorten the battery life or completely kill it. How much does a regular battery charge?
How much to charge and how to properly recharge the batteries?
At the very beginning, you need to figure out how to properly recharge the battery. If it is improperly charged, the service life will be significantly reduced.
You should first carefully read the instructions that accompany the device. In the instructions, you can find the charging time. But it may be that the instruction is missing. In this situation, you must use universal rules. Let's consider them in more detail:
- Battery Charging Time. How to calculate the charging time of an ordinary battery? If there is no information, then try to make the calculations yourself. Battery capacity required. It must be divided by the charging current, and in the end, multiply everything by 1.4. As a result of these calculations, we get a number that indicates the amount of charging time. Depending on the location, there may be a different time value. Consumption in camcorders is higher when compared with cameras.
- Action with a new battery. To increase the operational life to the maximum, a technological process called molding is carried out. You need to fully charge the battery 3-4 times. Remember that immediately after purchase it should be completely discharged. After that, charging is carried out, which takes a sufficient amount of time. In no case should you interrupt charging. After fully charging, the device must be discharged again. This procedure has 3-4 repeated cycles.
- If it was not possible to calculate the charging time, then it is necessary to focus on general values. General values - 10-14 hours. Checking the full charge is carried out as follows: you need to touch the surface of the device. If the surface is warm, then the battery can already be used.
Battery Charge
Charge interruption
Is it allowed to interrupt this process? Today, all people are constantly in a hurry, so charging their devices is not always possible. But you need to try not to do this and allow the battery to fully charge. Only in this case will it be ready for operation. Due to the frequent interruption of this process, the quality of the device and other technical characteristics will suffer, and the operational life will be reduced.
Temperature reduction process
Before charging, allow the battery to cool. Therefore, after using the battery, you must leave it for an hour and a half or more. The temperature to be reached by the device is 20-25 ° C (room temperature).
In the cold, the unit can not be kept either, as it does not withstand sudden changes in temperature. The quality of the device will deteriorate.
Storage
To prevent the device from deteriorating, you must store it correctly. If you do not need to use the battery for a long period of time, charge it fully. After 30 days, check. If the charge becomes less, then also fully charge the battery.
Additional tips
Depending on the battery device, they can charge a different amount of time:
- An acid battery made of lead and used in a car is charged with a current of 0.1 of the nominal value. The time is ten hours. If the capacity is 50 A / h, then a current of 5 A is required. The condition of the lead plates from a full charge will not deteriorate.
Lead acid battery
- Another view is nickel-cadmium batteries. Types - finger and little finger. For the charging procedure, chargers are used, which indicate the required current value. To determine the time, use the calculation method described above.
Nickel Cadmium Batteries
- Polymer batteries made of lithium. The battery is charged using pulsed currents. The charge control is carried out using the charger processor. Time depends on the current. The time range is 30-60 minutes.
Lithium polymer batteries
The first two types of batteries must be fully charged. But the last type does not need to be charged, a full charge is a murder for them.
Charging methods
There are several methods by which you can charge the battery. Consider three ways to charge the battery:
- The device is charged using constant current. This method is the fastest.
- The device can be charged using constant voltage. You can apply a varying voltage or a constant.
- The latter method is a combined one. This method is divided into two stages. First you need to apply a constant current. The value of current should be a tenth of the nominal value. When the voltage reaches 14.5 V, a constant voltage is turned on. The second step involves applying a constant voltage. The current strength becomes smaller, because the internal resistance becomes larger.
The last method considered is the most optimal if time is not the main factor. Gas formation and hydrolysis will be ruled out. This is due to the supply of high voltage.
Do not forget that after the next recharge, the battery life becomes worse. Batteries that are nickel-cadmium have only 1000 discharge / charge cycles.
Modern power components can have up to 3500-4000 discharge / charge cycles. How to use the battery, read the technical documents and instructions. This article will also help you.
The service life of an ordinary average battery is three years or a little less. Remember that devices cannot be recharged.
