For more than a dozen years, humanity has been accompanied by batteries. They are used in many types of electronics: toys, flashlights, radios, CD-players, cameras, clocks, various control panels … But one day the moment comes when the battery runs out and needs to be replaced. Moreover, some batteries can last a very long time, while others are discharged in just a couple of hours. What does it depend on?
First, it depends on the battery itself - its voltage, amperage and capacity. The higher these indicators are, the longer the battery will last. Secondly, the ambient temperature affects the rate of discharge - at high temperatures, battery life is significantly reduced. Thirdly, a lot also depends on the electronics in which the batteries are used - more complex devices use up their potential faster. And fourthly, they tend to discharge themselves over time. The rate at which the batteries discharge themselves depends on the same factors as when using the battery.
If the charger runs out in the device, it should be replaced. Replacing the batteries is not a complicated procedure, as every portable electronics has special signs that allow you to replace the battery correctly - these are the signs "+" and "-". The same designations are also found on batteries. To replace the batteries, you need to correlate the same signs on the device or the chargers themselves. If the contacts are confused, then the device will naturally not work. In addition, it may simply break from this.
There are two types of batteries - disposable and rechargeable. The former are not rechargeable and should therefore be disposed of after use. And rechargeable batteries can be charged every time they sit down. Of course, you won't be able to use the same rechargeable batteries forever, since they also have an expiration date. It depends on the fact that such batteries provide a certain number of recharge cycles, so over time you will still have to replace them with new ones. Rechargeable batteries initially last a very long time - from several weeks to months. But after a while, their charge is only enough for a couple of hours. It depends on the same conditions as for conventional batteries. Replacement of such devices is carried out in the same way as for conventional batteries.
