What Does Battery Charger Do?

What is Battery Charger?

 Battery chargers are devices used to ensure that the batteries are filled. There are different programmes in battery chargers. With these programmes, the batteries can be filled in the best way.

 Battery chargers usually have 8 or 9 programmes. The purpose of these programmes is to fill the batteries in the best way and get the highest performance. A high current is applied to ensure the filling process of the batteries.

 While maintaining the optimum voltage in the smart chargers, the process of decreasing the current is also provided. Thus, the battery is gradually filled up to the full filling level. Battery chargers generally analyse how the battery receives and holds the charge. Thus, the battery is charged in the best way. Smart battery chargers are constantly connected to battery devices that have decreased performance and are no longer used, allowing them to work. This provides a great advantage.

What Does Battery Charger Do?

 An average battery capacity in the car is around 48 Amps. A normal battery device has the ability to charge approximately 2 amps per hour. It is seen with a simple mathematical process that it takes 24 hours to fill the battery with a capacity of 48 Amperes.

 Battery chargers vary between those with charging capacities between 2 and 10 amps per hour. The higher the charging output in a battery charger, the faster the battery can be charged. However, it should not be forgotten. Charging a battery at high speed can cause damage to the battery plates. For this reason, fast charging of batteries is not a preferred situation.

 Battery chargers include transformers and rectifiers. Thanks to these, alternating current is easily converted to direct current. Battery chargers convert the mains electricity into a current suitable for the battery and allow the batteries to be charged easily.

End-of-life batteries sometimes cannot be charged under any circumstances. In such cases, chargers send low pulses of 6 amps to the battery and allow it to charge. For this, the battery charger must have a high and low current switch.

 How to Use a Battery Charger?

 Some of the batteries have a one-piece and centred battery cover. In such cases, the electrolyte level must be checked before connecting the battery to the charger. If there is a low level, it must be filled first before the battery starts to be filled.

 Before starting the battery charging process, the battery terminals must be cleaned well. If there is an alternator in the vehicle, it must be disconnected from the battery after the filling process. Because especially old type alternators can be damaged during battery filling.

If the battery has cell covers, these covers must be removed in order to perform the ventilation process. The battery charger clamps must be properly connected to the + and - poles of the battery.

 It is possible to understand whether the battery is full or not by checking the indicator light on the battery charger. In battery charging processes, chargers usually show a high current value. However, it will be observed that this value decreases as the filling process continues.
