Let's figure out how to choose a start-up charger

Sometimes motorists face the situation when the battery is completely discharged, and for its charge there is absolutely no time, and you need to go right now. In this case, a start-up battery charger can help . Such a mechanism is able not only to charge the battery, but also, due to the high starting pulse of the charged current, to start the car with a completely discharged battery. This article is devoted to how to choose a start-up charger, on which parameters it is necessary to pay attention.

Technical features of units

The starting-charging device for the car differs from chargers with current-carrying elements of increased power, which can ensure a reliable and durable operation of the device. Early models of such mechanisms contained a transformer, which adversely affected the electronics of the car. This forced users to disconnect the circuit feeding the on-board electronics before starting. Modern devices are built on inverters, which replaced transformers (now there is no need to disconnect on-board systems), accordingly, the dimensions of such start-up devices decreased. Also devices are produced, where microprocessors are used instead of inverters, which optimize the charging process, provide monitoring of the battery status and battery safety.

Starting and charging devices protect on-board systems from polarity reversal, overheating, short circuit. In addition, the protective functions of the device in question are also the battery recovery mode and the mechanism shutdown at full charge. All this contributes to simplification of operation and increase of car safety.

How to choose a start-up charger?

This question is asked by many novice motorists. Let's figure out what to focus on when choosing such a device.

First, it is necessary to decide whether you need a device to start a power unit or just a simple charger. After all, the price of starters is much higher. If you have already made a decision, then consider how to choose a start-up charger. The next step is to determine the capacity of the battery, which will need to charge the device. The device must have a workload exceeding this parameter. For example, if the battery capacity is 170 Ah, then the selected device should have a rated current of 18 A and above. Most cars are equipped with batteries from 55 to 70 A. However, when choosing a starting-charger, you need to consider that such a device can serve its owner for more than a decade, so the power of the device is recommended to choose with a margin, in case the car owner will change the car On an off-road car or a minibus. Batteries of such vehicles are characterized by an even greater capacity. Accordingly, if the charge is bought, that is called, butt, then you have to change it.

Next, you need to determine the type of device: which is better to buy - with self-powered or networked? "Autonomists" are able to work even in the field, because they are equipped with a powerful battery, and the network needs a supply voltage of 220 V. Also, when choosing starters, you need to know that they are produced for both 12-volt and 24-watt batteries.

Conclusion

We discussed how to choose a start-up charger, but remember that these devices work with large rated currents (more than 100 A), which is quite dangerous. When using this device, you must follow the safety rules and follow the manufacturer's recommendations. This will allow to successfully operate the device and help to avoid injuries and breakdowns in automotive electronics.
