If you have a dead battery at the road side and you try to resolve the issue with someone who can just “light your car up”, this just doesn’t work. In reality, the most of novice drivers encounter such situations regularly. How can you prevent exhaustion of both your car battery and nervous system? It is simple: the battery must be monitored and a charger must be on hand. Here is why you should use car battery charger and which one you should go with:

In normal mode, the battery is recharged by the generator during the journey, however, if driving short distances around the city, this is certainly not enough to charge it. It is recommended that city motorists charge their batteries every six months at least, or else they risk being stranded at some point without a car. The onset of cold weather should coincide with one of the exercises. Take this example: you switch on several powerful items at the same time (heated seats, windows, mirrors, headlights). The generator power may not be sufficient to support a large number of energy guzzlers in traffic jams at low engine speeds.

Also, you may need to recharge your car if you leave it idle in the cold for a long time, for example, when you take a business trip or if you do not drive at all during winter. While it is better, of course, not to allow deep discharge, since it is harmful to the battery, and many cycles of deep discharge can cause the device to fail. When all else fails, it is charging that can help you restore its performance.

Choosing a Car Battery Charger

The first parameter that must be considered when choosing devices for the battery is their purpose. Batteries can be charged, started, and recharged. Basically, everything is clear here: the first group performs only charging functions, the second group starts the engine, but a third group performs both. Besides portable chargers for batteries, there is also a portable battery charger if you are trying to start the engine with a dead battery, for example, in the “deaf steppe”, where outlets are not available.

It seems sensible to buy starter-chargers even though they are more expensive. Such a device, however, requires power to function as a starter. For homeowners with an electrified garage or house, it is quite possible to purchase an automatic starter, for everyone else, a regular car battery charger will suffice.

A car battery can also be charged by a transformer or pulse charger. Due to their transformer and rectifier circuits, the latter are often larger. It is more convenient to use pulsed memory as a household spare several times a year: it is more modern, reliable, and compact.

What Else to Pay Attention to?

The next thing to consider when purchasing a charger is the current that the process uses. When the battery is configured at its maximum capacity, 0.1 * C is the optimal setting. A charging current of 6.2 Amperes should be sufficient for a 62 Ah battery installed in your car. It is also possible to use less power, but the charge will take longer.

Fast charging is available in many types of car battery chargers today, such as Boost. A jump starter is used when the battery needs to be charged quickly enough to start the car. Chargers in this mode give out a higher charging current and the process is accelerated because a sufficient current is supplied to the battery. While this can achieve the desired result, it accelerates the charging process because a higher current is being offered to the battery. The battery can be sufficiently charged for the motor to start in 15-20 minutes in this mode. In spite of this, it is not advisable to use this mode often since it simply harms the battery.

Even in Boost mode, the battery should not receive any more power than 30% more than the standard value.

When buying a charger, we should go for one with a slightly higher charging current than the optimal calculation. If the memory and battery work well together, the memory will work to the maximum of its capabilities. Even the simplest chargers can be adjusted manually; most, however, can function in automatic mode as well. These are one of the best chargers for car batteries that you can find.

If you accidentally mix up your terminals, you usually have protection against incorrect connection with automatic memory. With them, it’s as simple as connecting and turning on (or using a button) and waiting for the process to complete. The electronics themselves regulate the power so that it’s always at the optimal level.

Desulfation Mode

As we all know, this is one of the most important functions of car battery charger, which should not be overlooked since under adverse weather conditions, or after deep discharges, sulfates of sulfuric acid are formed on the battery plates, which reduces the density of the electrolyte. Consequently, the electrolyte capacity will also decrease. By using the desulfation mode, you can recover this characteristic.

The charge-discharge cycle used here is special. The whole structure works well for several days once the battery is charged and the charger is in desulfation mode. Battery capacity is restored following the destruction of the sulfates and cleaning of the plates.

A car battery must be charged when there is a voltage drop across the terminals of less than 11.2 volts. The battery can still start the car even with such a charge, nevertheless, when it is left unattended for a long period of time at a low voltage, sulfation processes begin, which lead to the loss of battery capacity. Hence, it is essential to continuously recharge the battery while the car is parked or in the garage over the winter. Better yet, remove the battery, keep it in a warm spot, and remember to maintain its charge. Direct current or pulsed current is used to charge the battery. It is usually recommended to use a charge current equal to one tenth of the battery capacity when charging from a source of constant voltage.

Final Words

We hope that after reading this material, you have gained an understanding of what a vehicle battery charger is, how to choose one, and how to use one.
