Buying Guide – How Do I Pick a Good Portable Car Battery Chargers?
Thanks to a battery charger, you will be able to restart your vehicle that has been idle for months (or years) without difficulty. If you are interested in this kind of product, but you are not sure which model to choose, then this buying guide for the best battery chargers will help you in your decision-making.
Battery charger type
How to buy a better value-for-money battery charger? The best solution would be to use a price comparison so that you can evaluate all the offers on the market. But long before you get to this step, you first need to determine what type of battery charger you need.
A distinction is therefore made between simple chargers which are equipped with a transformer and a rectifier diode bridge. They have the capacity to carry out a type W charge, according to the DIN 41 772 standards, and are sometimes equipped with a switch that allows choosing between 2 charging regimes: a slow charge or a fast charge. Simple chargers are cheaper, but it is nevertheless necessary to monitor the load because the output voltage depends a lot on the voltage supplied by EDF (or another energy supplier in the country).
Then there are the automatic chargers. In addition to a transformer and a rectifier diode bridge, they consist of an output voltage limiting circuit. Charging therefore does not require monitoring, as the voltage will automatically be limited to approximately 14.5 V for chargers intended for maintenance-free products.

Capacity
Knowing the capacity of your vehicle’s battery will help you decide where to buy a new battery charger. This capacity corresponds to the energy that your battery can restore in 20 hours of use. In other words, it is the total energy that it is able to restore. It will meet all the needs of energy-consuming elements. The value of this capacity is expressed in Amperes/hour (Ah).
The connection with your battery charger? The model you choose will need to be able to load this capacity. For example, if you have a battery with a capacity of 60 Ah, then you will need to purchase a battery charger that has at least the same capacity, i.e. 30 to 120 Ah, for example.
Battery voltage
Choosing a battery charger model according to the voltage of the battery to be charged is also a tip that you should consider. This voltage is expressed in volts (V) and you just need to match the voltage of your battery with that of your charger. If your car battery has a voltage of 12 V, then you will need to purchase a 12 V battery charger.
You might want to charge a 12-volt battery, and another with a different voltage (6 volts for example). This is not a problem, as several brands offer models capable of charging 6-volt and 12-volt batteries. So you just have to choose the voltage you need.
Security features
Car batteries contain toxic materials. A fault or failure can be very dangerous. You, therefore, need to have specific equipment for preventing breakdowns, namely:
- Anti-spark clamps to avoid generating a spark of contact between the two terminals together.
- Reverse polarity for those who tend to connect the wrong cable to the wrong side of the hardware.
- And automatic voltage and amperage detection which can prevent overheating when you charge it.

Other features to consider when researching
In addition to the basic technical characteristics, it is also necessary to take into account, the length of the jumper cable, the quick start function, the load of the Trickle, the diagnosis, and its maintenance mode.
How to use a portable battery charger?
The battery is one of the centerpieces of a car or any other locomotive tool. For this equipment to be functional at all times, it must be well loaded. This is the importance of a battery charger. Those who are used to driving a vehicle cannot do without it. Its use remains practical and can troubleshoot at any time. But in order not to be mistaken in its use, here are some good useful gestures.
How to Use a Portable Car Battery Charger| Video Explanation
Choose the place to recharge the battery
Before recharging your battery from the charger, it is necessary to choose a ventilated place. Indeed, when recharging, the battery can release harmful and flammable gases. It is also necessary that the loading takes place in an environment which does not contain flammable products and a significant source of heat.
Disconnect the battery
At the beginning of the power supplies, it is better to completely disconnect the battery. This will prevent other equipment plugged into it from being damaged. Also, before recharging a car battery, make sure you have removed the caps from it. This is essential for the escape of vapors and gases.

Connect it correctly
First of all, it is necessary to carefully read the characteristics of each material. This means that the charger must be compatible with the properties of the battery to be recharged.
It is advisable to always rely on the manufacturer’s manual. You will thus be able to know the voltage at the terminals and the intensity to be applied in the event of recharging. In general, you must connect the terminals: positive to positive (+), negative to negative (-).
Protect yourself on handling
Charging the battery can cause some inconvenience to your health. For this, it is necessary to wear protection such as glasses and gloves.
Adopt good habits
When you leave your vehicle idle for too long, it is best to charge it with a battery charger regularly. The use of a charger of this kind is still desirable even if you do not drive a lot.
In some cases, it is necessary to charge the battery while driving to allow your battery to function better.

Respect the operating mode of your device
You should be aware that traditional models require a shutdown at the end of each charge, and therefore should be closely monitored during the process. Smart chargers, on the other hand, will turn off by themselves when the battery is full and activate automatically otherwise.
Respect the voltage level
Take care to put your charger at the right level in order to preserve the condition of your battery. The charge provided by your equipment must stop between 2.5 V and 2.4 V per cell. In the case of a 6 V battery, select a load between 6.75 V and 7.2 V. For that of 12 V, choose a load between 13.5 V and 14.4 V. Leave it several times. The charger will let you know when charging is complete.
Is it possible to charge a dead car battery?
Usually, it is the circumstances of “death” that determine whether or not the hardware can be recharged. If a battery has been stored for a long time, or if you’ve left your car’s headlights on all day and night, you can probably recharge the battery (although it may take some extra work).
However, if a battery has been repeatedly discharged and recharged, or has simply stored and discharged electricity for many years, it may simply have reached the end of its life cycle. Proper maintenance, a good charger, and a little know-how can maximize the life of a car battery. Despite this, no battery lasts forever.
