The Best Car Battery Charger
Which car battery charger to buy to avoid risk of staying on foot? Which are the most efficient charge maintainers to prolong battery life and not run risk of having to replace it? Let’s find out, which are the best battery chargers for cars more efficient to load and maintain, how to choose the most suitable for your needs and what features to evaluate at time of purchase.
The Car Battery Charger is a device that can recharge a car battery without changing or replacing it. In winter, in case of long periods of non-use of the car or, if the battery begins to show signs of failure, it is advisable to keep a good charger in the garage or in the trunk to avoid unpleasant inconveniences caused by a machine that does not start due to battery empty.
A good charger basically has to do two things: provide a full charge reasonably and protect the car battery avoiding overloads. The car battery charger is divided into fixed, portable, maintainer, and booster, each with different characteristics, prices, and specific purposes. Let’s see how to choose one that best suits your needs and vehicle.

How to choose a car battery charger: Types and Characteristics
To choose exactly the best car battery charger, the parameters to consider are vehicle type, type of battery, amperage, fixed or portable, battery charger, or maintainer.
Type of vehicle
Almost all cars have a 12-volt battery, motorbike batteries can be 12 or 6 volts, and scooter batteries are generally 6 volts, while vans and trucks have 24-volt batteries. Depending on the vehicle you are loading, check the charger’s compatibility.
Battery Type
Does your vehicle have an AFB battery, gel, nickel-zinc, lead-acid? The exception is made for gel batteries, which require dedicated charger models. Can safely load all other types with a normal car battery charger.
Amperage
The size of a car battery is measured in amps/hour. Generally, a car battery has about 50 amps/hour, so it will be advisable to opt for a model that allows you to recharge it in 6 hours fully. It will be enough for faster reloads to buy a car charger from the larger amperage (to calculate the approximate charging time, divide the number of amps/hour of your vehicle’s battery to those of the charger, adding to the final result 10%).
Portable or fixed charger
There are portable car battery chargers, simple to keep in the car, or fixed chargers, generally larger and more suitable for a garage or used in the workshop. The portable models do not require a connection to the current to start up and can be equipped with handy accessories, such as, for example, the tester or compressor for tires.
Instead, the fixed models must be connected to an electric current to work. So if your goal is to leave the car in the garage for winter, the fixed charger may be a better choice if you want something that can help you even when you are away from home, in case the car is broken down, or if you are traveling for work, a portable charger is the best choice.
Safety and Certification
Models that are too cheap and too cheap should be avoided, especially if they declare a very high amperage, as they will hardly be reliable. A parameter on which to base is the CCA (or cold start evaluation), which indicates the amount of energy needed in cold conditions: the frost conditions make it more complicated to start the engine using a car battery charger.
It is better to always opt for quality and certified models, with a good evaluation of cold start (CCA) and long cables to guarantee a clean job without too many obstacles.
Car Battery Charger – Maintainer
The car battery charger maintainer is a type of battery charger essential to keep the battery charge alive. It is generally used in your vehicle’s maintenance phase and is useful, for example, to recharge the battery on the night before leaving for challenging car trips. The function maintains the charge level but cannot revive the battery in emergencies.
Booster Charger
Also known as Jump Starter or Car Emergency Starters, these car battery chargers allow you to connect a battery to terminals. As a result, the car battery charger booster will be compact and manageable, cheaper, and more rapidly in emergencies.
