6 Best Chargers for Car Batteries

The problem of the modern world in the lack of time and widespread vanity has found its rightful reflection on such a remote topic as ensuring a stable recharge of batteries. Imagine that when you wake up early in the morning to catch an important meeting in time, you find an unpleasant situation – literally overnight the car’s battery has been discharged to zero. It is in such situations that there is an urgent need to have a portable charger that can reanimate even a hopelessly sown battery.

On the thorny path of choice, the potential buyer has to face many pressing problems, the main one of which is the abundance of competing models and the companies that produce them. In order to simplify the choice as much as possible, but leave the right to make a decision, we have created for you a rating of the six best automatic and manual chargers for a car battery. The following items became the criterion for selecting and forming the final list of goods:

  • the opinion of authoritative sources, professionals, and experts;
  • customer feedback on the experience of using a device;
  • technical characteristics, performance parameters, and availability of operational “chips”;
  • the legitimacy of the ratio of value and nominal quality.

Best Automatic Battery Chargers

Automatic chargers are an “intelligent” current supply system. In the absence of any load on the terminals, the charging process does not proceed, but if the battery is connected correctly, a long process turns into a distributed current loop.

As the battery becomes saturated, the charging current decreases, thereby not causing the electrolyte to boil, which in the case of manual charging can lead to an explosion. As soon as the process ends, the voltage is automatically equalized to the level of charge support.


The most simple and at the same time practical charging unit, working in automatic mode with lead-acid batteries. This model is very different from the competitors in the rating: the ascetic appearance of the front panel contains only two indicators – no switches, no knobs of the regulator and a display announcing the magnitude of the charging current. There is a lamp for controlling the charge of the battery and, in its essence, a diode of the activity of the proceeding process.

As for charging, the ORION PW150 is not able to pull a discharged battery to zero, and can only help to survive to someone who is an actual “death”. On this, his talents are exhausted, but simplicity still won a bit of popularity among users.

  • ease of use;
  • low price;
  • a good working resource.


  • to the outrageous simplified mode of operation.


One of the representatives of a small cohort of chargers, working not only with 12-volt but also with 24-volt batteries. Despite its unimaginable dimensions, it is quite a powerful device capable of charging electrolyte batteries in realities of industrial scale. If you follow the trend of purchases, it becomes clear that for the personal use of the device buy about 20% of consumers, while the rest are representatives of service centers, repair stations, and maintenance of cars. However, the high quality of the assembly and the covered operating range significantly adds SMART-POWER SP-25N Professional in price, which means that budget users are already eliminated at the stage of quick selection.

  • compact and productive;
  • elementary, intuitive control;
  • presence of moisture-proof case, charging indicator and digital display.


  • high price.


Not too compact expensive device for automatic recharging of high-end car batteries. It can easily cope with the gradual “refilling” of batteries with a capacity of 100 Ah. The start of the charging process takes place at a nominal current value of 6.5 A. Gradually, by processing the received data from the battery status terminals, the device itself selects the optimal mode for these conditions, either increasing or decreasing the ammeter readings. Another important factor is the availability of a notification system about a fault that has occurred, which makes it much easier to control the process of operation.

QUATTRO ELEMENTI i-Charge 10 is used not so much in the home as in the service environment, where its full potential is revealed, starting from charging low-power batteries and ending with impressive batteries.

  • availability of a fault warning system;
  • equipment control panel touch screen;
  • low power consumption;
  • a successful design, effectively cooling electronic units from overheating.


  • low maximum current supply (10 A);
  • not too low cost.

Best Hand-type Chargers

Punching chargers for resuscitation “tightly” the old batteries. They are characterized by instantaneous and stable transmission of a current of a certain force to the terminals, which is perceived by the battery in small volumes. Gradually the battery “comes to life” and begins to take the current in full portions.

The main drawback of such chargers is the need for constant monitoring – from excess energy, the electrolyte in the accumulator begins to boil, which often leads to an explosion of the battery itself and entails damage to property and health. They cost an order of magnitude less than automatic analogs, but for security reasons (if there is no time to monitor the process of charging), it is better to resort to buying an automatic device.


As a matter of fact, the Chinese brand under the proud German name, letting out an inexpensive in the form of unpretentious charging units for automobile accumulators. In fact, nothing new demonstrates this copy – it meets the standard requirements for recharging 12-volt batteries, and does it quite in good faith. Unlike many much more serious models in the KOLNER KBCN 4 is sewn an additional block of protection against short-circuiting, so the random transfer of the terminals will not be intractable. The charge indication is made by means of distinguishable LEDs, both at night and during the day. The only serious inconvenience of the device is the need for periodic monitoring – from excessive current saturation, the electrolyte can simply boil.

  • the presence of a short-circuit protection system for the terminals;
  • acceptable durability;
  • A convenient form, including a handle for carrying.


  • the charging process requires periodic monitoring.

ZPU 135

The most powerful starting-charging transformer device with a manual type of control, the potential of which can suffice for the “breath of life” in an empty capacious battery. The maximum charge current reaches an impressive 13 A, and the starting current and even more – a one-time ejection of 140 A (for 10-15 seconds, for a simple estimate, it can instantly “boil” the electrolyte even in a battery with a capacity of 140 Ah (and 12 and 24-volt ones.) Only a small number of consumers prefer to use home appliances for this device, which is much more common in car repair shops, services and transport shops of private and state-owned enterprises. I in the absence of protection from the occurrence of a short circuit – when fixing the terminals it is worth to be particularly attentive.

  • high rated power of the start-up and normal charging mode;
  • elementary control;
  • attractive cost.


  • the probability of short-circuiting the terminals and the failure of the device.


A modern system with a pulse voltage converter, clad in the echo body of the 90s. The model is so practical that the first advantage can be called simple and intuitive manual control. The rest of the manipulations are simply superfluous: Sonar UZP-210 does everything itself, in automatic mode. This is a clear example of a combination of two conceptually different ways of management, which gives excellent results. Charge modes two – with a maximum of 12 A or 6 A for different types of batteries. Charging proceeds according to the classical scenario of the automatic method: quick charging, equalization of the current supply to the standard value, as the battery becomes saturated, it switches to the buffer mode and stabilizes the voltage at the saturation level.

  • an impressive short-time starting current (200 A for one or two seconds);
  • compactness;
  • automatic charging with manually configurable parameters.


  • not detected.

How to Choose a Good Charger

To select the ideal charger in terms of operating parameters and durability, you should pay attention to a number of important criteria:

Appointment:  Devices are divided into three types:

  • starting, whose task is a one-time resuscitation of a battery to obtain a momentary result;
  • Chargers intended for a long, but full recharge of the battery;
  • start charging – a combination of the first two types of devices, serving as a universal apparatus.

The Choice Depends on Your Personal Preferences

Charging method: This category has only two methods: automatic, in which the voltage is regulated by the device as the battery charge increases, and the classic (manual), requiring periodic monitoring of the process by the user.

Modes of supported voltages: A parameter that determines the typology of rechargeable batteries. So, some devices are designed to charge unpretentious 6-volt batteries, standing on the motor transport, while others feed a powerful 24-volt or more averaged battery at 12 volts.

Availability of additional function: Some manufacturers tend to add distinctive features to their products, whether they are original LEDs, battery power modes (Boost, impulse charging, etc.) or equipping the device with a drive capable of storing the results of the charging sessions.

We also recommend paying attention to the completeness of the equipment, the length of the regular wires with power terminals and, in fact, the total cost of the product.
