It often happens that we carelessly forget to turn off headlights or wipers or don’t close the door tightly and our accumulator is completely discharged. Every car owner can agree that such situations arise at the most inopportune moment. Nevertheless, if you have an emergency power pack, your accumulator will never ruin your plans. Our article will help you figure out the main charger types and choose a matching device for your needs.

The main technologies

Today the industry offers one leading type of power pack technologies. Inverter (or “smart”) units charge the battery through pulses. Unlike outdated transformer models, inverter devices operate at higher frequencies. They are equipped with a microprocessor instead of the transformer. That is why they are relatively light, compact and convenient to use. Such power packs offer automation of the entire process and have reliable short circuit protection.

Some inverter models have the memory function, which means that the non-volatile memory stores all the parameters of the last charge. The next time you turn the unit on, the current magnitude and time are already adjusted. This feature is very convenient and saves much time.

Some points to concern when purchasing a suitable power pack

• First of all, you have to determine your accumulator type. Modern batteries come in three categories: WET, GEL and AGM. The difference between them lies in the forms of electrolytes (liquid, gel, impregnated fibreglass). Most cars are equipped with WET batteries. The other accumulators are sometimes used for luxury class vehicles. Standard lead accumulators are ideal for WET batteries, whereas GEL and AGM units are too sensitive to charging current and voltage.
• Battery voltage is another critical feature. Most vehicles usually have 12-volts accumulators. Our Triace online store offers a range of universal chargers operating in several voltage modes, making it possible to toggle between 12 and 24 Volts. These Sealey devices are perfect for servicing cars and trucks. They are used both for small and large vehicles, agricultural, mine and open-cast equipment.
• Another relevant characteristic when choosing a power pack is the charging current, which is selected depending on the capacity of your battery. The current should total 1/10 of the rated battery capacity. For example, if your battery’s capacity is 65 Ampere-hours, the optimal charging current for your accumulator is 6.5 Amps. Weaker current will not harm your battery, but the charging process will take much time. Moreover, in the boost mode, the charging current should not exceed the optimal by 30%. The maximum permissible charging current for the same accumulator with a capacity of 65 A-h is 8.45 Amps.
The main thing when choosing a power pack is to select a device with an equal or a bit higher charging current than that calculated according to the abovementioned scheme. In this case, the device will not work at full capacity, providing a smooth and uniform charge at a fixed voltage.
• Some power pack models are appointed with a special boost mode for quick charging. This mode offers an increased charging current, which is enough to start the engine. The battery is charged in about 15 minutes, but it is not recommended to overuse this mode.
• In addition, some chargers are equipped with extra functions such as checking the battery charge level, diagnosing the general battery health, testing the generator. You should also pay attention to the versatility of the device, as there is always a possibility that you’ll need to charge several accumulator types.
• The modern market also provides professional chargers for car service shops, which offer the ability to charge multiple batteries at the same time with a parallel or serial connection. However, this feature is hardly useful for home use.

Final Thought

There is no doubt that it is better to give preference to the power packs with the highest functionality. Triace shop offers reliable heavy-duty power packs providing over-voltage protection, efficient power transfer for most battery types. If you still have some questions, our specialists are here to choose the best device for your vehicle.
