Buyers Guide

What to consider before buying a car battery charger?

Battery type

Not all chargers are versatile and can charge all types of batteries. For instance, a gel cell battery commonly requires an individual charger, while other batteries, including lead-acid or AGM can be served by the same maintainer. So you should think carefully before making the final purchase decision. If you store a variety of unlike batteries in the garage, it is more reasonable to go for a small car battery charger that is capable of maintaining them alone.

Battery rating

Battery rating is calculated in ampere-hours which indicate how long a battery charger is able to sustain the current before getting fully discharged. An average car battery is rated at 50 amp-hours. For instance, if you have a 25 Amp charger, the charging time will be 2.5 hours until the charge is complete. But if your battery is deep-cycled with the rating of 200 amp-hours, the same charger will take 10 hours to revive the battery from a dead condition.

So you should know in advance which battery rating suits your batteries best so as to minimize the charging time and get the most benefit from the charger.

Auto battery working principle

Based on all the auto battery charger reviews above, you must have noticed that any smart charger is underpinned by the same working principle. The point is to provide the electric current to a car battery which in turn gives it to the engine making the car move. When batteries approach self-discharge, the alternator is required to do the battery job too. This leads to premature alternator failure. If you are not ready to risk your vehicle, here is only one thing to follow – you should always carry a good battery charger or booster in the truck.

Why is a battery charger more reliable? The average battery capacity is about 48 amps-hours, which means that it can supply 1 Amp to the engine during 48 hours or 6 Amps during 8 hours when the engine is completely dead. A charger consumes AC power and then transforms it into DC power to provide for the battery. The DC current is always supplied at a low voltage, especially when it is the dead battery that is going to recover. High voltage is prohibited at the first stage of charging as it may entail the increased formation of hydrogen gas which heightens the risk of explosion, especially when the battery is not tolerant to overcharging and overheating.

The ideal approach to dealing with dead batteries is to use a charger working at low voltages because fast charging is never safe and best to be avoided under normal circumstances.

What is the charging time of a car battery?

Normally, the charging time of an auto battery is dependent on the amperage of a charger. If the charger has high amperage, you can expect a fast charge of the charger, while the charger with low amperage makes you wait a little but instead provides a safer and less risky charge.
You can use chargers with different amperages to provide energy for your batteries.

2 amps

A 2 Amp battery charger will need about 24 hours to get your battery to full charger. This level of amperage is fit to situations when you need only to maintain your battery.

4 amps

A 4 Amp battery charger works somewhat faster and lets you charge the battery within 12 hours. It is yet not enough for quick charge, but this type of chargers work best for small batteries like those in motorcycles.

40 amps

This amperage is what you can see in any top rated automotive battery charger that acts as a maintainer and booster at the same time. High amps are ideal to quickly start a 6L engine or charge a battery with a large capacity in less than an hour. The only dangerous thing to remember about high-power chargers is that you should not apply them for long periods of time because some batteries are not programmed to deal with overcharging.

How to provide a fast charge to a car battery

There are two main factors that define the charge time of any battery.

This first one is how much a battery has been discharged. On average, a few hours are enough to get your battery to full charge, but if you are going to charge a dead battery, it will take more hours to bring it to normal condition. Keep in mind that fast charging rates are not recommended because they shorten the battery life span.

The other one is the amperage of a charger. As you’ve learned above, high amps lead to faster charge and allow charging batteries with any capacity quite rapidly. However, a high-amp charger may be dangerous for low-quality batteries. If you opt for the best portable car battery charger though, it is able to limit the voltage and amperage after the battery enters floating mode, which makes the charging process entirely safe and highly efficient.

Can an auto battery charger start a car engine?

A car battery charger is not able to give a jump start to your car because of low amps. Normally, a car needs the amperage between 36 and 72 amps to recover quickly from self-discharge. Battery chargers usually have lower amps that are too weak to return a dead battery to normal operation. The amount of current it is able to supply in a short time is not sufficient to jumpstart a car.

In short words, a smart car charger is user-friendly and completely safe for the user but still is not aimed to boost engines affected by self-discharge. If you are in search of a device to boost a dead engine, stick only to starters that can maintain electrical equipment and also provide a jump start if necessary.
