Buyers Guide

What is the best battery charger?

It is not an easy question, but you can find the right answer by thinking of the following:

Battery type

Some battery chargers are versatile and are able to charge lots of battery types, including AGM, flooded, deep cycle, etc. Others are strictly specific and can maintain only one battery type. This means that before buying a battery charger, you should envisage which batteries you are going to maintain or recover. If you hook up a charger with non-compatible equipment, you risk impairing either or both of them.

Power capacity

High power capacity is a common characteristic of energy-consuming equipment, for example, engines, while low capacity is usually typical of small devices. Enormous battery capacity is not always an advantage when you deal mostly with equipment that needs small amounts of charge. Extremely strong charging current may lead to battery breakdown or damage the chemicals inside a battery. Commonly, the maximum charge current should constitute 20% of the battery capacity.

Multi-bank chargers

A multi-bank charger seems very appealing in terms of usability, but you should be considerate to set the smallest size of all battery chargers to prevent overheating or not to slow down the charging process.

How to apply a car battery charger?

The battery chemistry is prone to produce hydrogen that tends to explode under certain conditions. To avoid such a scenario and be able to exploit the battery safely, stick to the following rules:

  • Do not apply one battery charger to all batteries available at home.
  • Always read the user’s manual before using a charger. You should have a clear and correct image of how it is supposed to operate.
  • Do not forget to take away battery cables from terminals.
  • The charger should not be plugged in if it is not charging.
  • Check that a positive cable gets connected to a positive terminal. Apply the same principle to the negative one.
  • If the charger is not deactivated automatically, make sure you set the time of charging.
  • Turn off the charger after the battery has reached full charge.
  • Always detach the cables after you no longer need to charge the battery.

How long to charge a car battery?

If we talk about the best 12 volt battery charger, the only factor defining the time of charging is the amperage of the charger you’ve bought. High amps are an indication of fast charging, while low amps will make you wait a little to have your battery fully recharged.

Here are a few possible amperage options.

40 Amps

This level of amperage suffices to instantly start a car. Charging will last no more than 2 minutes. This type of charger is an excellent choice for giving a battery a powerful and quick charge. Those who do not like waiting will find this charger of much use but beware of overcharging.

2 Amps

This amperage is not intended to charge rapidly, so it will take 24 to 48 hours to have your battery charged. This type of charger is fit to those users who try to maintain a battery without boosting it.

What’s an average lifespan of car batteries?

The life service is mostly defined by power capacity and initial durability. A car battery is expected to serve between 5 and 6 years under ideal conditions. In reality, however, there are some factors that affect the battery operation and may shorten its life service. In the end, car batteries commonly die after 2-3 years of active use.

These bad factors are high humidity and extremely cold or hot climates that incite changes in chemicals. However, you can alleviate the detrimental impact of these conditions by preventing the battery from excessive sunlight exposure as well as controlling that the battery is never left plugged in after full charge has been provided.

What happens to an overcharged battery?

Many novices make the same mistake when dealing with a powerful battery starter. They are too excited to revive their dead battery and often forget to stop charging at the right moment, so killing their battery anew.

Overcharging affects chemicals which start heating up the battery case. As soon as the case is ruined, hydrogen and oxygen are able to penetrate it. At this point, the battery becomes a real bomb that can explode in the event that the smallest electrical spark takes place around.
Luckily, the explosion is a very rare scenario in real life, but the battery deterioration is a typical one if you do not disconnect it from a charger timely.

To avoid this experience, my recommendation is to employ only the best rated battery charger (like those you’ve read above) and regularly monitor the battery charging status while it is plugged in.
