A dead car battery is something that we do not want to have! Nonetheless, it is inevitable, especially if you are the type of person who often forgets to have it checked. Such a situation can be frustrating! Once it is drained, have it recharged the soonest possible time. That being said, you are possibly curious about one thing – how long to charge a car battery.
In the rest of this post, we will let you know what exactly is the duration that is required by the battery to be fully-charged. We will also tackle other things, such as tips when charging your battery, making it possible to optimize its performance and to have an assurance that it will remain functional for an extended period.
How Long to Charge a Car Battery
Unfortunately, there is no single answer to this question. This will depend on a number of factors, such as the quality of the battery and the charger that you are using. The age and capacity of the battery will be primary determining factors.
In the case of most of the chargers that you can find on the market, they have two amps. Typically, for a 48-amp battery, it will take about 24 hours before the battery is fully-charged, provided that you started when the battery is dead.
If possible, invest on a high-quality charger, which will provide a guarantee that the battery will be fully-charged without the need to wait for an extended period. You should also determine the right amperage of the charger and see to it that it is suitable for the battery where it will be used. A higher amp will shorten the time that is needed for the battery to charge.
There are also situations that can lessen the time that is needed for the battery to recharge. For instance, if it is well-maintained, which means that it has the right level of water and sulfuric acid, charging time will be quicker.
The choice of charging method is another thing that will have an impact on how long it will take before a battery can be fully-recharged. Jumpstarting is the quickest way to charge your battery, but it is lacking in terms of efficiency. Advanced and automatic battery chargers are the best, although they can be quite expensive.

Why Your Battery Drains
Aside from talking about how long to charge a car battery, this post will also uncover some of the reasons why the battery is drained in the first place. It is important to have an understanding of these things as it will help to prevent being in an unfortunate situation of having a drained battery.
Among others, one of the most common reasons for the failure of the battery is when you leave the lights turned on. You might be in a hurry getting out of your car and hence, it did not cross your mind that the lights were not turned off.
More so, if you have lots of accessories in your car, they can also contribute to the failure of your battery. Using the radio and entertainment systems will cause the battery to drain because it is their source of power.
The battery will also fail if it is poorly charged. This can be because you do not know the right techniques, or simply because you are using a charger with an inferior quality.
So that you will not be surprised with a drained battery, you should invest not only in a good charger, but it a hydrometer as well. Make it a habit to always check the capacity of the battery and charge it when it is below what is necessary.

Tips for Charging your Car Battery
Before we end this post, let me give you some practical tips on how to make the most out of your car battery, which will also be instrumental in the improved performance of your car and overall, a better driving experience:
- Before charging the battery, take the time to clean the terminals. If you can see whitish powder covering the terminals, do not attempt to touch it. It can burn the skin. Rub it with sandpaper and thick cloth. When the terminals are clean, charging time will be quicker.
- In most types of batteries, you will see cell caps on the top part. You have to remove them before you start charging. During the process of charging, gases will be generated and they will not be able to escape if the cell caps are not removed.
- Before charging the battery, you also have to add distilled water first to the level that the manufacturer recommends. Be sure to not overfill it with water. In the case of batteries without cell caps, this is no longer necessary.
- Read and understand the instructions from the manufacturer. There are lots of online resources that will tell you what to do, but the specific steps involved will still depend on what the manufacturer suggests. Different types of batteries may have different charging requirements.
- A charging schedule should be established. Make it a part of routine maintenance. This will lessen the frustration since you are sure that the battery is kept at a good charge. Charging should be done more often when you live in a place that is extremely hot.
