One of the most frustrating thins in the world is when you have a flat battery. Everything seems to be going well in a day, and then suddenly, your car just doesn’t start. You try turning the key a few more times to be sure, and yet, it doesn’t budge. This can happen a lot if you take short trips, especially in the wintertime.
In the cold seasons, our cars are overworked. You go in, you turn the vehicle on, and you start the air conditioning, the lights, the wipers, heated seats, and they stay turned on as long as you are in the car. That drains the battery super-fast. Now, you might be thinking to yourself that the vehicle has an alternator and it will charge it. However, more electricity is leaking out of it than is going in.
Eventually, the juice will run out, and you won’t be able to start the motor. But, if you have a charger, that whole situation can be avoided, prevented and fixed. Now, there are many types of batteries, but the most common ones have a capacity around 48-amp hours. We’re going to dig a little deeper into how that’s important.
What this means is that when it’s fully charged, it can deliver one ampere for 48 hours, two for a full day, and so on. There are many ways to charge it when it’s empty, and the best range is between two and ten amperes. If you plug it in at two amps, it will take an entire day, and if you plug it at ten, the whole process will be much faster.

Why is that important?
Depending on the time you have at hand, you can pick the most convenient solution. Leaving the car plugged in overnight at two amps is okay, but anything around twenty amps is a grave mistake. That leads to overcharging and overheating. These two processes shorten its life as well as reducing its overall performance.
As for the question, is it better to use two or ten amps, there is a short answer. The short answer is ten amps because you get better results, as well as time. However, we will try to dig a bit deeper and see why that happens and how you can use the charger itself.
How to use and connect a car charger?
If you into your car and try turning the key, and not even the radio turns on, that’s a sure sign that your battery is dead. The most common reason this happens is because someone forgot to turn off the headlights. The thing to do in this situation is to take out the car battery carefully and place it on the ground. There is no way to turn the motor on, so the alternator can’t get any current inside it.
Now, you’re going to charge it manually. For that, you need a charger and you can go to any automotive store to buy one. Now, if this is your first time having a dead battery, the best solution is to charge it slowly, with 12 volts and 2 amps for several hours. When you buy the charger, you can see this setting, and it’s usually labeled green. You can read more on this link.
The device itself has a plug, as well as a red and black lead. Take the red lead and connect it to the positive side of the battery. There is a plus sign on that side. After you do this, take the black point and place it on the team with the minus. As soon as they are connected, you can plug in the charger to a socket. Then, leave it for a few hours and check on it periodically.
Before you start this process, make sure that the battery itself is out of the car. If you don’t do this, there is a chance to do damage the alternator. Most of the time, this happens in older vehicles, but it’s better to be safe than sorry. Now when the battery is almost fully charged, it will start to give off gas, and the cells will start bubbling.
However, if this process becomes violent in any manner, disconnect the charger immediately. That is a sure sign of a defect, and you need to bring it to a professional to review it. Or you can get a new one altogether. The same thing goes if any of the cells start giving off gas and bubbling before the rest.
When the whole process is done, you need to disconnect everything and place the battery back in the car. However, don’t try to take out the leads before you unplug the charger from the socket. If you do this, the leads can create sparks, and that can ignite the surrounding gas. You don’t want to create an explosion from merely charging a battery.
A few final words
No matter if you pick two amps or ten amps, there are a few precautionary steps you need to have in mind. Since you will be working with electricity, you need some protective gear. Goggles are a must as well as a rubber or latex glove. Make sure that you’re wearing something with long sleeves because there is always the risk of electrocution.
And, since there are chemicals involved too, make sure that you’ve opened a few windows and doors in the garage. If you’re out in the open, there is a lot of fresh air around that will nullify all the gasses coming out. Additionally, make sure that you take a look at the user guide or manufacturers manual. There you can see the capacity and calculate the amp hours by yourself.
For example, if the reserve capacity is 80 minutes, then you need to multiply the number with 0.6, and you will get 48 amp-hours. This will help you calculate the time required to charge, and based on what you plan to do in the day.
