Who doesn’t know what batteries are? Even though now we have advanced technology where we can recharge things and get new energies, it does not mean that batteries are completely out of business. After all, there are some things that still need batteries to be able to be used (such as cars and remote TVs). But have you ever notice the terms they used when you purchased a battery? There are so many unknown terms that we do not understand, and Ah is one of them. Here, we will discuss all what Ah is in battery, what its meaning is, the quality, and improvement.
When people talk about Ah in a battery, it means that people are talking about the capacity of the battery. Ah represents the discharge the battery gives to the object and the amount of discharge it gives overall. In a simpler term, Ah is the amount of time the battery will be able to give the object the energy it needs. Another term for this is the “capacity” of the battery.
However, you should not mistake Ah to Amp Hour. although the two sound similar, they are actually quite different. If you know that a battery has 5Ah, it does not mean that it will give a 5amp device energy for one hour only. Amp hour can only be found out when you know factors such as:
●The temperature of the environment
●The “hour rate” of the battery
●The final voltage of the battery
●The type of device the battery powers
From here, we can see that amp hour and Ah are vastly different and should not be mistaken as the same.
Higher Ah battery is better for some devices in certain occasions. When a battery’s Ah is higher, it will give more energy to the device. However, it should be noted that when the Ah is higher, the battery will end up to be bigger also.
So, you need to make sure that the battery’s size is suitable for your needs. If you need a small battery, then it’s best for you to use batteries with small Ah.
The same goes with charging time too. The bigger the Ah, the longer it will be to charge the battery. Again, if you need a short amount of time to charge the battery, then it’s best for you to use batteries with a normal or small amount of Ah.
So, if you want to use batteries with large Ah, it’s best when:
- Your device needs a large amount of power in a single run
- Your device has a sufficient space for the large battery
- You don’t need to be in a hurry because it will take a while for the battery to recharge.
Unless your condition suits the requirements above, then it’s best for you to use small Ah for your device(s).
There is no such thing as improving the Ah of the battery. However, you can double the amount of Ah you will get if you do certain tricks.
If you want to double your Ah, here are the things you must get first:
1. Battery with similar specifications.
If it’s possible, use batteries from the same brand. This is important because it can affect the delivery of the current. Batteries with similar specifications will have the same kind of components, so there will not be any resistance ratings within the battery.
2. The batteries must be in the same health. No more, no less.
This is extremely important also. Batteries with used-up Ah will end up pulling each other, causing something that is similar to point number 3.
3. The batteries must have the same Ah rating
The same Ah rating is important, as there can be consequences if the Ah of one is smaller than the other. If such a case happens, the battery with smaller Ah will end up discharging first and draw the current from the battery with larger Ah.
The main trick to get more Ah for the battery is by putting two batteries in a parallele. Putting two batteries in parallel position will give you Ah twice than it normally is. Of course, you cannot do that carelessly. There are some things and steps you need to do if you want to increase the Ah properly.
Now that you have all the materials, here are some tips you should mind when you put the batteries in parallel.
Here are the things you should do when you put your batteries on parallel:
1. Do not put them in parallel right away.
The biggest mistake people do is to put the batteries in parallel right away. However, that is one of the worst mistakes you must never make.
Before you put the battery in a parallel position, you need to ensure that there is a resistor between the two batteries. After putting the resistor, you will also need to ensure that the batteries equalize each other. Equalizing is important because one of the batteries will definitely have a higher output voltage. This can result in the weaker battery being considered as a short circuit for the stronger battery.
2. Check the manual of the batteries carefully.
You need to make sure that everything that has been told from the points above is exactly how it should be on the battery. It means that your batteries must fulfill the requirements. Or else, you will have a hard time doubling the Ah. You might even cause some serious damage too.
3. Power Management System
Yes, you do need a power management system for a successful increase of Ah. This is because of the complicated way of the process. That is why a power management system is needed to keep everything in order.
If you have everything in order, then go ahead and improve the Ah of your battery! Good luck!
