What Is mAh (milliampere-hour)? mAh In Batteries – Explained!

So, here we are going to talk about what exactly mAh – milliampere hour – is and also what mAh is in relation to batteries.

What Is mAh?

What does mAh mean? This abbreviation stands for milliampere-hour, and this represents the 1000th of an ampere-hour. This is the unit that measures electric power over a period of time. This unit of measurement is widely used by manufacturers to express the capacity of a battery in order to store energy. This is specifically true in smaller batteries.

The official abbreviation for milliampere-hour is actually mA-h or mAh. But almost all producers of any devices which have batteries use the more unofficial abbreviation that we know to be mAh. This is an abbreviation that is much more commonly used without a space between the value and the abbreviation.

Additionally, it is important to note that ampere-hour or milliampere-hour are not capitalized when they are written fully. However, when they are abbreviated the letter A from ampere must always be capitalized.

How Does mAh Relate To Rechargeable Batteries?

When it comes to thinking about rechargeable batteries, then the measure mAh is a pretty big indicator of the energy charge which a battery can hold. Not only this but the measurement also outlines the time that it will power the device for until the battery then needs to be recharged. 

This all depends on the type of battery. In each case, the mAh consumption will be pretty different. However, there is one factor that applies in the majority of cases and that is all to do with the mAh rating in batteries. The higher that this rating is, the more electrical energy that the battery can actually store.

This ultimately means that a rechargeable battery with a much higher mAh will be capable of powering a device for an extended period of time.

This works well in theory because actually, the real power transfer from the battery to the device is pretty inefficient. This means that only part of the charge will end up being transferred – and this is why real battery capacity differs from what is printed on the product.

Let’s Talk About mAh In Smartphone Batteries

Let’s Talk About mAh In Smartphone Batteries

Right now, the average capacity for smartphone batteries is marginally above 3300mAh, and it is true that the most popular sizes range from 2000 mAh right up to 4000 mAh. 

You might think that these sizes seem pretty small – but manufacturers have actually increased this kind of capacity. This is especially true when you compare the capacity to a few years ago. It is important to remember that 4000 mAh batteries will not be the best or the usual mAh for smartphone batteries. This is because a better-equipped smartphone battery will be available in the market as time goes on.

Does More mAh Mean That You Will Get A Longer Phone Usage Time?

Nowadays people actually have a pretty great interest in really understanding their cell phone’s battery capacity. This is because this will help you to plan your day and work out just how frequently you will need to recharge your phone.

If you are someone who frequently has long commutes then this is especially true for you. You will be keen to know how long your battery will last as you will want it to be able to serve you well for a prolonged period of time. 

This is why a lot of people will consider purchasing portable chargers just so that they have a backup option if their phone dies. When it comes to buying a phone, people will be a lot more aware of the fact that a battery that has a much higher mAh will run for much longer. 

Yeah, this is why people are a lot more particular about the battery capacity that their cell phone has before they buy a new one – or before they replace their cell phone’s battery. 

It is also important to mention that the battery life of a device will be influenced by the way that the device is used. So, if you are someone who uses your cell phone pretty regularly then you will find that you recharge your cell phone practically all the time.

Alternatively, if you are someone who uses their cell phone much more conservatively – so you just use your phone for texting, or for making shorter calls then you will not have to recharge your phone very regularly.

How Can You Extend Your Cell Phone’s Battery Life?

Lots of people will purchase power banks as a way of extending their cell phone battery life and usage in general. With the majority of cell phones these days, you cannot take out the battery and replace it with another battery that has a much larger capacity.

This would not be something that is especially practical. If you are looking for a way to extend your cell phone’s battery life then you can consider investing in a power bank because it can extend your battery life up to two times.

Alternatively, knowing the right amount of time that a battery will last for is not always super obvious. It is true that technical specifications do provide an estimate of a device’s battery life but these values can really differ in reality.

This is all in relation to a variety of factors such as the brand of the device along with the model of the device. The length of time at which you use the device will also have an impact on how long your device’s battery life will last.

We have used ‘device’ to categorize a range of electrical devices, this is not something that just applies strictly to cell phones. This is something that can actually apply to any device. 

Will mAh Influence The Lifespan Of Your Battery?

First of all, let’s just start off with a rough guideline for the life expectancy of lithium-ion batteries. These kinds of batteries are usually what is found in cell phones and these batteries will usually last for approximately three years. This is the kind of time frame that we would give to a cell phone battery that is being used constantly. 

When it comes to rechargeable batteries, they have a pretty limited number of charges before they begin to wear out. In fact, some estimates state that this limit is between 300 and 800 times on average. So, the number of charge-discharge is also referred to as cycle life. This is the very reason that usage habits have become a factor that has an effect on the average lifespan of a battery.

Capacity can become a bit more confusing when it comes to working out how this relates to the actual lifespan of the battery. You might be wondering whether a larger capacity means that your battery will have a longer life or a shorter life. Well, the very answer to this is that the mAh value of a rechargeable battery does not have any kind of influence on its lifespan. What does have an influence on its lifespan is the way that it is used?

Why Is It Important For You To Know The mAh Of Batteries?

Well, being familiar with the mAh of the batteries of your devices will really help you to work out the period of time that the battery will last for. This will help you when it comes to making these big purchases, you will be much more confident in the device that you are investing in. You will not only have a device that meets your needs, but you will have a battery that will meet your day to day needs too. 

In Conclusion

Overall, the mAh in batteries is much more of a measure of capacity. This means that the higher the mAh value is, the longer that the battery life will be. It is important to remember that this is not the only indicator of the battery capacity or the battery life. In fact, the battery life of your device will in general depend on you.

After all, as the main user of the device, you will have your own usage patterns and this will affect the current output of the device. The lifespan of your battery will ultimately depend on the number of charge-discharges that are experienced.
