Nothing is worse than a cell phone battery letting you down when you need it the most. Many people do not know that these essential parts come in a variety of grades conveniently labelled A, B, and C-grade cells. Whether a consumer wants the longest lasting charge, or a company prefers more reliability for all their device users, choosing the best aftermarket cell phone battery options makes sense.

First, it is important to understand that most cellphone batteries use lithium ion cells to function. Other options like nickel cadmium, lithium polymer, and hybrid types exist on the market, too. The latest models tend to use new options in Li-Poly (lithium polymer) technology. These are all rechargeable and designed to give the user continuous service over many charges. However, original batteries often need replacing, and that is where companies like Deji Battery Comes in.

Explore the details about different grades of battery for smartphones in a variety of brands like iPhone, Samsung, and Huawei. Once you recognize the benefits of quality, you can make a better informed decision about purchasing for your business or organization.


A-grade mobile phone battery cell

Any time something is labelled ‘Grade A’ you know it is the best or highest quality version of that product or part. The same thing holds true for batteries for mobile devices. These cells are manufactured to the most exacting standards and use the highest quality materials. No corners are cut. No shortcuts taken. They represent the best on the market today for their product type.

In most cases, A-grade cell batteries come directly from the brand manufacturing facility. They go through a rigorous process of planning, material choice, design, and production. Careful quality assurance happens at multiple steps throughout, and a quality control team checks everything at the end.For example, the iphone designated battery cell suppliers: Sony, ATL, LG production are A-class battery cells.

The end user gets a battery that is safer, more durable, more efficient, and will hold a charge longer than other options. This gives them the best results when using their smartphone, tablet, or other mobile device for work, ordinary communication, or entertainment.


B-grade mobile phone battery cell

While every battery on the market today must pass certain safety regulations and compliance rules, they do not all end up with the same quality. Grade B lithium battery cells are one step down from the top. This does not mean they are horrible or will not hold a charge at all, of course. Instead, there is a higher chance of failure or defects. The quality control process is usually not as rigorous for these manufacturers.Also, lower grade mobile device batteries tend not to have a high capacity for holding a charge. This means that the battery will run out more quickly. The user will have to charge it more frequently and for longer periods of time.


C-Grade Phone Batteries

The same characteristics that make a B-grade lithium cell worse than a Grade-A one are found in C-grade batteries. Only this time, they are even worse or lower quality. They do not store as much energy. They need more frequent and longer periods of charging. They will include lower quality materials that simply do not function, protect, or look as good as higher-grade options.



C-grade cells are also commonly stored in warehouses for a lot longer than other ones. Instead of a manufacturer creating a specific number of batteries for a customer directly, these are mass produced as quickly and cheaply as possible. Then, they sit around waiting for a bulk buyer. In the meantime, the materials and lithium ion cells degrade slowly, which makes them even more inefficient and dangerous. The end user receives an already depleted battery that will not hold a charge well and may even experience leaks or overheating.


Why You Should Choose A-Grade Cell Phone Batteries

The primary reason buyers opt for B-grade or C-grade batteries instead of top-quality ones is the upfront cost. Of course, lower quality products of any kind cost less than excellent ones. When it comes to something as important and potentially hazardous as cell phone batteries, however, it is not the time to get cheap.

Instead of choosing what is the least expensive, look for better value over time. In this competition, Grade-A options win every time. Cell phones have to work today, tomorrow, and next year with the same speed and reliability. This means the battery has to provide the same power over all that time. They also need to stay safe throughout their lifetime.



Recharging frequently over time depletes the overall capacity. In other words, you cannot get the same full charge the first time you charge the battery and the 500th time. This is where the difference between the various quality grades becomes truly noticeable.

An A-grade battery will go from 100% capacity when new to around 85% capacity after 500 charges. A B-grade battery will start at the same 100%, of course, but it will dwindle to 50% or less after the same number of charges. C-grade may become nothing more than expensive garbage even earlier. Longevity matters a lot when it comes to devices that so many people rely on for their everyday lives and important business.

How do you know if you are getting a Grade-A cell phone or mobile device battery? The information comes straight from the manufacturer. Every batch or individual item should come with a full test report that reveals the specifics of its design and production. This includes details like voltage, capacity, resistance, product codes, compliance information, and quality assurance checking where applicable.
