The Complete Guide to Buying Batteries for Your Mobile Phone

Mobile phones are, perhaps, one of the most noteworthy inventions the modern world has got to experience. These communication devices are more than just a basic calling and texting device. With smartphones making their presence felt like no other, the game of mobile phones has gone to the next level completely. Modern mobile phones are more of an entertainment device or a portable computer for their users, with calling and texting features taking a backseat quite often. Mobile phones are no longer a luxury; even an average 21st-century citizen cannot go through a day sans fiddling with his phone. As modern mobile phones have become a mini-computer of sorts, their power requirements are also increasing. Despite regular care and cautious usage, mobile phone batteries tend to get diminished on the power front over a period of time, thereby creating the need for purchasing a new and better mobile battery. A mobile phone battery is not a complicated piece of modern hardware; however, zero knowledge about the same would not help, either.

About Mobile Phone Batteries

A rechargeable battery is what makes a mobile phone function the way it does. These rectangular combinations of chemistry and physics are what are needed to keep a phone alive and functional. A mobile phone battery uses nickel cadmium, nickel metal hydride, or a lithium ion for getting powered up and holding onto the charge. The older mobile phone batteries were made from chemical substances, such as nickel cadmium and nickel metal hydride. Modern mobile phones use lithium ion batteries as their primary source of power. With improved technology and better materials, some modern mobile phone manufacturers are able to design smartphones that can accommodate high-performance batteries, which can last up to a couple of days on a single charge. That being said, the power-efficiency of the battery also depends on the mobile operating system it serves. Some operating systems are more efficient at consuming battery power, while others could be a bit too power-hungry.

Buying Mobile Phone Batteries

The battery of a mobile phone not only adds to the standby time of the device, but it also helps with the phone’s functioning and other systems. An incompatible and low-quality battery would not only fail to serve the user’s power needs, but it could also end up sabotaging the phone. Buyers should, therefore, be a bit more knowledgeable about these batteries and their mechanisms. Being aware of battery types, the compatibility aspects, etc. would help an individual make a better and sensible buying decision.

Kinds of Batteries

There are four kinds of mobile phone batteries; the difference is in their designing and manufacturing process.



OEM Batteries

OEM (Original Equipment Manufacturer) batteries are made by mobile phone manufacturers and are identical to the ones that come with the mobile phones. They provide the same talk time, standby time, and durability as the original batteries.

Non-OEM Batteries

Also known as generic batteries, non-OEM batteries are manufactured by third party manufacturers. Though quite identical in their looks and design, the performance of these batteries is comparatively low when compared to original batteries.

Refurbished Batteries

Refurbished batteries are used and defective batteries that are sent back to the original manufacturers for repair work. Once repaired and tested by the manufacturers, these batteries are sold in the market at subsidised rates.

Grade A Batteries

These are nearly as good as new or stock batteries and are the ones that are sent in as replacements by the network operators. Grade A batteries are quite competitively priced and serve as great alternatives to OEM batteries.

Mobile Phone Types

The wide range of mobile phone hardware justifies the availability of different battery types in the market. Buyers should, therefore, be aware of the batteries that are compatible with their devices.



Li-Poly Batteries

Li-Poly (Lithium Poly) batteries belong to the category of the modern or smartphone generation of mobile phone batteries. They are the slimmest and lightest batteries available in the market and can stack up immense power only on a single charge.

Li-Ion Batteries

Li-Ion (Lithium Ion) batteries are the most commonly used batteries. They are thin and light in weight and can address any mobile phone’s power requirements for a day.

NiMH Batteries

NiMH (Nickel Metal Hydride) batteries belong to the past generation of mobile phone batteries and are compatible with mobile phones that existed prior to the smartphone era.

NiCD Batteries

NiCD (Nickel Cadmium) batteries are the oldest of the lot, and the phones that used these batteries are no longer in demand or have gone obsolete. These batteries are quite heavy and had to be drained out completely before setting it up for a charge.

Extended Batteries

These batteries are slightly thicker and heavier than the above stated battery types. Though very good at providing additional power to a device, their thickness often protrudes out from the phone’s back, thereby giving a bulgy look to the device.


Most mobile phones have compatibility issues when it comes to the batteries available in the market. Almost all mobile phones have different power requirements. Therefore, certain factors have to be taken into consideration when testing a phone’s compatibility with its battery.

mAh Count

mAh (Milliamp-hour) is the total capacity of the battery. The higher the mAh, the longer would be the battery’s power capacity. Users looking for longer battery life for their phones tend to go for a higher mAh count.


Most mobile phone batteries support electrical charge that is close to 3.7 volts. However, there are also some batteries that can withstand higher voltage treatment. The voltage requirements and capacity of the battery must be looked into when buying batteries for the phone.


Warranty is the most essential aspect of any device or accessory. It is the indication of the levels of confidence that the manufacturer has in its products. In other words, a warranty helps a consumer get the product repaired or replaced if the product gets dysfunctional or does not perform as per factory specifications. Warranty promises and the duration differ with manufacturers. While there are some brands good at keeping their warranty promises, some others might just not pay heed to the customer’s grievances. Usually, OEM batteries come with manufacturer warranty. That said, some third party manufacturers may also provide a replacement guarantee on their products. The used or refurbished batteries are not backed by such warranties. Therefore, buyers who are more concerned about reliability and after-sales service must go for batteries with warranty.

Authorised Dealer

Authorised dealers are sellers who deal with genuine and original products. There are many other dealers who sell fake batteries or the mere replicas of the original. Though there are some who sell fake accessories blatantly, some of the others try to hoodwink the buyers and sell them counterfeit batteries at the cost of the original. It is quite difficult to differentiate between original and fake batteries. People who are not good at distinguishing between real and fake products should feel safe with authorised dealers.

Finding Mobile Phone Batteries on eBay

Launch the eBay homepage and click on the Mobile Phones & Communication sub-category displayed upon highlighting the Electronics & Technology, which stays at the left side of the website. Locating and clicking the Mobile Accessories from the left panel will display the entire range of accessories available with eBay. Buyers can access the required product listing page by clicking the Batteries options displayed on the left panel. The results displayed can be filtered down on the basis of brand, condition, price, and many other aspects. Buyers can complete their shopping by either making an outright purchase or by putting in their bid for the product. eBay does not sell products on its own; several companies and individuals sell products via the eBay platform. In such a scenario, trying to know a bit about the seller would always come in handy. The seller’s ratings and customer reviews would be a good indication of the seller’s reputation and credibility.


With mobile phones getting smarter and more efficient by time, the power requirements of these gadgets are nothing but bound to go up. Buying a new phone would be the most obvious option for people who are fed up with their phone’s battery performance. For others who are not too keen on spending that extra money on a new phone just for a defective battery, a replacement battery would be a much wiser option. Though mobile phone batteries are not as complicated as some of the related terminologies might indicate, some basic knowledge about these accessories would only make things even better. With the variety of options available in the market, an individual would only have to be a bit clearer about his or her usage requirements. In addition, the compatibility aspects should not be overlooked either.
