There are a lot of different battery types for mobile phones. Therefore it can be very difficult to know which one to buy. They are all different in how much they weight, how long they last, how they're shaped and how big they are. Not only that, but to add to the confusion even more the mobile phone batteries also have very complicated names and descriptions.

This article will aim to help you picking out the specific battery type that is the most suitable for your Sharp mobile phone.

We will start with the weight and size of the battery.
Many batteries weight differently, have different shapes and have different sizes, why? Well, the mobile phones that they are compatible with may be smaller or bigger and therefore the spot where you pop in the battery is also therefore a different size. The batteries may also be made of different materials which will also contribute to the size and weight difference.
So it's important that if you are looking to buy a new battery for your mobile phone that you ask the staff of the store or website if the battery does fit with your mobile phone. You can also bring your mobile phone with you if you are going to a store so that you can ask to try the different batteries. The little plastic boxes that they store the batteries in are usually sealed and you will not be allowed to open one before purchase but they often have one behind the counter that you can try out.
The size is the important thing to keep in mind here, the weight will most likely not be an issue since most mobile phone batteries weight very, very little.

The second factor that you need to keep in mind when looking for a mobile phone battery to buy is the longevity of the battery. This one is very much up to you, if you are able to charge your battery every day it may not be that important for you if the battery can last 40 hours before charging again. However, if you are not able to charge it that often, longevity may be more important to you.

Here you can find out more about the specific battery types and their names.

First we have Lithium Polymer (Li-Poly) batteries; these batteries are very light and will usually last 40% longer than NiMH batteries, more on NiMH cell phone batteries later.
Li-Poly batteries can however be hard to find, Internet is often your best bet.

Then we have Lithium Ion (Li-Ion) batteries; this type is very popular for cell phones and you will find them all over the place. Li-Ion cell phone batteries also weight very little and they also last for a very long time.
However, these batteries can cost quite a lot of money.

Third up are Nickel Cadmium (NiCd) batteries; this type is an old type. The quality of these are not that great because you have to wait until the battery is dead before recharging and they are also not very good for the environment. Therefore NiCd cell phone batteries are very cheap.

Lastly we have the Nickel Metal Hybrid (NiMH) batteries; unlike the NiCd batteries, NiMH batteries are environmentally friendly. The technology used is quite new.

When picking out a battery for your Sharp cell phone, if you are unsure which one to pick, ask someone that does know more about cell phone batteries.

Some good places where you can buy batteries are; your local store, an online store or a website such as Craigslist, Gumtree or eBay.
