It really is very frustrating to have a weak battery that cannot hold much power to last a day with average activity. Reasons for a weak battery are the misuse of the battery and the lack of proper maintenance. The capacity of a mobile phone battery is measured by its standby time and talk time. It is measured in milli-amph hours (mAh). Rechargeable batteries have three main types, Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (LiIon). Lithium Ion (LiIon) batteries are what you find in most mobile phones and in order to preserve the battery you might want to follow these steps.

The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.

There are two things that kill a notebook battery; heat and operating outside its voltage specifications, overcharge or undercharge in plain English.

Now yes, it depends on how you're using it. But the Apple creators say it will play movies solidly for hours for example before the Lithium mines Ontario iPad battery says feed me".

Some cordless impact drills are now using lithium-ion batteries which take a lot less time to get a full charge. For instance, I personally use a Makita 18V lithium-ion impact drill and it takes fifteen minutes to charge as opposed to my standard 18V Dewalt drill. The Makita is also equipped with a built-in LED light for illuminating areas with little to no light. The LED light feature in particular is one of my favorites.

Compare the prices of regular cellphone batteries to cheap cellphone batteries and you will realize that you definitely got a good deal. Just have these batteries tested before buying them. See if these are compatible to your cellphone.
