Laptops Batteries
What are the types of Laptop batteries?
There are three types which described 
below:
-
Nickel Cadmium (NiCd): This type of batteries were the first to be used for the laptops and notepads , they where low in cost and provide high outputs but they are not being used any more these days because of their heavy weight and inefficiency comparing with the newer types as described below.
-
Nickel Metal Hydride (NiMH): This is the most reliable and has higher output than the NICd ones and even safer to use; this type of batteries still can be found but used with old types of Laptops.
-
Lithium-ion (Li-iON): This is the best battery type you need to have and use in your laptop; it has a lot of advantages unlike the NiMH and NiCd types as it has a light weight, more powerful, more reliable and more environmentally friendly comparing with the other types. Also it has enhanced features like it doesn’t have the Memory Effect feature and a slow loss of charge when not in use.
How can I identify which type my own laptop battery is?
It’s so easy just remove the battery from the laptop and read the information on its back as shown in the below pictures.
What is the Battery default life time?
Normally the Laptop batteries life time will be approximately 500 recharges, in another words if you take care of the below points on how to gain a long lasting battery life time you will gain approximately 2-3 years of good battery performance which represented by 1.5 hour to 3.5 hours every time useage depending on which applications you are using.
What should I do to gain a long lasting battery life time?
-
When having a new laptop and will be used for the first time, charging your new battery overnight is sufficient to give your new battery a full charge.
-
Your new battery should be charged and discharged 3-4 times during the first month of usage.
-
Reducing the LCD brightness and the usage of CD/DVD drive will defiantly increase the battery time for holding the charge.
-
If you use to plug the AC adapter to your Laptop while using it all the time, remove the battery to extend its life and store it when not in use in a nonmetal and non conducting container in a cold dry place.
-
You can use the power saver option in Windows power plan option for a longer life performance, and to perform that open the Power Options from the Control Panel and select the Power Saver Option then click ok.
What precautions should I know about Batteries?
It’s obvious to say but don’t burn, disassemble, short circuit or mutilate, crush, puncture or incinerate batteries, my additional advice is not to leave your laptops in a hot environments as the below video describes what would happen if the laptop battery got extremely hot. (It’s worth watching)

Definitions:
Memory effect: Also known as lazy battery effect or battery memory, is an effect observed in (NiCd) rechargeable batteries that causes them to hold less charge. It describes the very specific situation in which certain (NiCd) batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to remember the smaller capacity.
