You might ask "What is the 3V motherboard battery"? On the majority of PCs the motherboard holds a +3 Volt Lithium Battery which is used for two functions. Firstly it keeps the computer time updated. Secondly, on older PC's it keeps the BIOS settings (Low level start-up instructions) in memory.

If you have your PC case off you will see something on the motherboard that looks like a small thick silver coin. That is the battery. There are other types of battery used on newer machines (Ni-Cad, NVRAM) but these much less frequently found and so I won't discuss them further.

This can be a problem for where the battery is not used that often but is can be important when it is needed for emergencies such as power outages. As the battery does not store well over extended amounts of time, it is possible that when they are needed they will not be usable. But for things that are used and recharged on a regular basis such as for portable electrical equipment, they are very good. But there is not always a slowing amount of capacity when they are getting old and it is possible for them to just not lithium ion stocks work without any reason being obvious.

2) Battery freshness: often overlooked. Always make sure you have the freshest battery possible. A battery can lose it's ability to hold a charge as time goes on. You want batteries that move off of shelves quickly to be sure they aren't old.

Another thing to remember is not to store those batteries in the charger as well. This will draw energy away too, and cause your battery to die off sooner than you expect. Keep it away from high heat or extreme coldness. Heat tends to cause damage to your Lithium battery stocks while exposing it to low temperatures over a period of time will draw its charging capacity.

Things certainly have changed over the years. There are enough options available today to make a person's head spin. There are even more variations and innovations in the works as I write this. While the scope of this guide will not be able to cover every type of power drill in existence, we are going to try to cover most of the bases. My goal in writing this article is to help those who might be having difficulty deciding which type of drill they need, so let's get started.

With any battery, every time you charge it, it loses a bit of its performance and power. Over time, that battery will die, and after you give it a proper funeral, you'll have to change it. The same is true with your iPOD. Eventually, you will have to replace the iPOD battery. You can either change the iPOD battery itself or purchase a new iPOD Nano . But, because your iPOD battery is a lithium-ion beast, you won't need to worry about that for a while!
