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.
The battery chemistry has 3 types: NiCad, NiMH, and Lithium-ion. NiCad, or NiCd, battery is used in older cordless drill tools. They are the least expensive, so almost all inexpensive cordless tools use this type of battery. There is one problem with this battery. It's toxic to the environment. So when it's time to dispose the dead NiCd battery it's a problem.
It seems the Dodge Ram 1500 pickup trucks were prone to damage due to their prototype batteries. There are no reported fires or injuries to operators as a result of the damage. Chrysler is testing a lithium stock powered battery since the third quarter of 2011. The project was expected to run through 2014, but no plans have been made to extend the testing.
Much of the response to the threat of Giardia is overkill. A favorite scholarly article on Giardia was written by Robert L. Rockwell, PhD. It's titled, Giardia Lamblia and Giardiasis, With Particular Attention to the Sierra Nevada. Bob Rockwell is an active mountaineer who made his first trip into the Sierra Nevada in 1952 to climb Mt. Whitney, and he repeats this climb several times annually. He has a bachelor's degree in Physics from UC-Berkeley, and a PhD in Aeronautical and Astronautical Engineering (Biomechanics) from Stanford.
The weakest aspect of any smart phone would be battery life. You need to know the extent of your Lithium battery stocks Ion or suffer the consequences at the end of the sale. Most manufacturers offer some guidance on this department but only to the point they are most comfortable to share. What they wouldn't share to you is that you should never recharge your phone. You pick up the phone; saw that it is just around 30%. That is OK, leave it as it is. You juice it up fast, the device will not recharge as efficiently once you do it again. You need to drain the battery first from the stock power and then do the recharge.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.
So how long does it last? Anything from 3 to 9 years if you search this question on Google. Everyone has a different opinion. In my experience about 6 years is the average. It's basically a large watch battery and is constantly supplying a trickle of power to the motherboard. Just like many of my watches the battery can last 2 years or up to 6 years (Fossil watches don't seem to last long for me for some reason). How long was the PC in the warehouse before it was delivered? And, how long was the motherboard in the warehouse before it was installed in the PC?
Third, it is quite important to fully charge the battery every time, also to run the battery to be empty every time. The reason is the battery will lose charge day after day if the battery in your notebook is a nickel metal hydride. Therefore, your battery will dies a certain days later and you need to order a new one. Your work will be affected and money will come out of your pocket. Shortly, you can keep your battery in a good condition for a long time if you do as what have mentioned above.
