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.

And charging is li ion stock the best thing about Li-ion batteries there's absolutely no memory effect. And they charge quickly. Battery manufacturers always like to say they've reduced the memory effect, or even 'virtually eliminated' it. But it's never true, you might get away with charging the battery from half full every now and again, but if you keep topping them up then the capacity always goes down. With Li-ion they don't need to reduce the memory effect, there isn't one.

One thing that can cause that whole problem to be avoided is to keep spare laptop batteries. This allows one to be charged while the other is being used.

It just takes a moment to change out one battery for the other and the laptop is ready to go for another few hours.

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.

Don't empty the battery completely. Modern safety circuits take care of this, but if you take it to 3% capacity, then leave it like that for three months, it's most probably going to be damaged and lose some of its maximum capacity. If you have to store it for a while, charge it to 60%, and leave it like that in a dry and cold place.
