What would you do without them? Seriously, if every single battery of every single type were suddenly zapped out of every single thing that it operated, what would any of us do?
This classy device will set you back as much as $179, which is a bit steep considering that you can buy a Bluetooth headset now for as little as $30, but you get what you pay for.
Why is this important? If you have a relatively new PC the only problem you will get are error messages relating to the clock on start up. No big deal. If your PC is older then a low battery could be a nightmare. I had a PC which once cobalt mine every few months refused to boot. Rather than take the PC in for repair or start replacing parts myself the first thing I did was look at the BIOS settings. It was soon obvious that the BIOS settings were corrupt (wrong bus speed). I put a volt meter on the battery and sure enough it was reading 2.2 volts.
In case you some how do not use the battery for 3 months or more, the above described procedure should be followed before you restart using the battery as normal.
The Lithium battery stocks-ion battery is light years ahead of the earlier batteries and considerably better than the Nickel-cadmium (Ni-Cd) or the nickel-metal hydride (Ni-MH) batteries which are still being used. These batteries are less expensive but the Li-ion batteries are far superior in three ways.
Lithium mines Ontario-Ion batteries are revolutionary in fact, not just simply better than Ni-Cd. They don't have memory effect, which means you can easily use them a little and then partially recharge them just to discharge them to a certain percentage of their capacity other than zero. They like partial charges and discharges better than full ones, but memory effect is not something you should be aware of.
Laptop computer uses: If you keep the battery in your laptop for everyday use, and power it from the wall socket, unplug the power every few days and let it run off the battery, as a battery at 40% capacity lasts longer than one at 100% capacity. if you don't travel with it, you should remove the laptop battery when on fixed power.
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.
