CHAPTER 7: Maintaining Your Notebook Batteries with fuel gauges (convertible notebooks) should be recalibrated once every 30 charges. If ignored, the fuel gauge becomes increasingly less accurate and in some cases will cut off the device prematurely. For more information about recalibrating the batteries, see "Recalibrating the batteries" on page 71. Using the right charger is important. By now you probably know that each kind of battery has its own technology, its own rate of charge, and so on. Charging lithium batteries correctly is one way to extend their life and to avoid damage. Clean the gold or silver connector on the batteries (the part of the battery that makes contact with the convertible notebook) with alcohol or electronic contact cleaner. Cleaning helps maintain good contact, which improves the transfer of power from the batteries to the convertible notebook. Storing batteries Do not charge up a battery, then store it away. A stored battery should be used every three to four weeks. Let the battery fully discharge, then recharge to 40% if you plan to store it again. If you store a battery for longer than three to four weeks, the battery could fully discharge because the battery circuitry itself consumes power. If you have a spare lithium-ion battery, use one exclusively and keep the other cool by placing it in the refrigerator. Make sure that it is wrapped protectively and that nothing will be dropped on it. Do not freeze the battery. Do not use old batteries. Avoid purchasing spare lithium-ion batteries and storing them for later use. Do not buy old stock, even if it is sold at clearance prices. While it makes sense to have 2 or 3 extra batteries, so that you always have a fresh one charged up and ready to go, if you buy batteries and store them for years, they may not work when you decide to use them. Consider removing the battery from your convertible notebook when running on fixed power. However, remember that when you have removed the battery from your convertible notebook while using it with an electrical outlet, the automatic battery charger no longer keeps the battery charged. Caution When the battery is in the convertible notebook and the convertible notebook is running on AC power, the battery constantly charges, even though it has a full charge. This reduces the life of the battery. If the battery is fully charged and you want to run on AC power, remove the battery. 90

CHAPTER

: Maintaining Your Notebook

Batteries with fuel gauges (convertible notebooks) should be

recalibrated once every 30 charges. If ignored, the fuel gauge

becomes increasingly less accurate and in some cases will cut

off the device prematurely. For more information about

recalibrating the batteries, see

“Recalibrating the batteries” on

page 71

Using the right charger is important. By now you probably

know that each kind of battery has its own technology, its own

rate of charge, and so on. Charging lithium batteries correctly

is one way to extend their life and to avoid damage.

Clean the gold or silver connector on the batteries (the part

of the battery that makes contact with the convertible

notebook) with alcohol or electronic contact cleaner. Cleaning

helps maintain good contact, which improves the transfer of

power from the batteries to the convertible notebook.

Storing batteries

Do not charge up a battery, then store it away. A stored

battery should be used every three to four weeks. Let the

battery fully discharge, then recharge to 40% if you plan to

store it again. If you store a battery for longer than three to

four weeks, the battery could fully discharge because the

battery circuitry itself consumes power.

If you have a spare lithium-ion battery, use one exclusively

and keep the other cool by placing it in the refrigerator. Make

sure that it is wrapped protectively and that nothing will be

dropped on it. Do not freeze the battery.

Do not use old batteries. Avoid purchasing spare lithium-ion

batteries and storing them for later use. Do not buy old stock,

even if it is sold at clearance prices. While it makes sense to

have 2 or 3 extra batteries, so that you always have a fresh

one charged up and ready to go, if you buy batteries and store

them for years, they may not work when you decide to use

them.

Consider removing the battery from your convertible

notebook when running on fixed power. However, remember

that when you have removed the battery from your

convertible notebook while using it with an electrical outlet,

the automatic battery charger no longer keeps the battery

charged.

Caution

When the battery is in the convertible notebook and the convertible

notebook is running on AC power, the battery constantly charges, even though

it has a full charge. This reduces the life of the battery. If the battery is fully

charged and you want to run on AC power, remove the battery.
