Storing Batteries - Gateway E-155C Technical Reference Manual

Do not expose the battery to high heat or freezing temperatures.
Hot batteries discharge very quickly, and cold ones cannot
create as much power. Short battery life is more likely to be
caused by heat than by charge/discharge patterns. Keep your
lithium-ion battery cool. Avoid a hot car, for example.
Charge often, but do not try to fully discharge the battery
frequently. This only adds strain. Several partial discharges
(regular use), with frequent recharges, are better for lithium-ion
than one total discharge. Recharging a partially charged
lithium-ion battery does not cause any harm because it has no
memory.
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 battery, see
page
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 battery (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 battery 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.
