Chapter 3: Get To Know The Ikôn
Storing Batteries
Ikôn Rugged PDA (Windows Mobile 6.1) User Manual 49
Lithium-Ion batteries do not require conditioning cycles and the Ikôn battery system (in-
cluding chargers) requires no user interaction to maintain peak performance.
To maximize the run time of your batteries, consider the following:
The display backlight is a large drain on the battery. Try to keep its brightness as low
as possible.
The Ikôn is ‘event’ driven—that is, when it is not in use, the Ikôn reverts to sleep mode
(even when it appears to be running), saving battery power. Events include a key press,
touchscreen taps and scan triggers. Power consumption is reduced if you avoid unneces-
sary events, and allow the Ikôn to sleep as much as possible.
The battery is a ‘smart battery’ with built-in intelligence.
Tapping on the Power icon under Start>Settings>System tab displays a dialog box that pro-
vides detailed information about the battery status of the battery installed in your Ikôn.
When the Ikôn is switched off, it goes into a low-power, suspend state but continues to
draw a small amount of power from the battery. This should not be an issue unless the
Ikôn is left in suspend state for more than a week—for long-term storage, the battery
should be removed.
3.7.1 Storing Batteries
Long term battery storage is not recommended. If storage is necessary:
Always try to use a ‘first-in first-out’ approach to minimize storage time.
Lithium-Ion batteries age much faster at elevated temperatures. Store batteries at tem-
peratures between 0° C and 20° C.
Always charge batteries to at least 40 to 60% before storing them. Batteries can be
damaged by an over-discharge phenomenon that occurs when an empty battery is stored
for a long period of time such that the cell voltage drops below a lower limit.
To minimize storage degradation, recharge stored batteries to 40 to 60% every 4 or 6
months to prevent over-discharge damage.
A ‘never used’ Lithium-Ion battery that has been stored for 3 years may have limited or
no useful life remaining once put into service. Think of batteries as perishable goods.
