Chapter 3: Getting To Know NEO

Storing Batteries

Lithium-ion batteries do not require conditioning cycles and the NEO battery system does not require user interaction to maintain peak performance.

To determine the remaining charge in the battery, you can tap on the Power icon in the Control Panel to display a dialog box that provides detailed information about the battery status of the main battery installed in your unit. You can also tap on the Power icon in the taskbar to display the battery status.

To maximize the run time of your batteries, consider the following:

•The hand-held is ‘event’ driven—that is, when the unit is not in use, it 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 unnecessary events, and allow the unit to sleep as much as possible.

•NEO uses a smart battery with built-in intelligence.

Tapping on the Power icon in the Control Panel displays a dialog box that provides detailed information about the battery status of the main battery installed in your unit.

•When the hand-held is switched off, it goes into a low-power, suspend state but contin- ues to draw a small amount of power from the battery. This should not be an issue unless the unit is left in suspend state for more than a week—for long-term storage, the battery should be removed from the unit.

•Reduce display brightness.

•Turn off the keyboard backlight if not required.

3.7.1Storing 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 (32 °F and 68 °F).

•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.
