If the performance decrease is greater than 20% in a Lithium-Ion battery, the battery is
at the end of its life cycle. Do not continue to use, and ensure the battery is disposed of
properly.
The length of time that a battery power lasts depends on the battery type and how the device is
used. Conserve the battery life through the following:
Avoid frequent full discharges because this places additional strain on the battery. Several
partial discharges with frequent recharges are better than a deep one. Recharging a
partially charged lithium-Ion battery does not cause harm because there is no memory.
Keep the lithium-Ion battery cool. Avoid a hot car. For prolonged storage, keep the battery
at a 40% charge level.
Do not leave the lithium-Ion battery discharged and unused for an extended period
because the battery will wear out and the longevity of the battery will be at least shorter
than half of the one with frequent recharges.
Battery charge notice
It is important to consider the environment temperature whenever the Lithium-Ion battery pack
is charged. Charging is most efficient at normal room temperature or in a slightly cooler
environment. It is essential that batteries are charged within the stated range of 10°C to 45°C.
Charging batteries outside of the specified range could damage the batteries and shorten their
charging life cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C, which will increase the
internal resistance to cause heat and make the batteries unstable and unsafe.
Please use a battery temperature detecting device for a charger to ensure a safe
charging temperature range. Further, to protect and avoid battery from inflating, the
battery is detected for thermal protection and will not be charged when the
temperature of battery is over 50 degrees.
Do not leave the PDA Scanner for a long time in the charging cradle and do not
charge the battery with a cable long, which will shorten the battery life and cause
battery expanding/ballooning. The unit should not be subject to very high
temperature, excessive moisture, and direct heat. Avoid the battery from being fully
charged and staying in a high temperature environment. Avoid PDA Scanner or
spare battery from staying in a hot vehicle. For prolonging the storage time, keep
the battery at a 40% charge level. Lithium ion batteries oxidize least when they are
stored at the state of 40% charge.
