Datalogic Joya User Manual page 21

The battery pack autonomy varies according to many factors, such
as the frequency of bar code scanning, RF usage, battery life,
storage, environmental conditions, etc.
Close to the limits of the working temperature, some battery
performance degradation may occur.
The JOYA TOUCH should be charged at an ambient temperature
between 0 - 35º C (32 to 95ºF) to achieve the maximum charging
rate.
Never charge the device battery in a closed space where excessive
heat can build up.
As a safety precaution, the battery may stop charging to avoid
overheating.
The JOYA TOUCH may get warm during charging; this is normal and
does not mean a malfunction.
Even if the storage temperature range is wider, it is recommended
to store the terminal and the batteries at environmental
temperature, in order to achieve the longest battery life.
CAUTION
User's Manual
Avoid storing batteries for long periods in a state of full
charge or very low charge.
We recommend charging the battery pack every two to
three months to keep its charge at a moderate level to
maximize battery life.
Annual replacement of rechargeable battery pack
avoids possible risks or abnormalities and ensures
maximum performance.
