Charging time in the printer is approximately 3.0 hours
Take the battery out of printer if storing the printer for long periods of time
The battery storage temperature is 40°F to 104°F (4°C to 40°C). Do not

printing sessions. Certain operations (for example, printing receipts with a lot
of bar codes and graphics) drain the battery more quickly than others
