BMP53 and BMP51 Lithium Ion Battery Pack

How many labels can be printed on a full battery charge?
Using 8 fully charged AA batteries, you should be able to print
around 1,200 1" x 2" labels with 20% coverage. With the optional
rechargeable Li-Ion battery pack, you can print over 3,000 labels.

Can I use the printer while the optional Li-Ion battery pack is charging?
Yes; power will be sent to both the charging system and to the
printer at the same time.

Can I charge my battery outside of the printer?
Yes. The BMP51 / BMP53 AC power supply also charges the Li-Ion battery
pack inside or outside the printer.

Can I charge my printer via USB cable connected to my PC?
Not at this time.

How long does it take to charge my optional Li-Ion battery pack?
A fully drained battery pack will take around 2-3 hours to charge
completely; longer if the BMP51 or BMP53 printer is being used while charging.
