Star Portable Printer Battery Guide
This guide provides information and considerations on how to keep the battery
powering your Star Micronics Portable Printer operating at its best.
Printers Covered: SM-S
What kind of batteries do Star Portable Printers support?
Star Portable Printers support Lithium-Ion (also known as “Li-Ion”) batteries.
Is there an advantage to using a Li-Ion Battery compared to oth er types?
Li-Ion is a widely accepted type of rechargeable portable battery and is the most common
type used in modern electronics like cell phones, laptops, mobile printers and more.
The Li-Ion battery was preceded by Nickel Cadmium (NiCd) and Nickel Metal Hydride
(NiMH) types. These older batteries were prone to “the memory effect” causing them to
lose energy capacity over time if they were charged when only partially discharged. Li-Ion
batteries are not subject to this iss u e, are lightwei ght and can be produced in many shapes.
Do Star Portable Printers ship with a battery and charger?
Yes, every Star Port able Printer ships with one battery pack and a charger cable.
200, SM-T300, SM-S300, SM-S400
Note: The above battery pack is designed for the SM-T

How do I maintain my battery for be st performance?
Get the best performance and longest life out of your battery by following these guidelines:
Use the battery pack to power only the Star Portable Printer model it was designed for
Use only the approved Star Micronics charger to charge the battery pack
Fully charge the battery prior to using the printer
Remove the battery pack if the printer is or will be ou t of use for several days

Do not use, charge, or leave the battery pack near a fire, in direct sunlight,
or in any other hot location
Do not drop the battery pack or subject it to strong shocks
Do not immerse the battery in water or allow it to be spl ashed by liquid
Can I mix and match batteries amon g different Star models?
Star Portable Printer batteries can not be traded betwe en printer series due to differences
in battery shape and size. For example, the SM-S
200 cannot swap a battery with the SM-
T
therefore, one SM-S
300. However, batteries can be freely traded among Star Printers within the same series;
200 can swap a battery with another SM-S200.
Can I use any charger to charge my battery?
Star Micronics strongly urges using only a Star charger to charge batteries. The Star
charger was designed for and tested extensively with the provided ba ttery models and are
guaranteed to operate correctly when used under the recommended con ditions. Star
chargers supply the correct amount of voltage and amplitude necessary , but this cannot be
guaranteed if a third party device is used.
How long will my battery stay charged?
Charge life depends on many factors, including:
• If the work shift began with a fully charged battery
• Length of print out
• Amount of information printed
• Frequency of printing
• If Auto Power Down Mode i s con f igured
• Battery Age
• …And More
The typical life of one new fully-charged Star battery is a minimum of
9 hours and can
extend up to
