General Battery Characteristics
The battery is a consumable and its performance over time gradually decreases.
While not in use of printer, the battery will slowly discharge itself.
Prepare a battery pack that has been charged relatively recently (1 to 2 days earlier).
To ensure that the battery lasts for a long time, we recommend that you turn off the printer whenever
possible.
When used at low temperatures, battery performance will temporarily decline. Be sure to have a
fully-charged spare battery standing by if the printer will operate in a cold environment.
Charging the Battery Pack
The battery pack can be charged at ambient temperatures between 0°C and 45°C (0 - 10°C：Max.
0.5 A (Recommendation)). When the printer is used in a low temperature environment(less than 10
degrees), the battery’s performance will be diminished, and the amount of time that you can use the
printer for may be reduced.
The time required to charge the battery pack varies depending on the residual amount of battery,
electrical current and the ambient temperature. Normally, it takes around 5 hours to charge the
battery pack.
It will take longer to charge the battery from the PC than by the USB charger supports 1.0A.
It will take longer to charge the battery pack if it is printing while charging or power on.
Do not remove the battery pack while it is being charged.
Fully charge the battery prior to using the printer.
There is no need to completely discharge or use up a rechargeable Lithium-ion battery before
recharge it.
It is normal for the battery pack to be hot after it has finished charging or been used.
Do not recharge a battery pack that has just been fully charged.
Battery Pack Life
The battery can be charged approximately 300 times in the normal temperature range without losing
performance. If an extreme decline in the running time of the battery is noticed, the battery is
reaching the end of its usable life. It is recommended to replace the old battery with a new one.
Notes about Using the Battery Pack
Only use a designated battery pack.
Only use the designated battery charging method.
You cannot use a USB cable other than the designated USB cable.
Do not throw the battery into a fire, place it near a flame or heating device, or leave it in a hot
environment (under direct sunlight, in a car, etc.).
Do not use a battery pack that has been dropped or subjected to a shock in some other way.
Notes about the Battery Pack

8
Do not disassemble or modify the battery pack.
Do not short the terminals of the battery pack or get it wet.
Do not place the battery pack in a bag with a small metal object (such as a key).
If any battery fluid gets on your skin or clothing, immediately wash the affected area with fresh water.
Otherwise, skin damage may result.
Notes about Storing the Battery Pack
The characteristics of the battery pack may degrade if you store it in a full-charged state for a long
period of time. If you do not intend to use the battery pack for a while, store it in approx. 50%-
charged state.
If you do not intend to use the battery pack for a long time, be sure to remove it from the printer.
Keep the battery out of the reach of children. In addition, be careful that children do not remove the
battery.
Store the battery pack in a cool place.
* We recommend that you store the battery pack in a dry area with an ambient temperature of
15 to 25 ºC.
* Avoid storing the battery in locations with high or extremely low temperatures.
