Notes about the Battery Pack
u General Battery Characteristics
• The battery is a consumable and its performance over time will gradually decrease.
• While not in use, 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 environ-
ment.
u Charging the Battery Pack
• The battery pack can be charged at ambient temperatures between 0 and 40°C.
• The time required to charge the battery pack varies depending on the voltage and the am-
bient temperature.
Normally, it takes 4 to 5 hours to charge the battery pack.
• It will take longer to charge the battery pack if you print while charging the battery pack.
• Do not remove the battery pack while it is being charged.
• There is no need to completely discharge or use up a rechargeable lithium ion battery be-
fore recharging 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.
u Battery Pack Life
• The battery can be charged approximately 500 times in the normal temperature range
without losing performance. If an extreme decline in the running time of the battery is no-
ticed, the battery is reaching the end of its usable life. It is recommended to replace the old
battery with a new one.
u Notes about Using the Battery Pack
• Only use a designated battery pack.
• Only use the designated battery charging method.
You cannot use a battery charger other than the designated battery charger.
• 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.
• 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).
