Battery Safety Instructions (ES-300W/ES-300WR)

The battery is not fully charged at the time of purchase. Charge the battery fully before using the scanner on battery power.
Always charge the battery within a temperature range of 46°F to 95°F (8°C to 35°C). The battery cannot charge or may deteriorate if you charge it in an environment outside of this range.
If the battery is not fully charged within the specified time, stop charging. Otherwise, the battery could become hot, emit smoke, rupture, or catch fire.
If you are not using the scanner, charge the battery using the AC adapter on a regular basis (at least once every six months) to avoid letting the battery run out.
Turn off the scanner when not in use or set the scanner to turn off automatically to save battery power.
Do not place the product in a microwave oven or a high-pressure container. Otherwise, the battery could become hot, emit smoke, rupture, or catch fire.
If battery acid gets into your eyes or on your skin, immediately rinse the affected area thoroughly with water and seek medical treatment.
If battery acid leaks from a battery, or the product emits a bad odor, move the product away from flammable objects immediately. If the product is not moved, electrolytes leaking from the battery become hot, emit smoke, rupture, or catch fire.
Do not subject the scanner to physical impacts or drop the scanner. Otherwise, the battery could leak or the protection circuit in the battery could be damaged. As a result, the battery could become hot, emit smoke, rupture, or catch fire.
Do not use or place the product in temperatures exceeding 140°F (60°C), such as near a fire or a heater. Otherwise, the plastic separator could melt and the individual cells could short-circuit. As a result, the battery could become hot, emit smoke, rupture, or catch fire.
Do not use the product if it is leaking or damaged in any way. Otherwise, the battery could become hot, emit smoke, rupture, or catch fire.
Do not leave the product in a vehicle. Otherwise, the battery could overheat.
If the scanner's battery light flashes orange quickly during charging in the normal temperature range (46°F to 95°F [8°C to 35°C]) or the battery runs out too fast even on a full charge, the battery may be malfunctioning or at the end of its service life. Contact Epson support to replace the battery.
