Using the battery
The R12 includes a high-capacity Lithium-ion battery that fits into the back of the unit.
Battery life varies by configuration, applications in use, utilized features, and operating
conditions. Maximum battery capacity decreases with time and use.
DANGER: To avoid personal injury, handle the battery with care. Don’t open, puncture,
short, or expose it to fire or water. Keep the battery in an environment with ambient
temperature of less than 104°F (40°C). For example, don’t leave the battery in a closed car in
hot weather for an extended time. For more information, see the Safety and Regulatory
Guide packaged with the tablet.
