B. Tips and Safety Guidelines for Lithium-Ion Batteries B Battery Tips • Charge batteries in a room-temperature environment, which is generally between 68° F and 79° F (20° C and 26° C). Charging may be temporarily disabled if the battery temperature exceeds 113° F (60° C). • If a battery exhibits significantly shorter runtime or discharge capacity compared to new, it may have reached the end of its reasonable lifetime; consider replacing it. • A battery that does not charge or exhibits excessive charging time may have reached the end of its life and may need to be replaced. • All batteries degrade and lose charge capacity over time as a result of use or storage, and eventually need to be replaced. • Batteries are best stored in a cool, dark, dry place. Avoid storage in direct sunlight and in vehicles parked outdoors. • Batteries may get warm while charging and discharging; this is normal behavior for all batteries. • Use the wall charger and the USB cable that came with this device. • Use the latest firmware; check for software updates on a regular basis. • Device performance and runtime are affected by workload or usage. Higher workloads or usage can lead to higher battery temperatures and faster battery power consumption. • Streaming large amounts of data affects the power consumption and reduces the operating time of the battery. General Battery Safety • Stop using a battery if its case appears damaged, swollen, or compromised. Examples include, but are not limited to, leaking, odors, dents, corrosion, rust, cracks, swelling, melting, and scratches. • Do not expose batteries to fire or other heat- generating environments. • Do not place the battery or the device in areas that may get hot. Examples include, but are not limited to, on or near a space heater, cooking surface, cooking appliance, iron, radiator, or fireplace. 81
