Failure to use a Franklin Wireless approved battery and charger may increase the
risk that your device will overheat, catch fire, and/or explode resulting in property
damage, serious bodily injury, and/or death.
Battery life can vary based on the network, signal strength, temperature, features,
and accessories you use.
If you connect your device to your computer using the USB
cable,
the battery will charge.
It normally takes at least 3 hours to fully charge the battery with an A/C Power
adapter.
New batteries or batteries stored for a long time may take additional time to
charge.
When charging your battery, keep it near or below room temperature.
Never expose batteries to temperatures below 32°F (0°C) or above 113°F (45°C).
