Charging the Collar
To prevent corrosion, thoroughly dry the contacts on the collar and the surrounding area before connecting the charging clip.
You should fully charge the battery before you use the device for the first time or whenever the battery is low (Checking the Battery Level). It is normal for the battery to discharge in approximately 7 to 10 weeks when the device is not in use. Charging a fully depleted battery takes about 2 hours.
NOTE:
The device will not charge when outside the temperature range of 32° to 104°F (0° to 40°C).
