Align the contacts, slide the battery in position on an angle, and insert the battery, top first, into a battery charging well.
Gently press down on the battery to ensure proper contact.
The Spare Battery Charging LED on the cup indicates the status of the spare battery charging. The battery charges from fully depleted to 80% in approximately 2 hours at 10°C to 45°C (50°F to 113°F), and from fully depleted to 80% in approximately 3.5 hours at 5°C to 10°C (41°F to 50°F) and 45°C to 50°C (113°F to 122°F).
In many cases the 80% charge provides plenty of charge for daily use.
To achieve optimal fast charging results use only Zebra charging accessories and batteries. Charge batteries at room temperature with the device in sleep mode.
