BATTERY MANAGEMENT
The Ankle is powered by a state-of-the-art Lithium-Ion Battery. The Batteries have
been tested to last 1 million steps and still maintain 80% of their original capacity.
Users typically get 3 to 6 hours of battery life a day depending on their usage.
To ensure the Battery provides the longest life possible, try the following:
• When possible, charge the Battery before it becomes fully depleted. It may
extend battery life.
• Always charge the Battery after use. Storing an empty Battery can make it
unusable in as little as 30 days.
• Do not store the Battery in the Ankle when not in use. This can deplete its life.
• Before charging the Battery, allow it to warm or cool to room temperature.
• After inserting the Battery in the Charger, watch the status light on the Charger
for 10 seconds to confirm the Battery is actually charging.
• Store and charge the Batteries in a climate-controlled, dry location out of direct
sunlight. Avoid leaving the Batteries in a car where temperature extremes can
permanently damage the Batteries.
EXTENDING SHELF LIFE
The most common problem people experience with their Batteries is the result of
incorrectly storing them, because a Battery continues to slowly discharge during
storage. A fully charged Battery can be stored as long as 3 years. Storing a discharged
battery may cause it to become permanently disabled in as little as one month.
A Battery left in the Ankle will also drain relatively quickly (3% per day) even if the
Ankle is powered OFF. To extend Battery life, fully charge and store it separately
from the Ankle or the Charger.
UNDERSTANDING SLEEP MODE
If a Battery suddenly loses power, it may have automatically shut down as a precaution
for safety reasons or to protect the Battery. You will know if this happens as the
Ankle will lose all power the same as when the ON/OFF switch has been turned OFF.
The Ankle will continue to function, but it will not offer powered propulsion and it
will feel heavy.
