• Keep the battery in a cool, dark place; do not store it for

longer than 6 months without recharging.

• If you are using one battery: Completely discharge and

then recharge the battery once every 90 days.

• If you are using two batteries: Swap the left and right

batteries every month.

• Fully charge a replacement battery before using it; Apple

ships batteries in a partially charged state.
