extend the battery life, it’s best not to let the Lithium Ion battery discharge completely
before recharging. Keep the Controller plugged into the charger or charging cradle
when not in use, or charge it overnight, as this type of battery does not suffer from
memory effect and can be charged anytime.
Battery Replacement
After several years (depending upon usage), the battery on your Controller may not
hold a charge as long as it once did. Because of the Controller’s splash-resistant design,
the battery on the Controller must be factory-replaced. Return it to the Sonos Service
Center where it will be promptly replaced and returned to you. Go to
for instructions and battery replacement cost.
Caution: Use only the supplied power adapter to charge the Controller’s battery.
Using another adapter will damage your Controller and void your product
warranty.
Caution: Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type. Return to Sonos or an authorized Sonos service
center for replacement.
