• Do not recharge any battery pack other than Battery Pack BP-511A, BP-514, BP-511, or BP-512.
• Battery Pack BP-511A is dedicated to Canon products only. Using it with an incompatible battery charger or product may result in malfunction or accidents for which Canon cannot be held liable.
• If the battery is left in the camera for a prolonged period, a small amount of power current is released, resulting in excess discharge and shorter battery life. Take out the battery from the camera and attach the protective cover before storing. Storing the battery after it is fully charged can lower the battery's performance.
  

note:

The time required to recharge the battery depends on the ambient temperature and the battery's recharge level. If effective time is sharply reduced even after normal recharging, the battery pack may have reached its service life. Replace it with a new battery.
