Technical Notes
Charge Batteries Before Use
Charge the battery before use. The supplied battery is not fully charged at
shipment.
Ready Spare Batteries
Before taking photographs, ready a spare battery and keep it fully
charged. Depending on your location, it may be difficult to purchase
replacement batteries on short notice.
Have Fully-Charged Spare Batteries Ready on Cold Days
Partially-charged batteries may not function on cold days. In cold
weather, charge one battery before use and keep another in a warm
place, ready to be exchanged as necessary. Once warmed, a cold battery
may recover some of its charge.
Battery Level
•
Turning the camera on or off repeatedly when the battery is fully
discharged will shorten battery life. Batteries that have been fully
discharged must be charged before use.
•
A marked drop in the time a fully charged battery retains its charge
when used at room temperature indicates that it requires replacement.
Purchase a new rechargeable battery.
Do Not Attempt to Charge Fully-Charged Batteries
Continuing to charge the battery after it is fully charged can impair
battery performance.
Recycling Used Batteries
Recycle rechargeable batteries in accord with local regulations, being
sure to first insulate the terminals with tape.
