• Charge the battery before use. When taking photographs on 
important occasions, ready a spare battery and keep it fully charged. 
Depending on your location, it may be difficult to purchase 
replacement batteries on short notice. Note that on cold days, the 
capacity of batteries tends to decrease. Be sure the battery is fully 
charged before taking photographs outside in cold weather. Keep a 
spare battery in a warm place and exchange the two as necessary. 
Once warmed, a cold battery may recover some of its charge.
• Used batteries are a valuable resource; recycle in accord with local 
regulations.
