347Technical Notes
• 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.
