295Technical 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.
• Recycle rechargeable batteries in accord with local regulations, being
sure to first insulate the terminals with tape.
