Using AA Batteries
EN-EL4a or EN-EL4 rechargeable Li-ion batteries (available separately) or 
EN-EL3e rechargeable Li-ion batteries are recommended for best 
performance. Fewer pictures can be taken with AA batteries (pg. 417). 
The capacity of AA batteries drops sharply at temperatures below 20 °C 
(68 °F) and varies with make and storage conditions; in some cases, 
batteries may cease to function before their expiry date. Some AA 
batteries can not be used; due to their performance characteristics and 
limited capacity, alkaline and nickel-manganese batteries should only be 
used if no alternative is available and then only at warmer temperatures. 
The camera shows the level of AA batteries as follows: 
Battery level for EN-EL3e, EN-EL4a, or EN-EL4 rechargeable Li-ion batteries 
is displayed normally.
