Panasonic LUMIX DMC-FX33 Operating Instructions Manual page 12

∫ Charging conditions
• Charge the battery in a temperature
between 10 oC to 35 oC. (The battery
temperature should also be the same.)
• The performance of the battery may
temporarily deteriorate and the operating
time may become shorter in low temperature
conditions (e.g. skiing/snowboarding).
• The battery may swell and its operating time
may become shorter as the number of times
it is charged increases. For long term battery
use, we recommend you do not frequently
charge the battery before it is exhausted.
