Batteries - Nikon Coolpix L340 Reference Manual

Notes About Smear
White or colored streaks may be visible when bright subjects are framed in the monitor.
This phenomenon, known as "smear," occurs when extremely bright light strikes the
image sensor; it is characteristic of image sensors and does not indicate a malfunction.
Smear may also take the form of partial discoloration in the monitor during shooting.
It does not appear in images saved with the camera except in the case of movies.
When shooting movies, we recommend that you avoid bright subjects such as the
sun, reflected sunlight, and electric lights.

Batteries

Precautions for Use
Note that the batteries may become hot after use.
Do not use batteries beyond their recommended expiration date.
Do not turn the camera on and off repeatedly if discharged batteries are inserted in
the camera.
Carrying Spare Batteries
We recommend carrying spare batteries depending on where you are shooting. It
may be difficult to purchase batteries in certain areas.
Charging Batteries
If using optional rechargeable batteries, charge the batteries before taking pictures.
Batteries are not fully charged at the time of purchase.
Be sure to read and follow the warnings noted in the operating instructions included
with the battery charger.
Charging Rechargeable Batteries
Do not mix batteries with different amounts of charge remaining, or batteries of a
different make or model.
When using EN-MH2 batteries with this camera, charge four batteries at a time using
Battery Charger MH-73. Use only Battery Charger MH-73 to charge EN-MH2 batteries.
When using Battery Charger MH-73, only charge EN-MH2 batteries.
EN-MH1 rechargeable Ni-MH batteries cannot be used.
Notes About Rechargeable Ni-MH Batteries
If you repeatedly charge rechargeable Ni-MH batteries while they still have some
charge remaining, the message Battery exhausted. may be displayed prematurely
when using the batteries. This is due to the "memory effect," in which the amount of
charge the batteries can hold decreases temporarily. Use the batteries until there is
no charge remaining and they will return to their normal behavior.
Rechargeable Ni-MH batteries discharge even when not being used. We
recommend charging the batteries just before using them.
Using the Batteries When Cold
On cold days, the capacity of batteries tends to decrease. If exhausted batteries are used at
a low temperature, the camera may not turn on. Keep spare batteries in a warm place and
exchange as necessary. Once warmed, cold batteries may recover some of their charge.
