DSC-P71, DSC-P71M - Sony Digital Camera Service Manual (repair manual). Page 11

Use the following batteries in this camera.

R6 (size AA) Nickel-Metal Hydride 
batteries (2) 

NH-AA-DI  (2)  (supplied)

NH-AA-2DI  twin-pack  (recommended, not 
supplied)

Manganese batteries, lithium batteries, ni-
cad batteries, alkaline batteries (cannot be 
used with the DSC-P71)

Use of AA alkaline batteries may result in 
shorter than desired operating time. (only in the 
DSC-P31) 
When alkaline batteries are used, take note of 
the following information.

Turn POWER SAVE “ON”, shut the LCD 
screen off, and use the Finder to shoot your 
images. This will lengthen battery life 
(page 16).

There is a big difference in the performance 
of batteries of different types and of batteries 
made by different manufacturers. This is 
especially true in low temperatures, where 
some batteries are noticeably weaker.
You may not be able to shoot in temperatures 
below +5°C (41°F).

The battery remaining indicator may not 
display the correct information.

Be sure to charge the Nickel-Metal Hydride 
batteries supplied with your camera before 
using them.

Be sure to charge the batteries in an 
environment where the ambient temperature is 
10°C to 30°C (50°F to 86°F). If the batteries are 
charged in an environment where the 
temperature is outside that range, the batteries 
may not charge efficiently.

Connect the battery charger to an easily 
accessible wall outlet (mains) close by. If 
something goes wrong while you are using the 
charger, immediately shut off the power by 
pulling the plug out of the wall outlet.

Charging starts, and the charge lamp lights. 
When the charge lamp goes out, charging is 
finished.

When charging is finished, disconnect the 
power cord (mains lead) from the wall outlet 
(mains), and remove the Nickel-Metal Hydride 
batteries from the charger.

When transporting the Nickel-Metal Hydride 
batteries, be sure to use the battery case 
(supplied). If the 

+/− metal terminals are 

shorted, there is a possibility of danger from 
excessive heat or fire.

If the poles of the Nickel-Metal Hydride 
batteries are dirty, the batteries may not 
charge properly. Occasionally clean the poles 
of the batteries and the terminals of the 
charger by wiping them with a dry cloth.

At the time of purchase, or when the Nickel-
Metal Hydride batteries haven’t been used for 
a long time, they may not fully charge. This is 
typical of this type of battery, and is not a 
malfunction. If this happens, repeatedly using 
up the battery fully, and then recharging it, 
should correct the problem.

Even when Nickel-Metal Hydride batteries 
are not being used they loose their charge 
naturally over time. It is recommended that 
you recharge the batteries just before using 
them.

If you recharge Nickel-Metal Hydride 
batteries before fully using up the existing 
charge, the so-called memory effect* can 
occur, and the low battery warning will be 
triggered sooner than expected. Charging the 
battery after fully depleting the existing 
charge should correct the problem.

The “memory effect” – the situation in 
which a battery temporarily accepts a less 
than full charge.

• To use up the batteries completely, put 

the camera in “SLIDE SHOW” mode 
and leave it that way until the batteries 
are used up (page 67).

Do not charge any other batteries except Sony 
Nickel-Metal Hydride batteries in the charger 
supplied with your camera. If you try to 
charge any other type of battery (e.g., 
manganese batteries, alkaline dry cells, or 
one-time lithium batteries) than the batteries 
specified, those batteries may leak, overheat, 
or explode, causing the danger of burns or 
other injuries.

Be sure to charge both Nickel-Metal Hydride 
batteries at the same time.

When the batteries are charged, use them only 
in an environment where the temperature 
range is 0°C to 40°C (32°F to 104°F). 
Otherwise, there is a danger of leaks, 
explosions, excessive heat, fire, or electric 
shock.

Do not charge fully charged Nickel Metal 
Hydride batteries again. Otherwise, there is a 
danger of leaks, explosions, excessive heat, 
fire, or electric shock.

Do not peel off the external seals or damage 
the batteries. Never use batteries from which 
the seals have been partially or completely 
removed, or batteries that have been split in 
any way.

This represents the time required to charge 
fully depleted Nickel-Metal Hydride 
batteries using the supplied BC-CS1 
charger in an environment where the 
ambient temperature is 25°C (77°F).

Charging is complete in approximately 13 
hours. The charge lamp may remain lit longer 
than 13 hours, but this is not a malfunction.

If you use the ACC-CSNQ STAMINA “Super 
Quick charge” kit (not supplied), the batteries 
will charge faster.
