Sony DSR-250 User Manual

The following power supplies can be used with the camcorder.
•BP-L40 (A)/L60A/L90A lithium-ion battery pack
•NP-1B Ni-Cd Battery Pack (The DC-L1Battery Adaptor is required.)
•BP-90A Ni-Cd Battery Pack (The DC-L90 Battery Adaptor is required.)
•AC power (The AC-550, AC-DN1/DN2A, or CMA-8A AC Adaptor is required.)
Alternatively, you can make combined use of internal and external batteries, by
mounting one of the above batteries as an internal battery and connecting, such as a BP-
90A contained in a DC-210 Battery Adaptor to the DC IN 12V connector of the
camcorder as an external source.

With a battery pack, the camcorder will operate continuously for the time shown below.
BP-L40 (A): Approx. 190 minutes
BP-L60A: Approx. 420 minutes
BP-L90A: Approx. 700 minutes
The numbers above indicate the time using only the viewfinder.

Before use, charge the battery pack with the BC-L50/L100 Battery Charger.

Notes on using the battery pack
•A warm battery pack may not be fully recharged.
•Even when fully charged, battery packs gradually lose their charge naturally. Use the

battery packs as soon as possible after recharging.

•To prolong the life of battery packs, store them in a cool place (about 20 °C (68 °F)),

and charge in a place with an ambient temperature between 10 °C and 30 °C (50 °F to
86 °F).

•Before long-term storage, discharge the battery fully. This extends the battery life.
•It is recommended that the BP-L40 (A) be used at 30 W or less.
•When using the BP-L40 (A), the specified capacity may not be obtained if it is

connected to the camcorder with accessories which is operated at 30 W or higher,
especially when the ambient temperature is low.

•At low temperatures, the usable time of battery packs decreases. When the ambient

temperature is 0 °C (32 °F), usable time decreases by about 10%. (However, the usable
time is affected by the power consumption of the camcorder in addition to the usage
status of the battery packs.) The usable time of battery packs increases if they are
warmed to the room temperature (about 20 °C (68 °F)) before use at low temperatures.

•If you use the BP-L40 (A) at temperatures of 0 °C (32 °F) or below, when power

consumption of the camcorder and accessories is 40 W or higher (due to using a video
light, for example), power may break after a short time (a few minutes). To increase
the usable time, store the BP-L40 (A) in a warm place, and power on the camcorder
before the BP-L40 (A) cools down.

•Compared to the BP-L40 (A), the BP-L60A/L90A offer better performance at low

temperatures. The BP-L60A/L90A are recommended for use at low temperatures.

•Carrying a spare battery pack is recommended.

The BP-L40 (A)/L60A/L90A is free from memory effect. There is no need to
discharge it fully before recharging.
