1 Safety instructions

➪ Do not connect to any fixture or ballast whilst in contact with

water, if your hands are wet or damp or if connectors are

wet or damp!

➪ Do not place the Belt-Pack

®

battery in water!

➪ Allow for unobstructed air flow for convection cooling, espe-

cially when charging the battery!

➪ Handle with care! Do not throw! Do not drop!

➪ Only for professional use! Keep batteries out of reach of

children and personnel that has not been instructed in the

use of high power Belt-Pack

®

batteries!

➪ Do not pack a warm battery into a transport case!

➪ Do not charge a battery whilst in a transport case!

➪ Do not over-charge! Do not short-circuit!

A Sachtler Belt-Pack

®

high power battery can produce cur-

rents up to 90 A which can have dangerous effects if out of

control.

➪ Do not expose the battery to fire! Exhausted batteries can

be recycled by Sachtler.

2 Properties

2.1 General

The Sachtler Belt-Pack® family consists of batteries with

different voltages and capacities:

Type nom. voltage nom. capacity

Bat 12V/4.5Ah B1245 13.2V 4.5 Ah (60 Wh)

Bat 12V/7.0Ah B1270 13.2V 7 Ah (90 Wh)

Bat 30V/4.5Ah B3045 30V 4.5 Ah (140 Wh)

Bat 30V/7.0Ah B3070 30V 7 Ah (210

Wh)All sachtler Belt-Packs® have the following features

in common:

Belt-Pack

- 2 -

➪ selected heavy-duty NiCd cells developed for high cur-

rent applications

➪ cell arrangements are embedded in special design for

increased mechanical ruggedness and safety

➪ housing is ergonomically shaped

➪ the interface is compatible with all Sachtler fixtures,

Sachtler electronic ballasts, and Sachtler chargers

➪ Shoulder strap and belt

2.2 Operation

The Belt-Pack® batteries are equipped with a belt and a

shoulder strap. Adjust the shoulder strap to carry the bat-

tery conveniently at your hip. If you carry the battery at the

right side of your body, the shoulder strap should rest on

the left shoulder, and vice versa.

Use the belt to “lock” the battery to your body.

2.3 Open circuit voltages

The output voltages of NiCd batteries can be higher than

the nominal voltages listed under 2.1, if a battery was fully

charged:

➪ B1245 and B1270 max. 16.5V

➪ B3045 and B3070 max. 35V

Once a fixture or ballast is connected and operated, these

open circuit voltages will drop to the respective nominal

voltages after a few moments. The connected fixture or

ballast must be able to safely operate with these higher

voltages. All Sachtler products are designed to meet these

requirements.

Manual

2.4 End of discharge voltage

A Belt-Pack® battery is considered completely discharged,

once the voltage has dropped down to 11V with 13.2V

types B1245 and B1270 and down to 25V with 30V types

B3045 and B3070.

To prevent deep discharging, the batteries must not be

discharged beyond this voltage! All Sachtler Batronics will

automatically switch off, once the limit of discharge voltage

has been reached. Sachtler Reporter fixtures R100H and

R250H must be switched off once the red LED on the fixtu-

re flashes! Sachtler fixtures R20H and R50H have neither

an automatic switch-off nor an indicator. With these fixtures

a significant reduction of light output and colour temperatu-

re indicates that the end of discharge voltage has been

reached and the luminaire must be switched off, since

otherwise the battery will be deep discharged. If deep

discharge occurs several times, the life time of the battery

will be reduced considerably.

2.5 Thermal properties

Professional TV lighting fixtures draw high currents from

their connected battery packs.These high currents increa-

se the internal temperature of the battery pack noticeably.

Immediate fast charging may cause damage to the cells.

So allow for cooling down before charging if battery tempe-

rature is increased! Also do not draw high currents from a

battery as long as battery temperature is raised!

Please note: At very low temperatures a battery will

have low capacity.

NiCd batteries must not be charged when they are too hot

(over 50°C/118°F) or too cold (below minus 10°C/14°F). At

room temperature it can take several hours before a bat-

tery which was too hot or too cold can be charged or

discharged again. If not operated or charged within this

temperature range, irreversible damage to the battery may

occur.

2.6 Memory effect

2.6.1 Description

Sachtler NiCd batteries are free of a memory effect

when used through full charge-/discharge cycles in

connection with Sachtler fixtures. Under certain ope-

rating conditions, like permanent charging and/or

over-charging combined with very little discharging,

a reversible loss of capacity may be noticed.This

may also happen if the battery is only discharged at

higher temperatures in the range of 30°C to 50°C

(86°F to 122°F).The full capacity will, however, be

restored after a full discharge down to the end of

discharge voltage (11V, 25V resp.).

2.6.2 Reasons for capacity loss

The memory effect should not be confused with a

capacity loss caused by over-charging or over-hea-

ting since this capacity loss is irreversible. External

short-circuiting of a battery can also cause an irre-

versible loss of capacity which is displayed by volta-

ge loss and capacity reduction during discharging.

2.7 New Belt-Pack® batteries

For safety reasons Sachtler ships Belt-Pack® batteries in

discharged mode.The fully rated capacity will be available

after approximately five full charge-/discharge cycles.

2.8 Storing Belt-Pack® batteries

When storing Sachtler Belt-Pack® batteries please make

sure that the storage temperature is kept between minus

10 °C and 40 °C (14 °F and 104 °F).

2.9 Shipping Belt-Pack® batteries

For safety reasons ship batteries in discharged mode! Also

make sure that temperature is kept between minus 10°C

and 40°C (14°F and 104°F).

2.10 Self discharge and deep discharge

NiCd batteries discharge themselves at a rate of approx.

1% of the rated capacity per day – even if not used.Thus a

fully charged NiCd battery looses 50% of its capacity in

approx. 50 days. After approx. 100 days its voltage has

decreased to the end of discharge voltage: The battery is

virtually empty. Further storage without usage leads to the

deep discharging of the battery.

This status can be eliminated by running the battery

through several charge/discharge cycles.The full rated

capacity will be restored (see 2.6 Memory effect). During

the use it may happen that a battery is not automatically

disconnected at the end of discharge voltage (see 2.4 End

of discharge voltage) and accidentally becomes deep

discharged. If the battery is charged soon afterwards, the

full nominal capacity will be available immediately.

2.11 Power limits for Sachtler Belt-Pack® batteries

Based on the internal wiring and the connectors the power

drawn from Sachtler Belt-Pack® Batteries has to be within

the following limits:

Type max. power max. current

B1245, B1270 130W continuous 10A continuous

200W short term 15A short term

B3045, B3070 360W continuous 12A continuous

600W short term 20A short term

Drawing higher current than listed above may result in a

defective battery.

3 Charging

Use Sachtler chargers, only! Please read and adhere to the

manual of the Sachtler charger used.

3.1 Speedcharger (Code No. C1232)

A microprocessor-controlled high-tech charger for all

Sachtler Belt-Pack® batteries.The Speedcharger monitors

all important parameters of the battery being charged and

charges the same amount of energy into the battery which

was discharged before.

3.2 Charger 12 (Code Nr. C1200) and Charger 12AS (C1202)

Compact overnight charger for Sachtler Belt-Pack® batte-

ries B1245 and B1270, applies a low current charge which

does not require any monitoring and time control.

4 Recycling

The battery cells of Sachtler Belt-Packs

®

can be 100% recycled.

Please be aware of your responsibility for a tidy environment

and send exhausted batteries back to Sachtler. We will recycle

them free of charge.

5 Troubleshooting

There are no serviceable parts inside. Please use the following

troubleshooting tips in case of malfunction.

Problem

The battery does not deliver any power:

The battery does not accept any charge:

Capacity is not sufficient:

Remedy

Is the socket / plug damaged?

Has the battery been properly charged?

Is it exhausted?

Is the socket damaged?

If a Sachtler Speedcharger is used: Is the

temperature sensor defective? (The Spee-

dcharger’s LEDs would clearly signal this

condition.)

Charger is not charging, because battery

is too hot (>50°C (118°F)) or too cold

(<-10°C (14°F)).

Is it exhausted?

Was it over-charged?

Was it discharged at high temperatures?

Is the battery too cold?
