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 (11 V, 25 V 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).
