2.1 Battery ranges
In order to enable Alpha to offer an appropriate
solution in accordance with the customer's
requirements and to have a choice for any battery
application existing on the market, Alpha Ni-Cd
batteries are designed in four different performance
ranges.
This Alpha cell type has been especially designed
for low rates of discharge over long periods, viz the
current is relatively low in comparison with the total
stored energy. The discharges can generally be
infrequent and the recommended discharge time for
the KL ...P range is 1 hour to 100 hours.
The Alpha M type has been especially designed
for "mixed loads" that include a mixture of high
and low rates of discharge. It is used for frequent
and infrequent discharges and the recommended
discharge time is 30 min to 120min.
The Alpha H type was designed especially for high
current discharging over short discharge periods. The
recommended discharge time for this cell range is 1 s
to 30 min
This Alpha cell type is a further developed M type,
which provides caused by a special perforation
higher discharge currents for special application up
to 1 hour. It is especially used for UPS and similar
applications and the recommended discharge time is
10 min to 60 min.

2.0 Battery Range and Applications
2.2 Applications and choice of cell type
Alpha Ni-Cd batteries cover a wide range of
applications and are used in almost every sector,
no matter if it is a private, industrial, commercial,
governmental or military one. The table on page 8 on
which some examples can be found represents only
a small overview in te extended fi eld of applications.
Therefore, it is to be understood as a precept and
general information.
