5.1
Type L
The SBL is designed for applications
where the battery is required to
provide a reliable source of energy
over relatively long discharge
periods. Normally, the current is
relatively low in comparison with
the total stored energy, and the
discharges are generally infrequent.
Typical uses are power backup and
bulk energy storage.
5.2
Type M
The SBM is designed for applications
where the batteries are usually
required to sustain electrical loads
for between 30 minutes to 3 hours
or for “mixed” loads which involve a
mixture of high and low discharge
rates. The applications can have
frequent or infrequent discharges.
The range is typically used in power
backup applications.
5.3
Type H
The SBH is designed for applications
where there is a demand for a
relatively high current over short
periods, usually less than 30 minutes
in duration. The applications can have
frequent or infrequent discharges.
The range is typically used in starting
and power backup applications.
5.4
Choice of type
In performance terms the ranges
cover the full time spectrum from
rapid high current discharges of
a second to very long low current
discharges of many hours. Table 2
shows in general terms the split
between the ranges for the different
discharge types. The choice is related
to the discharge time and the end of
discharge voltage. There are, of
course, many applications where
there are multiple discharges, and
so the optimum range type should be
calculated. This is explained in the
chapter “Battery Sizing”.
