Nicad Battery
The battery is capable of the following typical
performance when fully charged:
• Standby 10ua - about 12 week’s
retention of program, data and
configuration. After that the Lithium cell
takes over.
• Viewing 30ma - 20 hours of editing
(25% less via RS232)
• Burning 180ma - 3 hours
programming - the actual number of
PROMS varies widely from about 100
oldest-type to 1000 latest-type
• Emulating 100ma - 6 hours emulating
(depends on amount of access that the
target system makes and the load it
places on the data lines).
Real work is a combination of activities, of
course.
Early warning of battery discharge and
automatic shut-off operates if the battery falls
below 8.4 volts. Shutting-off is orderly - there
is no harm to any device being programmed
and no loss of data, provided S4 is recharged
within a few days.
When the charger is ON, 650ma a.c flows into
S4 and this will recharge the battery in about
an hour. A reasonable working capacity will be
restored in much less time.
Deep discharges and fast recharges make the
battery last longer than a trickle of charge
which maintains a fully charged battery all the
time.
