5.4 BATTERY OPERATION OVERVIEW
Technical Service Manual 5 - 15 430-00587-008 (Rev. 2/05)
CAUTION: As soon as the LOW BATTERY alarm occurs, connect the infusion system
to AC (mains) power.
Recharging occurs any time the infusion system is connected to AC (mains) power. It is
recommended that the infusion system be connected to AC (mains) power whenever
practicable to maximize available battery charge during transport or ambulation. The
power switch does not have to be on for the battery to recharge. Recharging while the
infusion system is operating is rate dependent.

Note: The infusion system should be operated on battery power for six continuous
hours at least once every six months for optimum battery performance and life.

BATTERY CHARGER CURRENT TEST (OPTIONAL)
To perform the battery charger current test, refer to Figure 5-7, Battery Charger Current
Test Configuration , then proceed as follows:

Note: Make certain the battery is in good condition and charged. If necessary, use a
second battery for this test.
1. Disconnect the infusion system from AC (mains) power. Remove the battery access
cover and disconnect the battery.
2. Connect the battery charger test circuit as illustrated in Figure 5-7 . Make certain
switch S1 is in the off position.
3. Connect the infusion system to AC (mains) power and allow 20 seconds for the
current to stabilize. Read the current on the current meter.
4. Compare the measured current to the minimum and maximum values in Table 5-2,
Battery Charger Current Test Parameters .

Note: If the reading is too low, the battery may be fully charged. Close switch
S1; repeat Step 3 and verify per Table 5-2 .
5. Disconnect the infusion system from AC (mains) power. Remove the battery charger
test circuit. Reconnect the battery to the infusion system. Replace the battery access
cover and secure
