LIFEPAK 20/20e Defibrillator/Monitor
Battery Maintenance
Charging the Backup Battery
The LIFEPAK 20 defibrillator/monitor has a built-in, high-current charger that
recharges a completely discharged backup battery in approximately two hours
when ac power is connected to the device. The charger does not recharge the
battery until one week has passed since the battery’s last full recharge or until
the battery has been disconnected and then reconnected.
The LIFEPAK 20e defibrillator/monitor has a built-in, constant, current-constant
voltage charger that recharges a completely discharged backup battery in
approximately four hours when ac power is connected to the device. The
charger does not recharge the battery until the Li-ion battery's state-of-charge
drops below 85%.
Note:
The LIFEPAK 20e defibrillator/monitor will only initiate battery charging if
the battery pack is below 40° C. If extensive defibrillator shocks have
been applied to a device in a high ambient temperature, the battery will
not immediately start charging.
