Q: How to charge the backup batteries?


A: 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.


The CodeManagement Module has a built-in lithium-ion battery charger that recharges a completely discharged backup battery in 4 hours when AC power is connected to the device. The battery should be replaced every two years. Battery replacement must be performed by qualified service personnel.
