LIFEPAK 1000 Non-Rechargable battery

The Lifepak 1000 battery pack has a shelf life of five years and does not require recharging. The approximate level of charge in the battery is indicated by the fuel gauge on the battery, on the readiness display when the defibrillator is off, or on the screen when the defibrillator is in use. When optimally maintained, a new nonrechargeable battery pak can provide approximately 17 hours of “ON” time or 440 discharges at 200 joules.
