You depend on your M3538A Lithium Ion Battery to provide the energy necessary to operate your HeartStart MRx monitor/defibrillator. To ensure that the battery is ready when you need it, you should understand how the battery functions and how to care for it properly. This application note describes the characteristics and care of lithium ion batteries.
The M3538A Lithium Ion Battery was designed to provide the following characteristics:
Built-in fuel gauge - The M3538A Lithium Ion Battery has intelligence that enables it to estimate the battery’s current state of charge. Convenient battery power indicators illuminate to show you the state of charge as a percentage of a fully charged battery.
Safe and reliable - Redundant safety features in M3538A batteries protect the batteries and their users.
Quick charging - Lithium ion batteries can quickly charge to their full capacity because they do not require an overnight trickle charge. The M3538A battery takes approximately 2 hours to reach 80% of its capacity and 3 hours to achieve a fully charged state from a fully discharged state.
Tolerant of Partial Charging - Because lithium ion batteries are tolerant of partial charging, there is no effect on battery life when patient care requires you to suspend charging and use the battery before it is fully charged.
Low maintenance - Lithium ion batteries do not need to be reconditioned like many other types of batteries. They only require charging and periodic calibration.
Low self-discharge rate - The M3538A Lithium Ion Battery can sit on the shelf away from the HeartStart MRx for extended periods of time and still be ready to power the monitor/defibrillator when you need it. Spare batteries maintain their charge well. This makes lithium ion batteries well suited for use in settings where the monitor/defibrillator cannot be connected to a power source for charging between uses.
