M3538A Lithium Ion Battery
The HeartStart MRx uses the M3538A Lithium Ion Battery. The battery has a fuel gauge with 5 LED indicators, each representing a charge of at least 20% of capacity. Press the fuel gauge button to illuminate the fuel gauge.
Type: Rechargeable, Lithium Ion; See battery label for capacity information.
Dimensions: 165 mm (H) x 95 mm (W) x 42 mm (D); (6.5 in. x 3.8 in. x 1.6 in)
Weight: Less than 1.8 lb. (0.82 kg)
Charge Time with instrument off: Approximately 3 hours to 100%. Approximately 2 hours to 80%, indicated by indicator. Charging the battery at temperatures above 45ºC may degrade battery life.
Capacity (one battery): At least 5 hours of monitoring with ECG, SpO2, CO2, temperature and two invasive pressures monitored continuously, NBP measured every 15 minutes, and 20 200J discharges (with a new fully charged battery, operating at room temperature, 25o C)
At least 3.5 hours of monitoring with ECG, SpO2, CO2, temperature and two invasive pressures monitored continuously, NBP measured every 15 minutes, and pacing at 180ppm at 160mA.
At least 50 200J charge/shock or disarm cycles.
At least 9 hours of operation with ECG monitored continuously and no other options installed.
Battery Capacity
A single, new, fully-charged M3538A battery, operating at room temperature 25o C (77o F), provides enough energy for one of the following:
- At least 5 hours of monitoring, with ECG, SpO2, CO2, temperature, two invasive pressures monitored continuously, NBP measured every 15 minutes, and 20 200J discharges.
- Approximately 3.5 hours of monitoring, with ECG, SpO2, CO2, temperature, two invasive pressures monitored continuously, NBP measured every 15 minutes, and pacing at 180ppm at 160mA.
- At least 50 200J charge/shock or disarm cycles.
- At least 9 hours of operation with ECG monitored continuously and no other options installed
Battery Life
Battery life depends on the frequency and duration of use. When properly cared for, the M3538A Lithium Ion battery has a useful life of approximately 2 years. To optimize performance, a fully (or nearly fully) discharged battery should be charged as soon as possible.
Charging Batteries
The M3538A Lithium Ion Battery should be charged in either the HeartStart MRx or in a Philipsapproved battery support system. The two methods of charging in the HeartStart MRx are as follows:
Using AC power: Insert the battery to be charged into Battery Compartment A. Insert the AC Power Module into Battery Compartment B and connect to an AC power source.
Using DC power: Insert a battery to be charged into Battery Compartment A. If a second battery is in need of charging, insert it in Battery Compartment B. Connect the DC Power Module to the HeartStart MRx and the DC power source.
Once AC or DC power is applied, the External Power Indicator turns green and batteries in the HeartStart MRx charge. Batteries are charged one at a time. With the HeartStart MRx turned off and at a temperature of 25o C (77o F), a fully discharged battery typically charges to 80% of its capacity in 2 hours, and to 100% of its capacity in 3 hours. Batteries charge at a slower rate with the device turned on. Batteries should be charged at temperatures between 0o C (32o F) and 45o C(113o F).
Charge Status
You can check the battery’s state of charge by:
- periodically pushing the fuel gauge button on the battery to illuminate the fuel gauge. Each LED represents a charge of approximately 20% of capacity.
- Turning the Therapy Knob to any mode of operation and observing the battery power indicators displayed in the General Status area
WARNINGS:
- Properly dispose of or recycle depleted batteries according to local regulations. Do not puncture, disassemble, or incinerate batteries.
- Built in safety circuits can not protect against handling abuse. Adhere to all warnings and cautions in handing and using lithium ion batteries.
- Do not expose batteries to temperatures greater than 60o C (140o F). Excess temperatures may result in battery damage.
- Keep batteries away from flame and other heat sources.
- Do not short circuit the battery. Avoid placing batteries around metal objects that may short circuit the battery.
- Avoid getting batteries wet or using batteries in high humidity environments.
- Do not crush, dent or allow any deformation of the batteries.
- Do not disassemble or open batteries. Do no attempt to alter or bypass the safety circuit.
- Avoid extreme shock and vibration to the battery.
- Do not use or connect the battery to batteries of other chemistries.
