Battery Replacement
Caution • Before you remove the battery, perform a monitor hard shutdown to ensure that
all patient and system data is saved in memory.
• Dispose of used batteries in an environmentally responsible manner. Do not
dispose of the battery in normal waste containers. Consult your hospital
administrator to find out about local arrangements.
Replace the battery if the following conditions occur:
• After reconditioning, if the Max Error exceeds 2%.
• If the battery does not recharge to full capacity after four reconditioning cycles.
• If the battery cycle count exceeds the recommended limit of 300 cycles.
• If the battery is older than three (3) years.
Warning The risk of battery failure increases with age, when a battery remains in use past
300 charge-discharge cycles or 3 years. Such failures can result in overheating that
in rare cases can cause the battery to ignite.
