2.3 Batteries
NOTE
z Use batteries at least once every month to extend their life. Charge the batteries
before their capacities are worn out.
z Inspect and replace batteries regularly. Battery life depends on how frequent and
how long it is used. For a properly maintained and stored lithium battery, its life
expectancy is approximately 3 years. For more aggressive use models, life
expectancy can be shortened. We recommend replacing lithium batteries every 3
years.
z The operating time of a battery depends on equipment configuration and
operation. For example, starting module monitoring frequently will shorten the
operating time of the batteries.
z In case of battery failure, contact us or have your service personnel replace it. Do
not replace the battery without permission.
The anesthesia machine is designed to operate on battery power whenever AC power
becomes interrupted. When the anesthesia machine is connected to the AC power source, the
batteries are charged regardless of whether or not the anesthesia machine is currently on. In
case of power failure, the anesthesia machine will automatically be powered by the internal
batteries. When AC power source is restored within the specified time, power supply is
switched from battery to AC automatically to ensure continuous system use.
On-screen battery icon indicates the battery statuses as follows:
: indicates that the batteries operate normally. The solid portion represents the
current charge level of the batteries in proportion to its maximum charge level.
: indicates low battery and the batteries need to be charged.
: indicates too low battery and the batteries need to be charged immediately.
The capacity of the internal battery is limited. If the battery capacity is too low, a high-level
alarm will be triggered and the [Low Battery Voltage!] message displayed in the technical
alarm area. In this case, apply AC power to the anesthesia machine.
