Battery Care and Maintenance
The Philips 40488A sealed lead-acid batteries used in the V24CT provide
optimum performance and battery life when properly cared for. Proper
handling of batteries is essential to the life of the battery and safety of the
user.
Storage • Store batteries in a cool dry area. A refrigerator is an excellent place
to store batteries. Allow batteries to return to room temperature
before charging or use.
• The charge in the batteries gradually deteriorates even during
storage. They will self-discharge 4-5% for each month in storage at
25°C.
• Batteries should be stored in a fully charged state.
• A stored battery loses capacity over time. To minimize loss of
capacity recharge battery at least once every 6 months. Batteries
can be charged in the monitor or by using a battery charger.
Note— Recharge the batteries after using them. It is especially important
to avoid allowing the batteries to stay in a fully discharged state for long
periods of time. Simply plug the monitor into AC line power after
transporting a patient or when the monitor is not in use. If possible, avoid
discharging the battery completely.
• Replace batteries with known charged batteries in the following
conditions:
– Batteries discharge quickly when being used
– Batteries’ runtime after first “RECHARGE BATTERIES”
alarm is less than ten minutes
– Batteries do not charge to full capacity (indicated by the
monitor's battery fuel gauge)
