Running the Nippy+ Range on Battery Power
The Nippy + range may be powered from the mains, external battery or internal battery.
When running on mains, the ventilator will recharge its own internal and/or external battery. Charge time is normally around 8 to 11 hours, per battery, depending on the ventilator settings.
Batteries will also be charged when the Nippy is connected to the mains supply but not running. Leave connected to the mains supply in between periods of use to keep the batteries charged or to recharge ready for the next use.
When an external battery is connected to a machine, which has an internal battery, each battery is charged to approximately 90%, starting with the internal one. Then both batteries are fully charged starting with the internal one. When the battery(s) are charged, the charge will terminate and the battery will be monitored to maintain its charge.
NOTE: Basic models, not fitted with the internal battery have no reserve power unless an external battery is connected.
The ventilator will select its power source, according to the power available, in the following sequence:-
1. – Mains Electricity
2. - External Battery (if connected)
3. – Internal Battery (if fitted)
In order to save battery power, the ventilator will always run on mains electricity if it is present.
If the mains fails or is not connected, the ventilator will select external battery as the next choice. The external battery, if present, will always be run flat before the internal battery is selected.
If there is no external battery, the ventilator will switch to its internal battery. If there is no internal battery the ventilator will shut down and alarm.
Battery Run Times
Battery run times are dependent on the ventilator settings and the amount of leak. High pressures and /or high breath rates use power and therefore shorten run times.
Large leaks use power and shorten run times. The expected run time can be displayed on screen. Double press the SET button to display a bar graph of run time. The time for each battery connected will be calculated, according to the ventilator settings, and shown on the screen.
The run time may be as long as 12 hours for low values of CPAP with only moderate leak, or as short as 4 hours for Pressure Support at maximum pressure with quite severe leaks.
Battery run times will typically be 20% more in IPPV mode because of the absence of the exhale port leak. Run times will be shortened by higher breath rates and/or higher EPAP levels.
Low Battery Alarm
When the battery is almost depleted the battery icon will flash and change colour to red.
When the battery is depleted an alarm will sound, accompanied by an on screen message, “Battery Power Running Low”.
When battery power reaches a critical level, the alarm will change to a continuous tone and the on-screen message will change to “Battery Power Exhausted. About to switch off. Connect to Mains Power Now”.
After auto power off, the constant alarm will continue until the Mute is pressed.
Internal Battery
Battery Test
Test the battery if the running time seems low, a fault is suspected, or to confirm that the battery is good.
Ensure the battery is fully charged.
Run the ventilator from the battery until the low battery alarm operates and record the running time. Look up run time in the table. If the battery is not achieving minimum run time replace it.
If the battery is good, fully recharge it immediately after testing.
Hints and Tips For Reliable Operation
Always make sure that the battery is fully charged before use.
If you are in doubt about your battery’s state of charge, charge for at least 24 hours.
If running time suddenly seems considerably shorter than normal, make sure that the battery is fully charged.
Check the running time of your system regularly.
Most reported problems arise from incorrect battery charging.
Battery Life
The end of life is defined by the maximum running time falling to 75% of that of a new battery. For a battery that is used occasionally service life is 2 years. Replace the battery when running times drop below those indicated or after 2 years.
Internal Battery Replacement
The internal battery should be replaced every 2 years or after 10000 hours use or if the run times are shorter than expected. The user cannot replace the battery. Refer ventilator to suitably qualifiedtechnical personnel for battery replacement.
DO NOT attempt to dismantle the ventilator
DO NOT attempt to fit any battery other than the approved type. Fitting of any other type of battery could lead to personal injury and damage to the ventilator.
Disposal of depleted batteries
Depleted batteries may be disposed of in line with local authority regulations.
Recommended batteries for use with Nippy+ range:
Replacement internal battery, part number 0913
External battery, part number 0911
Use only the recommended batteries. See “battery care” section for full instructions.
External Batteries
An external battery may be used to increase the running time. This battery is essentially the same as the internal battery and will power the ventilator for the same time, depending on settings and leak
External Battery, part number 0910.
External battery charger part number 0911
These batteries should never be used to run any other type of equipment.
DO NOT attempt to connect any battery other than those supplied by the manufacturer. Use of any other type of battery could lead to personal injury and damage to the ventilator.
Instructions For Use
Connect the battery to the Nippy+ range Aux Power input.
The Power light will illuminate.
Switch on the Nippy jnr+. The Ext Batt light will flash and a “Running on battery power” message will be displayed on the Nippy jnr+ screen. Press the alarm mute button to hide the message.
To disconnect a battery: Always switch off the ventilator first. Press the plug release button on the connector and withdraw the connector
To Charge a Battery
Leave the battery connected to the Nippy jnr+ whilst it is connected to mains electricity. Alternatively, charge with the battery charger as follows:-
Place the charger on a smooth flat surface.
Connect the charger to the battery socket before switching on the mains power.
Connect the mains plug to the AC supply and switch on.
Leave on charge until the charged / ready indicator lights. Batteries may produce explosive gases during charging. Always charge away from sparks or sources of ignition.
Do not smoke near a battery whilst charging. Disconnect the mains power before disconnecting the battery from the charger. Batteries may be left connected to the charger until required for use.
Safety
Warning! High voltages exist inside the charger.
DO NOT remove the cover. Return to B & D Electromedical if a fault occurs.
DO NOT expose to water or dust.
DO NOT cover the charger whilst in use
Ensure that the mains lead is not damaged.
DO NOT attempt to charge any other type of battery with it.
Battery pack cleaning
To clean, wipe the exterior of the case with a soft cloth moistened with water.
Battery Care
DO NOT use any other type of battery charger. This could lead to damage to the battery and personal injury.
The battery should be recharged as soon as possible after use.
This type of battery does not suffer from the memory effect that is widely talked about and does not need to be fully discharged before charging.
Batteries like to be used. A new battery may require several charge/discharge cycles before it reaches its maximum performance. The same applies to a battery that is only used occasionally with long periods in storage.
Battery Life
The end of life is defined by the maximum running time falling to 75% of that of a new battery. For a battery that is used occasionally service life is 2 years. Replace the battery when running times drop below those indicated or after 2 years.
Battery Storage
This type of battery is best stored partly charged. A battery that is not in use will slowly discharge. This rate of discharge increases with temperature. Ideally the storage temperature should be above -20oC and below 20oC. It must be below 40oC. After storage in a cold environment allow 24 hours for the battery to reach room temperature before use. Fully charge the battery every 2 months.
Battery Test
Test the battery if the running time seems low, a fault is suspected, or to confirm that the battery is good.
Ensure the battery is fully charged.
Run the ventilator from the battery until the low battery alarm operates and record the running time. Look up run time in the table. If the battery is not achieving minimum run time replace it.
If the battery is good, fully recharge it immediately after testing.
Hints and Tips For Reliable Operation
Always make sure that the battery is fully charged before use.
Do not switch off charger until battery is fully charged.
Avoid the temptation to give the battery “a quick boost”. This is of no benefit.
If you are in doubt the state of charge, charge for at least 24 hours.
If running time suddenly seems considerably shorter than normal, make sure that the battery is fully charged.
Do not charge your battery near sources of ignition.
Check the running time of your system regularly.
If you have more than one battery, use them in rotation.
Do not use if any of the cables or components show any sign of damage. Most reported problems arise from incorrect battery charging.
