External Batteries
Two types of battery are available for running the Nippy 3. Back-up batteries and Mobility batteries. Each has its own dedicated charger. Batteries and chargers are not interchangeable
These batteries should never be used to run any other type of equipment.
Instructions For Use
Connect the battery to the Nippy 3 Aux Power input. The Power light will illuminate. Switch on the Nippy 3. The Ext Batt light will flash and a “Running on battery power” message will be displayed on the Nippy 3 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
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.
For best results leave battery connected 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 an ordinary car battery charger. This type of charger may damage the battery and will almost certainly shorten its life. The battery should be recharged as soon as possible after use. The battery may be left on charge with the supplied charger indefinitely. 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. The performance of all lead-acid batteries falls with temperature. The times stated below refer to ambient charging and operating temperatures of 20oC.
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 must always be fully charged before storage. 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 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. Leave your battery on charge when not in use. Do not charge your battery near sources of ignition. Check the running time of your system from time to time. 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.
