Battery charging
The MVI incorporates a NiMH battery with a continuous duty cycle of greater than 6 hours’ operation. The full charge
cycle for the battery is 16 hours.
Please note:
If the units are charged from a flat battery the unit should not be charged for more than 16 hours
continuously.
If the unit requires a top up charging then 2
–
8 hours charging should be sufficient.
Recharging
Switch the instrument off. Connect the MVI battery charger to the instrument. Use only the MVI charger supplied
with the instrument. Use of an alternative charger may damage the instrument and will void the warranty. The green
charging LED lamp located immediately below the ON/OFF switch will light indicating the batteries are accepting
charge.
Only store the unit in a fully charged state.
IMPORTANT NOTE
Only use the Ion Science universal battery charger (Part Number: A-26220) provided with your instrument.
When received as new or after Service by Ion Science or an approved Ion Science Service Centre, your Instrument
will arrive fully charged. Do NOT recharge until the “LO BAT” symbol appears. Do not leave connected to the AC
power supply unless charging and certainly no more than 16 hours from a low battery message.
Excessive charging will dramatically reduce your battery life and will mean the batteries require replacing
frequently.
