8.1 Battery Pack
Caution:
•
The battery pack contains sealed lead-acid batteries, which produce small
quantities of flammable hydrogen gas.
•
Do not short-circuit the battery connections.
This option allows the sampler to operate in areas where mains power supply is not
available. The rechargeable battery pack will operate the MicroVol for 24-hours
before recharging is required.
For details on attaching the battery pack to the MicroVol-1100, see Section 2.4.2,
Assembling the MicroVol-1100.
Note: Always fully charge the battery pack after use. If the battery pack is not being
used for an extended period of time, remove the fuse and re-charge the battery
periodically (every 2 months recommended.)
The MicroVol turns the pump off automatically if the power supply (battery) voltage
drops below 11V (factory setting). The MicroVol continues to operate until the
battery discharges to about 5V, after a period of several days. Ideally, the battery
should be recharged well before this, as the battery may be damaged.
8.1.1 Charging the battery pack
The battery pack must be charged in a ventilated area. Connect the 12V battery-
charger to the Charging Port on the side of the battery pack, via the black weather-
proof connector. Do not attempt to charge the battery via the Power Connector.
The optional battery charger should be used to charge the battery pack. If a different
charger is used, it must be suitable for charging sealed-type 12-volt lead-acid
batteries. The charging current should be no more than 2.5 Amps. The charging time
will depend on the charging current. At 1 Amp charging current, the battery should be
allowed to charge for 8-12 hours, depending on the depth of discharge.
Place the protective cap over the charging socket when the charger is not connected.
8.1.2 Disposing of old batteries
The battery pack contains lead-acid batteries. After several hundred uses, battery
performance will decrease. Old batteries must be disposed of according to local
regulations. Most areas require that lead-acid batteries be recycled and have a facility
for battery disposal. Contact your local council for more information.
