ensure uninterrupted operation, the packs should be
replaced daily or within the time period listed above.
If a battery pack has been forgotten and is left connected
to a running DustTrak
™ monitor
,
the extended-life battery
will automatically quit delivering power after its voltage
drops below 10.5 V. This cutoff provides protection to the
battery pack, which will extend the lifetime of the pack.
NOTICE
The logged data
WILL NOT
be lost even if
both
battery
packs lose power.
Battery Pack Life
Battery packs will age over time per usage and care. The
battery packs will last 180 to 200 cycles on average. One
cycle being defined as one battery pack discharge and one
recharge process. With optimal use and care the life of a
battery pack may possibly be increased beyond 200
cycles. To obtain optimal battery health, keep battery
packs on charge in a cool, dry, and well-ventilated area
while
NOT
in use, and recharge battery packs immediately
after use. This assumes that the batteries are being used
to run a DustTrak
™ Environmental Monitor every day and
that they are properly cared for and rotated daily.
Replacement battery packs may be ordered from TSI
®
.
If battery packs are stored off of charge for durations
longer than 30 days then longer charge times and shorter
run-times may result due to degraded battery health.
Battery pack health will diminish at a much more rapid
pace if
NOT
recharged immediately (within one hour
maximum) after use.
It is important to remove a battery pack from service if
signs of diminished run-time or longer charge time are
observed. These are signs of battery pack aging and poor
general battery health. A battery pack in good health will
take near 8 to 9 hours to fully charge. A battery pack that
provides 30% less product run-time than expected is ready
to be removed from service. If a given battery pack
provides a run-time of 17 hours or less for the DustTrak
™
monitor, or a run-time of 10 hours or less with the heated
inlet accessory, the battery pack should be removed from
service and properly recycled in accordance with local
environmental regulations.
Battery Pack Health Status Check
TSI
®
highly recommends consistently monitoring the
health of all battery packs in possession. This status check
is intended to help with that process and should be
performed in addition to the use and handling instructions
listed within this manual. This status check is not intended
as a replacement for any other use and handling
instructions as all instructions are important to follow to
maintain battery health and to get the maximum life from
battery packs. It is important to follow the following process
to help to identify a battery pack that is no longer in good
health and needs to be recycled.
Battery Pack Health Check Procedure
1. Check the battery pack visually for any signs of
bulging or abnormal appearance.
2. Connect the battery to the TSI
®
Battery Charger Part
#801809.
3. Plug in power to the charger.
4.
Keep the battery pack on charge until the charger’s
“GO” LED light is lit green indicating that the battery is
now completely charged.
5. Disconnect power from the charger.
6. Disconnect the battery pack from the charger.
7. Let the battery pack rest (off the charger) for at least
one hour.
8. Using a DC Volt
Meter, connect the
“red” (positive) test
lead of the meter to
the battery pack
output connector at
the conductor
located closest to the
triangle-shaped side
of the connector.
Please see the
illustration.
9.
Connect the “black” (negative) test lead of the DC Volt
Meter to the battery pack output connector at the
bottom conductor as illustrated in the picture above.
10. Record the voltage measured by the DC Volt Meter.
11.
If the measured voltage is ≤12.9 volts, this battery
pack is no longer in good condition and should
NOT
be charged. Remove this battery from service and
recycle the battery according to local, state, or
federal regulations.
12. However, if the measured voltag
e is ≥13 volts, this
battery is in good operating condition and is able to be
charged unattended, using the TSI
®
Battery Charger
Part #801809.
