Charging Battery
Note:
Only charge or test Mid-Continent Instrument Company battery P/N’s 9015607 and
9016925 with the TT43 Battery Tester/Charger. Charging or testing other types of
batteries may damage the charger.
Plug the battery (P/N 9015607 or 9016925) into corresponding connector either labeled “9015607
ONLY” or you may plug the battery into the connector labeled with “9015607” or “9016925” with
the charger powered on. If you have chosen to plug the battery into the connector labeled
“9015607” or “9016925” then you will need to ensure that the center toggle switch is moved to the
appropriate position selecting which battery, either 9015607 or 9016925, to be charged or tested.
If the battery is not fully charged, the battery will immediately start charging with the screen
displaying “CHARGING”. Full charge may take up to 6 hours depending on battery type. The
system will charge either two 9015607 batteries simultaneously or one 9015607 and one 9016925
simultaneously.
When full charge is reached, the screen will indicate “FLOAT”. When this is indicated the charger is
now in float mode and will maintain the Battery in full charge condition.
IMPORTANT BATTERY INFORMATION
A)
Do not charge a battery that shows signs of leakage or corrosion.
B)
Do not charge a battery at extreme temperatures. It is recommended to charge the
Battery in a moderate temperature environment, avoiding extremes of either hot or
cold.
C)
The Battery can be left on float charge indefinitely. Float charging will maintain the
best possible conditions to maintain the life of the battery.
D)
The battery may be safely charged in any physical orientation.
E)
If battery has charged for 9 hours or more but the LCD still indicates “Charging”,
unplug the battery and check battery voltage to see if it is 20.5VDC±0.5V. Plug battery
pack into the charger and wait for one minute, if the system indicates “FLOAT” and the
current is 25mADC or less, the battery is already fully charged. Proceed with Section 6
Testing Battery Capacity if this test has not been performed prior to the charge. (Use
this method to verify a full charge battery ONLY IF “FLOAT” is not indicated and
current is not less than 25mADC after charging for 9 or more hours.)
