To test single batteries connected in parallel, it is nec-
essary to disconnect one terminal to test the battery
accurately. Testing a group, as shown in the illustration,
takes into account all batteries and their inter-con-
nections. This can be done with 6v and 12v systems,
where the total AH capacity does not exceed 200AH.
Verify that the tester is set to the proper MODE for total
amp-hour capacity. A reading below 70% indicates
one or more defective batteries or high resistance
inter-connections within the group.
Batteries under Charge
It is not recommended that batteries be tested when
connected to a charging system. Disconnect the char-
ger for several minutes then test the battery three or
more times.
Operating Characteristics & Tips
1) When the power switch (ON/OFF) is turned on, the
MODE will be set to the last one used.
2) The internal cooling fan will run while test leads
are connected to a battery in the following three
MODES: 8V [20+AH] and 12v [16-50AH, 50+AH].
NOTE: To insure proper cooling, keep side and
bottom air vents unobstructed.
3) The MBT-LA2 will turn off automatically after 20
minutes of no test activity, provided it is NOT con-
nected to a battery. To restart, simply cycle the
power switch OFF then back ON.
