CAUTION : Because of the possibility of personal
injury, always use extreme caution when working with
!
batteries. Follow all BCI (Battery Council International)
safety recommendations.
WARNING : (Required by California Prop. 65) Battery
posts, terminals, and related accessories contain lead
!
and lead compounds, chemicals known to the state of
California to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.
PRIOR TO TESTING THE BATTERY
Testing Out-of-Vehicle:
Clean battery posts or side terminals with a wire brush. For
testing side-post batteries, install and tighten lead terminal stud
adapters. Failure to properly install stud adapters, or using
stud adapters that are dirty or worn, may result in false test
results. Do not use steel bolts.
Testing In-Vehicle:
Turn off vehicle and all accessory loads. Testing with the
ignition switch on or vehicle loads on may cause
inaccurate readings.
If vehicle was running prior to testing, turn on headlights for
30 seconds to remove surface charge. Let battery rest for one
minute to recover before starting to test.

PBT Testing Advantage:
The PBT-100 digital battery tester uses Midtronics patented
conductance technology to determine if the battery is good or
bad, even when discharged. This means you can safely, quickly,
and accurately test a battery anywhere.
Conductance Technology:
Conductance is a measurement of the battery's ability to
produce current. To measure conductance, the tester creates
a small signal that is sent through the battery, then measures a
portion of the AC current response. Conductance is a measure
of the plate surface available in the battery, which determines
how much power the battery can supply.
As a battery ages, the plate surface can sulfate or shed active
material which adversely affects its ability to perform. In addi-
tion, conductance can be used to detect cell defects, shorts,
and open circuits which will reduce the ability of the battery to
deliver current.
Using conductance, Midtronics testers are able to determine
the battery's true state of health. A conductance tester does not
put a load on the battery, which means no heat or sparks during
testing. This makes the PBT-100 safe to use anywhere and it is
sized to take everywhere!
