Product Installation Document
1 Overview
The Honeywell HPBLT “Battery LifeTester” is a compact, easy to use Mhos meter for testing 12 Volt rechargeable
batteries. Unlike ordinary testers which only measure static criteria, the LifeTester measures internal conductivity, which
is the best indicator of a battery’s health and life expectancy. The conductivity value, expressed in Mhos (the inverse of
Ohms or resistance), is easily compared to benchmark readings from the included Mhos Chart. The chart then categorizes
the battery condition as “Best”, “Good”, “Weak” or “Bad”. Every battery type has a characteristic Mhos value when it is
brand new and fully charged. The LifeTester is powered by the battery under test and automatically warns when the
battery voltage is too low for testing.

4 Installation Instructions
1.
Disconnect the battery from its equipment.
2.
Connect the BLACK test clip to the Negative (-) battery terminal and the RED to the Positive (+) terminal. (For
accurate readings, the test clips must be tightly clipped directly to the battery posts, not to the battery bolts.) “Err” or
a blank screen indicates that battery voltage is too low for testing or a test clip connection is loose. Try charging the
battery or reconnecting the test clips.
3.
The voltage of the battery will display briefly. A new battery, out of the box, will generally read around 12.6 Volts. A
fully-charged battery should read between 12.6 Volts and 13.5 Volts. “- - -” indicates a test in progress.
4.
The Mhos (internal conductivity) reading of the battery will display within six seconds.
5.
Refer to the Mhos Chart. In the “Ah” column, find the battery size. Follow across the row to find the closest match
to it’s Mhos reading. The column heading and color code indicates the test results. NOTE: The Mhos chart printed
on the BLT is best suited for batteries under charge and at room temperatures of around 72°F. This covers most
batteries, even in cold basements or buildings, since the battery will be kept warm by the recharging and by being
inside the electronics enclosure. However, since cooler temperatures can significantly lower the Mhos reading of a
battery, this instruction manual has a more extensive Mhos chart with columns for evaluating batteries that are being
