  • The ELK ELK-BLT v.3 Battery Mhos Meter is a compact, easy to use service tool for testing 12 Volt rechargeable batteries. The BLT measures internal conductivity (Mhos), which is the best indicator of a battery's health and life expectancy. Mhos happens to be the inverse of Ohms (conductance as opposed to resistance). The BLT operates as follows: For each battery brand and size installed you should start by measuring and recording a baseline Mhos reading. Then, during any service call or inspection simply measure and record the current (most recent) Mhos reading. Always compare the current Mhos reading with the original reading. Self-adhesive test data labels may be used for recording each inspection. When the current Mhos reading has reached at or around 71% of the original baseline then it is time to consider changing the battery. The BLT includes a reference chart on the back with numbers equating to Mhos readings for common security industry battery sizes.

    The BLT receives its operating power from the battery under test and automatically warns when the battery voltage is too low for testing.
