Battery LifeTester
ELK-BLT v.2 Mhos Meter
The NEW and improved ELK-BLT v.2 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 Ch

ELK - BLT Instructions 1. Disconnect the battery from it’s 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 blank indicates 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 displa

ELK - BLT Instructions How Temperature affects a Battery Generally speaking, temperatures below 72F degrees tend to slow down a battery’s internal activity, causing a significant decrease in the Mhos (conductivity) reading as the temperature falls. Cool temperatures (not below freezing) will tend to prolong a battery’s life. Temperatures above 72F cause a battery’s internal activity to accelerate, but with only a slight increase in the Mhos reading. Warm temperatures will tend to dry out and d

ELK - BLT Instructions Accumulating Trend Analysis over a Period of Years Trending of periodic Mhos measurements can yield valuable insights for estimating the remaining life of the battery. Suppose that a 4.0 Ah battery has been in service for three years and that the LifeTester measurements after the firstyear was 90 Mhos, 85 Mhos after the second year, and 80 Mhos after the third year. Since the battery is still at 80 Mhos and is dropping an average of 5 Mhos per year, it is highly likely
