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 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 test in process, please wait. 4. The Mhos (internal conductance) reading of the battery will display within 6 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 72F degrees. 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 adversely affected by 62F, 52F, and 42F degree environments. Also see How Temperature affects a Battery 6. For future reference mark the battery with the Voltage, Mhos reading, and test date. Automatic Shutdown If the LifeTester is left connected to a battery for more than 30 seconds after the test is complete, it will automatically shutdown to conserve battery power. Disconnecting and reconnecting a test lead will restart the test procedure. Recording Battery Readings LifeTester measurements should be taken and recorded periodically. The popular method is to record the information onto self- adhesive labels placed directly onto the battery. A supply of these labels is included with the tester. Additional labels may be ordered in packs of 100 by specifying part number ELK-BLT LABELS. This information will be valuable in future tests for trending analysis. The recorded data should include: A. The Date of the test. B. The Battery Voltage reading. (optional) C. The Mhos reading. A new “fresh out of the box” battery that has not been charged should have a Mhos value in the high side of the Good column and quite possibly into the Best column. See the Mhos chart. If the reading is considerably lower, charge the battery for at least 24 hours and then retest. Battery performance degrades over time due to use and abuse, and may be impacted by many factors like depth and frequency of discharge. The higher the Mhos value the more current the battery can deliver. Therefore, a new 7 amp-hour battery will have a higher Mhos value than a new 4 amp-hour battery of the similar construction. Instructions ELK - BLT Instructions ELK - BLT 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 degrade a battery much faster than normal. 100 F degrees = 105 % of normal Mhos (conductivity) 52 F degrees = 87 % of normal Mhos (conductivity) 72 F degrees = 0 % no adjustment 42 F degrees = 82 % of normal Mhos (conductivity) 62 F degrees = 92 % of normal Mhos (conductivity) 32 F degrees = 76 % of normal Mhos (conductivity) ELK Products is not responsible for misprints or errors. These Mhos values are benchmark averages, created from fresh samples of major brand batteries. If you find consistent, minor variations in readings from multiple samples of a battery, it’s likely due to manufacturing differences. However, if the readings are excessively low, the battery is not as good as the benchmark average. If this chart does not include...
