b'BATTERY LIFETESTERA 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 batterys health and life expectancyThe BLT operates as follows: For each battery brand and size installed, 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 When the current Mhos reading has reached at or around 71% of the original baseline then it is time to consider replacing the batteryCompact, low cost, and easy to use3 digit displayDoes not discharge or damage the batteryIncludes self-adhesive test data labels for recording battery readingsIncludes hard shell, protective carrying casePowered by the battery under test - warns when the battery voltage is too low for testingRoHS CompliantSize 44 x 3 x 115 Coated clips to connect to batteryLifetime Limited WarrantyELK-BLTBattery LifeTester 7 62158 80002 3ELK-BLTLABELS POWER PRODUCTSSelf-adhesive Test Data Labels, 100 Pack 7 62158 80010 8POWER DISTRIBUTION UNITSELK-PD9HCThese convenient modules distribute power from a single AC or DC source to up to 9 outputs for centrally powering cameras, PIR\'s, photobeams, etcTerminal blocks & 21mm DC power jack for power connectionAuto-resetting PTCs help prevent a shorted output from disabling the other outputsMaster power on/off switchVisual LED power indicators or each outputConvenient test points for measuring total current drawOutputs may be paralleled to increase max current draw from each outputMax current draw: 400mA from each outputMax combined current draw: Not to exceed input power source or 36ARequires a 6 to 30 volt AC or DCpower source (not included)Color:White 7 62158 30009 7Size: 65" x 43" x 2"RoHS CompliantLifetime Limited Warranty69'
