TM 9-6115-668-131.Measure no load voltage Uo:a. Switch off load resistors of lead battery tester.b. Apply test probes with correct polarity to terminals (+ and -) of battery (38, 39).c. Read off no load voltage Uo value displayed on lead battery tester.NOTElif no load voltage Uo < 12.5 V, charge battery with charger vi J3slave receptacle 24 V Connector.lif the battery gets very hot during charging, It is defective and mustbe replaced.lWhen no load voltage Uo>12.5 V, measure load voltage UB.2. Measure load voltage UB:a. On the lead battery tester, activate the number of load resistors required for the particular typeof battery.b. Apply test probes with correct polarity to terminals (+ and -) of battery (38, 39).c. Read off load voltage UB value displayed on lead battery tester.NOTElif load voltage UB > 10.0 V, battery is at least 40% charged, and itshigh current load capability is sufficient for starting.lif load voltage UB < 10.0 V, charge battery with charger via J3 slavereceptacle 24 Connector.1.Using lifting handles (36), insert batteries (38, 39) individually into lower part (40) of battery setholder.2.Install terminal connector of battery cable (33) on negative terminal of battery (38) and tighten nut(34)3.Install terminal connector of battery cable (33) on positive terminal of battery (39) and tighten nut(35).4.Install terminal cover caps (31, 32).5.Place upper part (37) of battery set holder on batteries (38, 39).6.Swing clamping device (41) into place, hook into upper part (37) of battery set holder, and tightenscrews (42).4-182
