1 CBC Automotive n Operation n Service n Diagnosis Battery

2 CBC Automotive Battery n Source of Energy n Reserve while running n Stabilizer

3 CBC Automotive Battery n Converts chemical energy into electrical energy

4 CBC Automotive Cells n # of cells n Cell voltage n How cells are connected

5 CBC Automotive Chemistry n During charging and discharging

6 CBC Automotive Charged n + = Pb O2 (Pure lead peroxide) n - = Pb (Sponge lead) n Solution = H2 SO4 n Solution of Sulfuric acid & water

7 CBC Automotive Discharging n + = PbSO4 n - = PbSO4 n Plates turn to Lead Sulfate n Solution = H2O

8 CBC Automotive n Why do batteries freeze?

9 CBC Automotive Reversing the cycle again

10 CBC Automotive Battery Gassing n During discharge n During charge

11 CBC Automotive Batteries do blow up

12 CBC Automotive Precautions n Remove grd. term. first n Connect grd. last n Jumper/charger on block n Corrosive

13 CBC Automotive Precautions n when jumping a battery n when using a charger n when disconnecting a cable n when using any flame source

14 CBC Automotive Construction

15 CBC Automotive n Positive plate n Negative plate n Separator n Grid

16 CBC Automotive Conventional Battery

17 CBC Automotive pluses Maintenance Free - pluses n Larger plates n Resistance to overcharging n Longer shelf life n Higher cold cranking rate

18 CBC Automotive faults Maintenance Free - faults n Grid growth - hot n Can’t take being deep cycled n Low reserve capacity n Drain quick with a parasitic load n Shorter life

19 CBC Automotive Low maintenance

20 CBC Automotive Hybrid Batteries n Calcium in the neg. plates n Antimony in the pos. plates n Allows deep cycling n Marine n Golf carts etc..

21 CBC Automotive Recombination n Has gel instead of liquid n Result - no gassing n higher cell voltage.1 n cold starting

22 CBC Automotive Terminals n Post n leakage n Side Terminal n “L” terminal n specialty and import

23 CBC Automotive TemperatureTemperature 0’ = 40%0’ = 40% ChargeCharge Plate areaPlate area ImpuritiesImpurities GassingGassing

24 CBC Automotive Causes of battery failure

25 CBC Automotive failure Causes of failure n Electrolyte level n Overcharging n Undercharging n Corrosion n Cycling n Temperature n Vibration

26 CBC Automotive State of charge testing

27 CBC Automotive Hydrometer n with float n with balls

28 CBC Automotive Open Circuit Voltage Test n Sealed batteries n Remove surface charge n 12.6 = fully charged n 12.4 = 3/4 charged

29 CBC Automotive Must be 3/4 charged before doing a battery capacity test A battery Must be 3/4 charged before doing a battery capacity test

30 CBC Automotive Check the temp. Before load testing - Check the temp.

31 CBC Automotive Before load testing you must know what the battery is, or should be rated at The right battery for the vehicle

32 CBC Automotive Ratings n Ampere-hour rating n Cold cranking rating n Reserve capacity rating n Watt hour rating

33 CBC Automotive Capacity Test Three times the ampere-hour rating Formula for load testing

34 CBC Automotive Cold cranking amps divided by 2 Formula for load testing

35 CBC Automotive Three minute charge test sulfated Tests for a sulfated battery n 40 amps for three minutes below n Should be below 15.5 volts

36 CBC Automotive Battery Drain test or System drain test everything off n Ammeter in series at the battery post with everything off n GM.1

37 CBC Automotive Battery leakage test n Volt - at negative post n Volt + across battery n under 10 volts

38 CBC Automotive Fast / Slow charging

39 CBC Automotive Battery cleaning

40 CBC Automotive That's all folks
