Benefits of Battery Management <ul><li>With effective battery management </li></ul><ul><ul><li>Reduce ‘warranty ‘ handling costs </li></ul></ul><ul><ul><ul><li>Replacements, call outs, uncharged labour </li></ul></ul></ul><ul><ul><li>Reduce end user downtime </li></ul></ul><ul><ul><li>Maximize equipment productivity </li></ul></ul><ul><ul><li>Increase customer satisfaction </li></ul></ul><ul><ul><li>Longer, more effective battery life </li></ul></ul><ul><ul><li>A better environment </li></ul></ul>
  3. 3. Desired Outcomes <ul><li>At the end of this session I hope to have shared with you </li></ul><ul><ul><li>How a lead-acid battery works </li></ul></ul><ul><ul><li>Different lead-acid battery types </li></ul></ul><ul><ul><li>Battery problems and their causes </li></ul></ul><ul><ul><li>effective battery charging method </li></ul></ul><ul><ul><li>ideas and practical experience on how to improve dealer and consumer battery experience </li></ul></ul>
  4. 4. CTEK – Battery Charger Specialists.
  5. 5. ‘ The Smartest Battery Chargers in the World’
  6. 6. CTEK Brief History
  7. 7.
  8. 8. Battery Knowledge
  9. 9. Purpose of the Battery <ul><li>Despite many developments in Lead Acid batteries the functions remain the same </li></ul><ul><ul><li>Provide starting power </li></ul></ul><ul><ul><li>Power accessories when engine off / idling </li></ul></ul><ul><ul><li>To stabilize charging voltage </li></ul></ul><ul><ul><li>Smooth voltage spikes </li></ul></ul><ul><ul><li>Absorb voltage surges </li></ul></ul>
  10. 10. Basic Battery Construction <ul><li>Batteries are made of five basic components: </li></ul><ul><ul><li>A resilient plastic container. (1) </li></ul></ul><ul><ul><li>Positive (lead dioxide)and negative (sponge lead) plates.(2) </li></ul></ul><ul><ul><li>Plate separators.(3) </li></ul></ul><ul><ul><li>Electrolyte, a solution of sulfuric acid and water ‘battery acid’. (4) </li></ul></ul><ul><ul><li>Terminal Posts,the connection point between the battery and whatever it powers. (5) </li></ul></ul>
  11. 11. The Battery Cycle <ul><li>Battery Discharge </li></ul><ul><ul><li>providing voltage source for load </li></ul></ul><ul><ul><li>electrolyte has high sulfuric acid content when highly charged </li></ul></ul><ul><ul><li>acid reacts with plate material to create current </li></ul></ul><ul><ul><li>acid content of electrolyte reduces </li></ul></ul><ul><ul><li>If reduced too far results in ‘flat’ or deep discharged battery </li></ul></ul>
  12. 12. The Battery Cycle <ul><li>Battery Discharge </li></ul><ul><ul><li>providing voltage source for load </li></ul></ul><ul><ul><li>electrolyte has high sulfuric acid content when highly charged </li></ul></ul><ul><ul><li>acid reacts with plate material to create current </li></ul></ul><ul><ul><li>acid content of electrolyte reduces </li></ul></ul><ul><ul><li>If reduced too far results in ‘flat’ or deep discharged battery </li></ul></ul><ul><li>Battery Recharge </li></ul><ul><ul><li>external voltage (pressure) created to push current (amps) in to the battery </li></ul></ul><ul><ul><li>acid forced out of the plates and back in to electrolyte </li></ul></ul><ul><ul><li>If not correctly controlled will lead to undercharge or overcharge </li></ul></ul>
  13. 13. The 12V Battery <ul><li>Six cells of 2.12V Each </li></ul><ul><li>Effective battery operation only at 12.45V+ </li></ul><ul><li>Readings below 12.4V require immediate corrective action to avoid ‘deep discharge’ and associated recharging problems </li></ul>Battery Open Circuit Voltage vs. State of Charge 12.72V 100% 12.45V 75% 12.24V 50% 12.06V 25% 11.89V 0%
  14. 14. Battery Types- Summary <ul><li>Robust </li></ul><ul><li>High self-discharge </li></ul><ul><li>High water consumption </li></ul><ul><li>Low self-discharge </li></ul><ul><li>Low water consumption </li></ul><ul><li>Should not be discharged more than 50% due to stratification </li></ul><ul><li>Low self-discharge </li></ul><ul><li>No water consumption </li></ul><ul><li>Deep-cycle – highest # of cycles </li></ul><ul><li>Low self-discharge </li></ul><ul><li>No water consumption </li></ul><ul><li>Deep-cycle – many cycles </li></ul>

  16. 16. Battery Problems
  17. 17. Most warranty returns are just undercharged! 178 returns evaluated Today ’s problems
  18. 18. Battery Problems – Seasonal Use Equipment <ul><li>No1 failure reason for Ride On ’s </li></ul><ul><li>Often batteries undercharged at point of delivery – resulting in battery failure within a few weeks </li></ul><ul><li>Charging equipment unable to recover / restore batteries </li></ul><ul><li>Long periods of inactivity </li></ul><ul><li>Exposure to temperature extremes in use and in storage </li></ul><ul><li>Regulator / alternator unable to charge batteries to full capacity </li></ul>
  19. 19. Battery Problems and Causes Sulphation Overcharge / Fluid Loss Stratification <ul><li>Undercharge (recovery from deep discharge, charging system) </li></ul><ul><li>Overcharge(charging system) </li></ul><ul><li>Temperature extremes </li></ul><ul><li>Parallel loads </li></ul><ul><li>Inactivity (seasonal use) </li></ul><ul><li>Lack of battery awareness at all levels </li></ul>

  25. 25. Practical Steps in Battery Management
  26. 26. Comfort Indicator Green: (≥12.7V) Battery fully charged Yellow: (<12.7V - ≤12.4V) Charging battery recommended to avoid stratification Red: (< 12.4V) Charging of Battery needed to ensure starting and avoid sulphation
  27. 27. Usage Tips <ul><li>When connected to the charger, the Comfort Indicator flashes green regardless of the charge status of the battery </li></ul><ul><li>The battery needs 30-60 minutes to ‘settle’ and to be able to show the true state of charge on the Comfort Indicator status lights. </li></ul><ul><li>For the Comfort Indicator to give an accurate reading of battery status the battery itself should not be in use. (Ignition off) </li></ul>
