  • 1. BATTERY -B. Prasad Chartered Engineer amieclub@gmail.com
  • 2. TYPE OF BATTERY  Vented / Flooded Lead Acid batteries  Sealed maintenance free batteries/Valve Regulated Lead Acid  Nickel Cadmium (Ni-cd) batteries
  • 3. Lead acid battery
  • 4. Battery cut view
  • 5. Connection 36 V 12 V
  • 6. Vented / Flooded Lead Acid Batteries- two type Tubular  Normal life 8-10 years  Nominal cell voltage is 2V/cell.  first charge at 2.6 to 2.7 V/cell.  Away from delicate electronic equipments.  It needs separate room/racks with acid proof tiles for installation  regular maintenance to check specific gravity, to add water and acid  initial charging take about 55 to 90 hours. Plante  normal life 15-20 years.
  • 7. VRLA/SMF type Lead acid battery  Being sealed, these batteries do not emit any fumes  Normal life 3-5 years  Nominal cell voltage is 12V/cell.  Float voltage 13.8 Volts  SMF batteries should not be left in totally discharged state more than 72 hrs.
  • 8. Nickel Cadmium Batteries (Ni- Cd)  Normal service life is 20-25 years.  Nominal cell voltage is 1.2 V/cell  Initial cost may be approximately three times  Used in hazardous environment such as chemical, fertilizer, cement industry.  Batteries occasionally demand boost charging, 1.4 V/cell
  • 9. APPLICATION OF BATTERY  UPS  Battery charger in switchgear  Inverter  Automobile  Solar plant  Solar light
  • 10. ACT FAST AND INITIATE FIRST  बड़ा    सोचो         तेजी से सोचो व     सबसे पहले सोचो  िवचारो     पर िकसी का       एकािधकार नही होता.   ----  धीरभाई अमबानी
