Details of traction Battery Warranty

The warranty as detailed above remains valid, only if the following operating conditions are adhered to:

  1. The battery is never discharged to greater than 80% of its nominal 5 hours ampere hour capacity
  2. The battery is operated and maintained in accordance with the instruction contained in battery care document (Do’ and Don’t, below) and subsequent to instructions issued by our manufacturer
  3. The battery is topped up with specified electrolyte (De Ionized water). The electrolyte level in each cell is maintained at all times using De-ionized water. Topping up must be done at the end of charge. 
  4. The electrolyte temperature never exceeds 43° Celsius
  5. The battery only completes one discharged/charged in 24 hours during normal operations and no more than 300 cycles per year.
  6. The battery is charged using an approved charger, having the correct rating, setting and operates conditions.
  7. The battery is re-charged after the end of discharge and is left in a fully charged state. Should the battery not be required for prolonged periods, it should be fully charged before being left alone and given a re-charge once a month until required again. The battery should not be left in a discharged state.
  8. The correct rated battery capacity is used for the application. The battery is used in an approved application
  9. Notification is given within three (3) working days to CPR Battery Services or its approved agents of any defect, which  is the bases of a claim or may be reasonably expected to develop so as to register a claim
  10. Battery is only maintained by CPR Battery Services’ authorized agents and never interfered with by non approved gents
  11. The battery is not abused internally and externally or subject to excessive abnormal wear and tear
  12. It is recommended that the batteries are fully serviced by CPR Battery Services on annual bases.

CPR Battery Services and its duly appointed agents exclude all liability for any and all damages, losses, injury or expenses and whether of a direct, indirect, incidental or consequential nature or otherwise and howsoever caused and by whomsoever suffered and which may arise out of or relate to the use or inability to use the battery or any failure whatsoever to meet this warranty.

Do’s and Do Not


  1. Check the electrolyte level before charging and top it up with proper battery grade water as per BIS specification no. 1069 up to maximum level of basket type level indicator or slightly above the separators.
  2. Match the battery to the correct charger and have it checked periodically to avoid improper charging.
  3. Recharge the battery daily.
  4. Give equalizing charge to the battery once in a week after normal charge.
  1. Lift the battery compartment lid while charging, wherever possible, to assist ventilation and air-cooling.
  2. Keep the battery top and tray clean and dry at all times.
  3. Keep all inter-cell connections and bolted terminals tight and covered with a film of petroleum jelly.
  4. Check the condition of charging plug, socket and cable to avoid damage of insulation and burning of contacts. Refurbish or replace as necessary.
  5. Maintain regular reading of specific gravity, voltage and temperature of pilot cells in Record Book. Reading of all cells should be recorded once in a month.
  6. For storage of batteries in dry and uncharged condition, plug all vent holes making them airtight.
  7. For storage of batteries in charged condition, disconnect main cables connected to it and ensure that freshening charge is given to the battery once in a month.
  8. Battery charging room should be well ventilated preferable with air exhaust system to prevent the battery from over heating.


  1. Never leave the battery in a discharged state for more than a day.
  3. Do not maintain electrolyte level high above the separator level. This may cause the acid spill out during charging.
  4. Never use tap water for battery top up. Impurities in tap water can shorten the life of a battery.
  5. Never over charge the battery by recharging more frequently or longer periods than necessary to restore the capacity
    used. Over charging spoils the battery and shortens its life drastically.
  6. Avoid naked flames, sparks and smoking near a battery.
  7. Never use non-insulated tools while working on batteries. Do not wear wrist chains or loose metal bands.  This is
    necessary to avoid any short circuit or sparks.
  8. Never keep charged battery directly under sunlight or in any heated place.
  9. Never use metal vessels or jug to store battery water or acid.
  10. Never allow electrolyte temperature to exceed 43°
