PRAG provide One-Year warranty on all batteries installed by us and our AUTHORISED distributors.

PRAG batteries are of the highest quality and designed for long life. When used properly, the batteries can last up to three years. Please note that battery longevity is determined by usage style and adoption of recommended battery banks for each class of inverter. We will not be liable for poor usage of battery and non-compliance to specifications.
Warranty only applies when batteries are used according to the specifications mentioned herein:

  1. Batteries must be returned unopened, without physical damage and in good condition.
  2. PRAG Tubular GEL batteries are designed for Solar Installations and warranty only applies when deployed as such.
  3. PRAG AGM-GEL/GEL/CARBON and FLOODED batteries are designed for energy storage and regular warranty terms apply on proper application and usage.
  4. The warranty period on the battery being recharged/replaced shall commence from the date of sale of the original battery as stated in the original invoice and not from the date of replacement.
  5. In the event of any particular battery model being phased out, the company reserves the right to provide another model of the same capacity as settlement of Warranty.
  6. All liabilities under this Warranty shall cease if the Battery is:
    1. Transferred to any other party other than the original buyer; and  
    2. Used in any application other than that for inverter and the initial loads being accommodated.
  7. This warranty does not cover:
    1. Defects/damages to the battery caused by accidents, fire, natural calamities like earthquake, flood, etc. beyond the control of the Company, faulty electrical systems, negligent maintenance, incorrect charging or improper handling/maintenance by unauthorized personnel or third parties, willful abuse, destruction by fire.
    2. Breakage of container and cover or breakage and deformation of terminal duets through
    3. Mechanical shocks and hammering.
    4. Recharging which shall be billed as extra.
    5. Failure of battery due to over discharge or over charge.
    6. Battery operated/abandoned in deep-discharge status for long period.
    7. Installations done in airtight environments and places that are susceptible to humidity due to customer’s choice and insistence.
    8. Exposure to excessive heat or cold temperatures.
  8. In case of warranty claim, the invoice/receipt/delivery notes (original) must be produced without which claim will not be entertained.
  9. Where refund is required, battery usage period is pro-rated over One-Year of the warranty terms and monetary equivalent based on purchase value will be given to conclude transaction.


The right to determine whether a battery needs repair or total replacement lies with the Company. In cases where the battery is replaced, the defective battery being replaced becomes the property of the Company and no scrap rebate will be given.


  1. Load: Load on the inverter must be reduced to a minimum as much as possible. You are advised not to use more than 25% of the rated maximum capacity of the inverter.
  2. Discharge: Batteries should not be fully discharged. Maximum recommended Depth of Discharge is 50%. Batteries must be recharged daily with Generator/PVS whenever NEPA/PHCN is unavailable.
  3. Charging: Always charge your batteries for longer periods. Completely discharged batteries will need between eight to 10 hours to charge effectively. Charging below this period often will reduce the lifespan of your batteries and negatively affect efficiency and run time.
  4. Leaving Batteries Discharged for Long Days: Do not leave your batteries completely discharged for days. This leads to sulfation which is irreversible and reduces battery capacity and life. Always ensure your batteries are fully charged before travelling or if batteries will not be used for a long time. Leaving a battery completely discharged for days will reduce battery life or totally destroy it.
  5. Mixing of Different Brands of Batteries: Do not mix different brands of batteries together. This will kill the set of batteries as quickly as possible. Do not mix old and new batteries. Please ensure that batteries are changed per set and not otherwise to avoid poor battery performance and reduced life cycle.


NOTE: Back up time or autonomy reduces as battery usage (period) increases. Life cycle depends on various factors such as frequency of charge / discharge, depth of discharge, quality of charge and general usage.
