General Product Limited Warranty

Lead Acid Based Portfolio

Power-Sonic Corporation (Power-Sonic) warrants its products against defective workmanship and materials for the term defined below by product series and application. The period is defined from the date of purchase.


  • The battery selected by the user must be of the correct size, design, and capacity for the intended application. Failure to do this will invalidate the warranty.
  • The batteries should be paired with a suitable charger designated for the technology. Incorrect selection of charger and/or failure to follow the correct charging that conforms with Power Sonic’s charging recommendations will void the warranty.
  • Series and Parallel strings must be limited to five strings without the expressed written approval of Power-Sonic.
  • The battery should be installed and operated at an average ambient temperature not exceeding 77°F (25°C). The warranty period shall be reduced by 50% for operating temperatures that exceed on average above 95° Fahrenheit (35° Celsius).
  • The batteries are subject to IEEE Standard 1188 Acceptance Test at time of installation. If they do not meet both, or either, the standards and the published Power-Sonic specifications. The end user must notify Power-Sonic and request further instructions.
  • 2-volt cells are designed to be installed vertically. Any installation with an orientation other than vertical, with terminals on top, will be void of warranty.
  • Dismantling and moving batteries to a different location will void the warranty unless Power-Sonic is contacted and provides written consent of such action.
  • Battery annual maintenance records must be kept manually or electronically including load tests, temperature, Ohmic readings and voltage and made available as part of any warranty claim.
  • User agrees to make accessible the batteries under warranty to Power-Sonic or its authorized representative for inspection at reasonable hours and time intervals.
  • The warranty shall be voided if the battery becomes unserviceable due to fire, freezing, misuse, abuse, neglect physical damage or any act of nature.
  • The battery will be determined to be defective if it fails to deliver less than 60% of its rated capacity during the warranty period. The determination of actual capacity shall be made in accordance with the IEEE Std 1188 performance test guidelines.
  • Installation of the batteries must be performed by suitably qualified technicians and in accordance with proven acceptable practices.
  • This warranty shall apply only to original purchasers. It is not transferrable.
  • The replacement battery warranty will be of a length that matches the balance of the original warranty of the failed unit.


  • Contact the original point of purchase for instructions.
  • Request return authorization. No returns will be credited without an authorization.
  • In the case of returned products, the batteries must be packed with enough padding and in the appropriate cartons to eliminate the risk of damage in transit.

  • All defective batteries returned to Sealed Performance Batteries will become the property of Sealed Performance Batteries.
