The warranty period begins from the date of shipment from Portable Power Systems. Examine your product thoroughly for damage before installation. If damage has occurred, immediately notify the shipping carrier and Portable Power Systems before placing the product into service. If possible, reject the product with the carrier at time of delivery or have the driver note damage on the official carrier record.

Portable Power Systems honors and administers the manufacturers warranty for all products that are sold in the manufacturers configuration, i.e. individual batteries and chargers. The warranty period is typically 12 months. Product with a longer/shorter warranty period will be specified on the website and/or with the product documentation. If multiple batteries are used in a system, the warranty only covers the defective battery. Proprietary products manufactured and sold as a Portable Power Systems item carry a one year warranty against defects in material and workmanship unless explicitly noted with the product description/details on this website or included documentation shipped with the product.

The customer is responsible for return shipping of any defective product. Portable Power Systems will ship the replacement product via Ground carrier. Under the warranty period our obligation will be limited to the repair or replacement of defective product. Such repair or replacement will be made only after our examination determines that said product is defective in material and/or workmanship. This warranty is void if the product has been repaired or altered in any way as to affect its use and/or operation as determined by Portable Power Systems. The warranty is also void if the product has been subject to, though not limited to, abuse, misuse, negligence, insufficient charging, over charging, improper storage or physical damage.

Battery life is based on the number of discharge/recharge cycles and the depth of discharges, not on age. A worn out battery from repeated cycles is normal wear and tear and not covered in the warranty.

If you suspect your product fails under warranty, please contact us to obtain a Return Material Authorization (RMA) number.  Returned products will undergo testing to determine the cause of the defect.  Should the battery fail due to a manufacturing defect, we will ship a replacement battery at no additional charge.
