Warranty

WARRANTY FOR ALL COMBA PARTS EXCLUDING LITHIUM ION PHOSPHATE BATTERIES

Comba manufactures products which are inspected and submitted to final test before shipment. If, within the warranty period, any defect is discovered in whole or part of the products with respect to material or workmanship and which should reasonably have been expected to be within Comba’s control, Comba will at its own option make good the defect in either of the two following ways:

 

  • Comba will, without charge, carry out such repair at its own facilities provided that notice has been given by the Purchaser promptly after the defect is discovered and that the products in whole or part have been forwarded, without delay to Comba’s warehouse in Milpitas, CA. Labor costs for disassembly and reassembly in the Purchaser’s site in whole or in part, will be borne by the Purchaser. After repair the products will, in whole or in part, be returned to the Purchaser’s headquarters or manned regional office. Comba accepts no responsibility for any defects caused in connection with the assembly work at the Purchaser’s site.
  • Comba will send free replacement for the defective part to the Purchaser’s headquarters or manned regional office. Labor costs for disassembly and reassembly at site shall be borne by the Purchaser.  Comba takes no responsibility for defects in connection with the replacement work at the Purchaser’s site.

 

 

A new warranty period shall apply, under the same terms and conditions as those applicable to the original parts, for those parts supplied or repaired in accordance with these warranty conditions, although no longer than three (3) months after the end of the original warranty period. Defective parts replaced in accordance with these warranty conditions shall be placed at Comba’s disposal at site and shall upon request be returned to Comba’s warehouse in Milpitas, CA or agreed upon location.

This warranty does not apply to defects caused by normal wear and tear, abnormal conditions of working, accidental damage, improper handling, or neglect of instructions, given by Comba. It does not cover defects caused by faulty maintenance or from alterations or repair carried out without Comba’s authorization. The warranty does not include consumable parts in the products.

The warranty period is thirty-six (36) months from the date of delivery from Comba. The warranty period for repaired parts, repaired after the original warranty period has expired, is three (3) months.

 

WARRANTY SPECIFICALLY FOR COMBA LITHIUM ION PHOSPHATE BATTERIES

 

 

Warranty period

Comba Telecom warrants the Lithium Iron Phosphate (LiFePO4) batteries that are utilized in the Comba Version 2 and Version 3 Battery Backup Units for 5 years (60 months). The warranty period commences upon date of shipment from Comba Telecom.

For the first two years (24 months) of the warranty period, the battery will be replaced at no cost. For the period of time from month 25 (beginning of year 3) through the end of the five year (60 month) warranty period, the replacement battery will have a replacement cost that is pro-rated based on the amount of time the battery was in use, prior to failure.

 

 

 

 

 

Terms and conditions of warranty

If the battery fails within the 2 years (24 month) Free Replacement period (commences upon ship date) for failure to perform due to defects in materials or workmanship, Comba Telecom will provide a new replacement battery of the same type at no charge except for shipping costs. In this case, the replacement battery will carry the remaining balance (3 years/36 months) of the original 5 year warranty.

If the battery fails after the 2 year (24 month) Free Replacement period, but prior to the termination of the 5 year (60 month) warranty period, for failure to perform due to defects in materials or workmanship, Comba will provide a replacement battery of the same type at a discounted replacement cost (plus shipping costs) per the replacement cost table at the end of this document. In these cases, the replacement battery will have a new full 5 year (60 month) warranty.

The warranty on the replacement battery will be in effect only if the battery is replaced by a certified/authorized Comba System Integrator. The System Integrator may charge the end user a fee for replacement of the battery.
