BATTERY PRO-RATED 5 YEAR WARRANTY
Warranty period
Comba Telecom warrants the Lithium Iron Phosphate (LiFePO
4
) 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 2 years (24 months) of the warranty period, the battery will be replaced at no cost. For
the period from month 25 (beginning of year 3) through the end of the 5-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.
The Comba certified integrator will receive the replacement battery for installation in the Comba BBU; the
integrator will arrange for disposal of the defective battery.
