REMEDY FOR BREACH OF WARRANTY
Subject to the exclusions and limitations set out above, if the Product fails
to comply with the Limited Warranty in clauses 1.2 or 1.3, BYD will repair or
replace the non-conforming Product or parts thereof within the warranty term
at no charge (or provide a partial refund) on the following conditions.
- Whether to repair or replace the Product will be determined by BYD at its sole discretion.
- The Product or any of its parts to be replaced will have the same performance and reliability as the original Product. If the production of the relevant type of the Product or any of its parts has been discontinued, withdrawn from the market, or otherwise unavailable, BYD may replace the Product or parts with a similar Product or part (which may include previously used parts that are equivalent to new in performance and reliability).
If BYD does not repair or replace the defective Product or parts, BYD will refund the Original Buyer an amount of money calculated as follows:
-
a) If the Product fails to comply with the Limited Performance Warranty in clause 1.3, BYD may calculate the refund using one of the two refund formulas below:
- Refund = maximum claim amount* x (warranted Minimum Throughput Energy -output energy of the Product recorded in the control module of the Product)/warranted Minimum Throughput Energy; or
- Refund = maximum claim amount* x (warranted remaining Usable Energy -remaining Usable Energy)/ warranted Usable Energy; and
-
b) If the Product cannot be operated, BYD will calculate the refund as follows:
-
Refund = (maximum claim amount*/60) x (60 – number of months since Warranty Start Date).
The maximum claim amount is the market value of the Product (or an equivalent Product) determined by BYD if it were purchased new and free of defects. -
The remedies as set out above are the sole and exclusive obligations of BYD to the Original
BYD Battery-Box LV Flex Lite Limited Warranty -Residential-South East Asia -EN V1.0
Buyer under this Limited Warranty and BYD will have no other liability to Original Buyer if the Product fails to comply with the Limited Warranty.
