When buying a car battery, you may have come across the terms prorated warranty and non-prorated.
Let's take a look at what these two terms mean. A non-prorated warranty protects any battery defects, and you will be getting a free replacement if you have issues. With a non-prorated warranty, you get full protection. You don't have to pay for the cost of the repair or replacement.
With a prorated warranty, you will have to pay for some of the cost of the replacement battery. What this means is that the battery manufacturer will cover part of the defective battery cost.
Manufacturers will divide a warranty into a non-prorated and prorated term.
Some car batteries may start with a non-prorated warranty for the first 1, 2, 3 or 5 years; this is referred to as the free replacement period. If your battery fails during this time, you should get a free replacement battery. After that, the battery warranty switches to prorated. If your car battery goes dead and no longer holds a charge, you will only be partially reimbursed.
Let's say you buy a battery that has a 6-year warranty. First, two years have a free replacement after that it is prorated. After the free replacement warranty (non-prorated) is up, you are now on the prorated period.
If your battery fails during:
Year 3 - You will bet only refunded 75 % of the battery value.
Year 4 - You will be refunded 50% of the battery value.
Year 5 - You will be refunded 25% of the battery value.
Year 6 - After year 6 you get refunded 0%.
Limited battery warranty means it will cover only certain circumstances and for a limited amount of time. The whole battery industry is going away from prorated battery warranties. Now you will find a 1, 2,3,4 years for free replacement and then no warranty (prorated) after that.
