Prorated vs Non-Prorated Car Battery Warranty

If you are looking to buy a car battery, you may have come across the terms prorated warranty and non-prorated warranty.

Let's take a look at what these two terms mean. 


A non-prorated warranty protects against 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 non-prorated car battery warranty, should your car battery fail to hold a charge during the free replacement warranty period, your battery will be replaced for free. 


With a prorated warranty, you will have to pay for some of the replacement battery's cost.  What this means is that the battery manufacturer will cover part of the defective battery cost. 

If you have a prorated warranty, should your car battery fail during the warranty period, you will be reimbursed for the remaining portion of the warranty? Let say a prorated battery with a 5-year warranty fails in 2.5 years. You will be refunded only 50% of the purchase price. In some cases, the reimbursement can only be applied towards your next replacement battery. 

Non-prorated then Prorated 

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 dies and no longer holds a charge, you will only be partially reimbursed. 


prorated vs non pro rated car battery warrantyLet'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%. 

What does Battery Limited Warranty mean?

A limited battery warranty means it will cover only certain circumstances and 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.
