A car battery warranty in the UAE commonly lasts between one and two years and comes in one of two forms: free replacement, where a faulty battery is swapped at no cost, or pro-rata, where you get a discount on a new battery that shrinks as the old one ages. Either way, a claim is approved only after the battery is tested and found to have a manufacturing fault, not a fault caused by the car, the fitting or the way it was used.
That makes the warranty one of the most useful things to compare when you are choosing between quotes. Two batteries with the same price and the same months of cover can give you very different protection once you read the terms. This guide explains what those terms mean, what tends to void them, and what to keep so a claim goes smoothly.
Free replacement vs pro-rata warranty
Free-replacement period
During a free-replacement period, a battery that fails a proper test is replaced with a new one at no charge. This is the simplest kind of cover and the most valuable. In a hot climate, where many batteries fail suddenly rather than slowly, it is the part of the warranty you are most likely to use.
Pro-rata period
A pro-rata period follows the free-replacement period, or sometimes replaces it entirely. If the battery fails during this time, you do not get a free battery. Instead, you get a discount on a new one based on how much of the warranty period was left. A battery that fails early in a pro-rata period earns a bigger discount than one that fails near the end.
Some manufacturers print both periods on the battery label, for example a number of months of free replacement followed by a number of months of pro-rata cover. A headline figure that combines the two can make a warranty sound longer than it really is.
How the two compare
| Warranty type | What you get if the battery fails | What to check |
|---|---|---|
| Free replacement | A new battery at no cost | How many months, and from which date |
| Pro-rata | A discount on a new battery that shrinks with age | How the discount is calculated |
| Mixed | Free replacement first, then pro-rata | How many months of each, not just the total |
| “Warranty available” with no details | Unclear | Ask for the period and type in writing |
When you compare quotes, compare the free-replacement months first. Twenty-four months of mixed cover with only a short free period can be worth less than a straight free-replacement warranty that sounds shorter.
Which date the warranty starts from
Warranties usually run from the date of purchase or fitting, which is why the invoice matters so much. Some distributors date the warranty from fitment; Al Kharbash, the UAE distributor for Exide automotive batteries, for example, describes an 18-month warranty programme from the date of fitment. A battery that sat on a shelf for months before it was fitted has already aged, even if its warranty clock has not started, which is another reason to check the manufacturing date before you buy.
What voids a car battery warranty
Warranties cover manufacturing defects, such as a dead cell or an internal short. They do not cover failures caused by something outside the battery. The common exclusions are below.
Wrong fitment
A battery that is the wrong size, capacity or technology for the car is likely to fail early, and the warranty will not cover it. The most common example is a flooded battery fitted to a car that needs an AGM or EFB battery for its start-stop system. Our guide to AGM vs EFB vs flooded batteries explains how to tell which one your car needs.
On many German and European cars, a new battery also has to be registered with the car’s battery management system. If it is not, the car may charge it incorrectly, and an early failure can be traced back to the missed step. That is why German car battery replacement should include registration and coding where the car needs it.
Undercharging or overcharging
A faulty alternator, a slipping belt or a poor connection can leave a battery permanently undercharged, which slowly damages it. An alternator that charges at too high a voltage can cook a battery from the inside, often swelling the case. Both are charging-system faults rather than battery faults, so they are typically excluded. A short commute in heavy traffic with the AC on full can also keep a battery below full charge for long periods, which shortens its life without being a defect.
Deep discharge and parasitic drain
A battery left fully drained, for example while the car sits in a basement car park for weeks during a summer trip, can suffer sulphation that does not reverse. A constant drain from an aftermarket alarm, dashcam or faulty module has the same effect over time. Many warranty terms exclude damage from deep discharge.
Physical damage
A cracked case, a broken terminal, a battery that was dropped or one whose hold-down clamp was missing are all outside warranty. So is a battery that has been opened, topped up incorrectly or tampered with.
Commercial or heavy use
Some warranties are shorter, or do not apply at all, when the battery is used in a taxi, delivery vehicle or other commercial fleet, because the duty cycle is much harder. If you drive for work, ask before you buy.
Why manufacturers test before replacing
A dead battery is not always a faulty battery. Many batteries returned under warranty turn out to be healthy but flat, and a correct charge brings them back. Others have failed because of the car, not the battery. Testing separates the three cases.
A warranty test normally covers:
- Charge and resting voltage. A battery that is simply flat is charged before it is judged.
- Cranking capacity. A digital tester measures how much starting current the battery can still deliver against its rated CCA.
- Cell condition. A dead or shorted cell shows up as a voltage well below normal that does not recover with charging.
- The car’s charging system. If the alternator is charging too low or too high, the battery was a victim, and a new one would fail the same way.
This is also why a supplier may ask to charge and retest a battery before agreeing to replace it. It is not a delaying tactic. It protects you from paying for a battery you did not need, and it stops a charging fault from killing a second battery. A quick car battery test will show which of these situations you are in.
Keep the invoice and know the date code
Two pieces of information decide almost every claim.
The invoice or warranty card
The invoice should show the battery brand and model, the date of fitting, your car and the warranty period and type. Keep a photo of it on your phone. If the seller keeps a record against your phone number or plate, ask them to confirm it at the time of purchase. Without proof of purchase, a claim can be refused even when the battery is clearly faulty.
The manufacturing date code
Every legitimate battery carries a date code stamped or printed on the case or label, showing when it was made. The format differs by manufacturer, so it may be a printed date, a letter and number code, or a series of characters that the seller can decode. A battery with a missing or scratched-off date code is a warning sign, as we explain in our guide to the car battery price in Dubai.
The date code matters for two reasons. It shows whether the battery was fresh when fitted, and it helps a supplier confirm that the battery in your car is the one on your invoice.
Checking a brand warranty such as Amaron
Drivers often search for how to check an Amaron, Exide or ACDelco car battery warranty. In practice, the warranty on a battery bought in the UAE is honoured through the seller and the brand’s UAE distributor, not through a manufacturer’s website in another country. The terms printed on Indian or American product pages, for example, often differ from those that apply here. The reliable route is the warranty card or invoice from the seller, together with the battery’s serial number and date code. If the seller has closed or stopped trading, the brand’s UAE distributor is the next place to ask.
Typical UAE warranty lengths by brand
Warranty periods vary by brand, by battery range within a brand, and by seller, and very few distributors publish their terms in full. The table separates our advertised service warranty from supplier-dependent terms. Confirm the period, exclusions and claim process in writing for the exact battery before buying.
| Brand or seller | Warranty period | Type and source |
|---|---|---|
| Batteries fitted by Dubai Battery | Up to 24 months, depending on brand and type | Stated on your invoice; claims handled at your location |
| Exide and other UAE distributor programmes | Confirm for the exact product and seller | Use the warranty card, invoice and distributor’s current written terms |
Note that the Exide name is used by two unrelated manufacturers, one based in Europe and one in India, and both can appear on UAE shelves. The label shows which one you are buying, and the warranty terms can differ between them.
For other brands such as Amaron, ACDelco, Varta, Bosch and Solite, periods quoted online by retailers vary widely and often conflict, so we have not listed figures we could not confirm. Our technician will tell you the exact warranty on each battery available for your car before you agree.

How mobile services handle warranty claims on site
With a traditional battery shop, a warranty claim usually means getting the car there. If the battery is dead, that may mean a jump start or a tow before anyone looks at it.
A mobile battery service works the other way round. When you report a problem with a battery we fitted, the process is:
- Send the details on WhatsApp. Your name, phone number or plate, and a short description of what is happening.
- A technician comes to the car. At home, at the office or in the car park where the car stopped.
- The battery and charging system are tested on site. This shows whether the battery is faulty, flat, or the victim of an alternator or drain problem.
- The outcome is explained there and then. If the battery is faulty and within the terms, it is replaced on the spot. If it is flat but healthy, it is charged or jump started. If the cause is the car, you are told what needs fixing so a new battery is not wasted.
Because testing is free with any visit, there is no cost to finding out where you stand. If a replacement is needed outside warranty, the technician can fit a new battery during the same visit as part of our car battery replacement in Dubai service. We also cover Abu Dhabi and Sharjah.
Questions to ask before you buy
Before you agree to any battery quote, ask:
- How many months of warranty, and how many of those are free replacement?
- Does the warranty start from the date of fitting or the date of purchase?
- What does the warranty exclude?
- Do you come to me for a claim, or do I need to bring the car in?
- What is the manufacturing date of this battery?
- Will you test my alternator after fitting?
A seller who answers all six clearly, and writes the warranty on the invoice, is usually a seller who will honour it.
