A genuine AGS battery comes with a real manufacturer warranty — but many customers lose out simply because they don't know how it works. Here's the plain-English version.

What the warranty usually covers

AGS batteries carry a warranty against manufacturing defects — typically issues present from the factory, such as:

• Internal short circuits
• Premature failure under normal use within the warranty period
• Manufacturing faults in the plates or casing

If the battery fails within the warranty period due to a defect, it is repaired or replaced (often on a pro-rata basis in later years).

What is NOT covered (and what voids the warranty)

Warranty does not cover damage caused by how the battery is used or maintained:

• Deep discharge / leaving it flat — the most common cause, and not covered.
• Overcharging — a faulty alternator or charger boiling the battery dry.
• Physical damage — cracks, bulging from heat, dropped or impact-damaged cases.
• Wrong application — using a small battery in a heavy vehicle.
• Neglect — running a conventional battery dry of water.
• No proof of purchase — the warranty is tied to the original invoice.

How to claim (keep it painless)

1. Keep the original invoice/receipt — it has the purchase date and is your proof. Without it, a claim is hard.
2. Bring the battery in to an Authorized AGS Dealer (like us) — don't throw it away.
3. We test it to confirm the failure mode.
4. If it's a covered defect, we process the warranty claim through AGS on your behalf.
5. You get a repair/replacement per the warranty terms.

Buy genuine to get a real warranty

Counterfeit or grey-market "AGS" batteries may look identical but carry no valid warranty — the serial number won't register with AGS. Only buy from an authorized dealer.
