AutoZone sells car battery chargers, not electric vehicle chargers

AutoZone carries 12-volt battery chargers for traditional gasoline and diesel vehicles. These devices restore charge to a car's lead-acid battery when it has drained. They are not chargers for plug-in hybrid or fully electric vehicles — those require different equipment designed for high-voltage systems.

AutoZone's charger lineup includes trickle chargers (slow, overnight charging), standard chargers (faster, a few hours), and jump starters with charging capability. Prices and models change by location and season, so checking your local AutoZone store or their website shows what is currently in stock.

If you own a traditional car and your battery has gone dead or weak, a charger from AutoZone can restore it without a tow truck. If you own an electric vehicle, you will need a different type of charger — one designed for EV charging — which AutoZone does not stock.

Key Takeaways

  • AutoZone chargers work only on 12-volt lead-acid batteries found in gasoline and diesel cars, not on electric vehicle batteries.
  • Trickle chargers charge slowly overnight and cost less; standard chargers work faster but require more supervision.
  • Jump starters with charging capability let you start a dead battery and then charge it, all in one device.
  • Electric vehicle owners need dedicated EV charging equipment, which is sold at different retailers and often requires professional installation.

Types of chargers AutoZone carries

AutoZone stocks three main categories. Trickle chargers deliver a small, steady current over many hours or overnight. They are gentler on older batteries and cost between $30 and $80. A trickle charger is useful if you are storing a vehicle for the winter or have a battery that holds charge poorly.

Standard battery chargers deliver more current and can restore a dead battery in two to six hours. They typically cost $50 to $150 and require you to monitor them — you cannot leave them unattended as long as a trickle charger. Most people use a standard charger when they need their car back in service the same day.

Jump starters with charging capability are portable boxes that can jump-start a dead battery when ready and also charge it over time. They range from $100 to $300 and are useful if you do not have access to a wall outlet or another vehicle to jump from. Some include USB ports to charge phones and other devices.

How to choose the right charger for your situation

If your car battery dies once or twice a year and you have time to wait, a trickle charger is the cheapest option. If your battery is aging and you want to keep it in good condition during storage, a trickle charger also prevents the slow drain that happens when a car sits unused.

If you need your car running within a few hours and you have access to a wall outlet, a standard charger is faster and more practical. If you are frequently on the road, work in a location without reliable power, or want a backup for emergencies, a portable jump starter with charging capability gives you the most flexibility.

Check the charger's output in amps — higher amperage charges faster but can stress an older battery. Most AutoZone chargers list the amp rating on the box. If your vehicle manual specifies a maximum charging rate, match or stay below it.

What chargers cannot do

A battery charger restores charge to a battery that is temporarily drained, but it cannot fix a battery that is permanently damaged. If your battery is more than three to five years old, fails to hold charge even after a full charge cycle, or shows physical damage like cracks or leaks, the battery itself needs replacement, not charging.

Chargers also cannot diagnose why your battery drained in the first place. A battery that dies repeatedly may signal a problem with your alternator, starter, or electrical system. Charging it will get you back on the road, but you should have the underlying issue inspected by a mechanic.

If you own an electric vehicle, a 12-volt charger will not charge the main battery pack. Electric vehicles have a separate 12-volt battery for accessories, but the main propulsion battery requires a dedicated EV charger — a different product entirely.

Where to buy and what to expect

AutoZone stores are located in most U.S. towns and cities. You can walk in, see chargers in person, and ask staff about which model fits your needs. Many AutoZone locations also allow you to return chargers within a set period if they do not work for your situation.

AutoZone's website shows inventory at your nearest store and allows online ordering for in-store pickup. Shipping to your home is also available but may take several days. Prices vary slightly by location and current promotions.

Other retailers like Walmart, Amazon, and Advance Auto Parts also carry 12-volt chargers. Comparing prices and reviews across retailers can help you find the model that best matches your budget and needs.

Safety basics when using a charger

Always read the charger's manual before use. Connect the red clamp to the positive terminal (marked +) on your battery and the black clamp to the negative terminal (marked −). Never reverse the clamps — this can damage the charger and the vehicle's electrical system.

Charge in a well-ventilated space. Batteries release hydrogen gas during charging, which is flammable. Do not charge in a closed garage or enclosed space. Keep the charger away from water and do not touch the clamps while the charger is running.

If your battery is cracked, leaking, or visibly damaged, do not attempt to charge it. A damaged battery can overheat or rupture. Have it replaced instead.

Frequently Asked Questions

Can I use an AutoZone charger on a car battery that is completely dead?

Yes. A completely dead battery can still be charged. Connect the charger and let it run — a standard charger may take several hours, while a trickle charger takes overnight. If the battery does not accept a charge after 24 hours, the battery itself may be damaged and need replacement.

Will a charger work on a battery in a car that is turned off?

Yes. The charger connects directly to the battery terminals, not to the car's ignition. The car can be off, and the charger will still restore the battery's charge. Make sure the car is parked safely and the engine is off before you begin.

How long does it take to charge a dead car battery?

A trickle charger takes 12 to 24 hours. A standard charger takes 2 to 6 hours depending on how dead the battery is and the charger's amperage. A portable jump starter can provide enough charge to start the engine in minutes, though a full charge takes longer.

Can I leave a charger connected overnight?

Trickle chargers are designed for overnight use and will not overcharge. Standard chargers should not be left unattended for long periods — most have an automatic shutoff, but check your manual. Portable jump starters should be disconnected once the battery is charged.

What is the difference between a charger and a jump starter?

A charger restores battery charge over time. A jump starter provides an when ready boost of power to start the engine when ready, then may also charge the battery. Jump starters are faster for emergencies but chargers are better for a full restoration of battery health.
