Autozone Battery Hold Down (2025)

FAQs

Is a car battery hold down necessary? ›

Battery Safety

A moving battery could get damaged from friction and hitting other parts. In some cases, it could even start a fire if the terminals make contact with a piece of exposed metal. Battery hold downs keep the battery snug and in place, preventing these scenarios.

Maybe you have a different name for it — base clamp, brace, “that thing that keeps my battery secure.” Whatever you call it, the battery hold-down keeps your battery from moving as your car goes up and down hills, around corners and through quick starts and panic stops.

Hit a pothole or go over some rough railroad tracks and an unsecured battery can literally bounce into the air and hit the underside of your hood or the inside of a fender. It only takes a very brief contact with those terminals for significant and expensive damage to occur.

Plus, all of AutoZone's batteries, including Toyota Camry batteries and Honda Civic batteries, are backed by a 2-Year Free Replacement Warranty. Batteries from AutoZone are available for convenient online ordering and Same-Day Store Pick-up so you can replace your battery immediately.

A lot can depend on what condition your car battery is in. If you know your car battery is relatively new and has been kept in good condition, it can probably sit unused for about two weeks before it goes flat, however in other cases a car battery can last between two weeks to four months.

Your battery could be 75% charged or 100% charged and still be at death's door, the same way a cracked glass can be full of water. A fully charged battery could also be so aged, so sulfated and so weak that it can only hold a little bit of power for a brief period of time.

Its purpose is straightforward: to keep objects in place while you execute another action on them. Whether you work in a tiny cabinet shop or an industrial machine shop, you must constantly keep your components securely in place.

In other words, a holddown keeps a router from receiving route updates until the network appears to be stable—until either an interface stops changing state (flapping) or a better route is learned. Holddowns are usually implemented with timers. If the router detects that a network is unreachable, the timer is started.

Vehicle operation with loose or missing hold downs may allow battery vibration and leakage of electrolyte through vents. b) Battery abuse can also lead to overheating [2-6]. When batteries are overcharged, heat is generated, hydrogen gas is released, and electrolyte levels are reduced.

Those small points of contact often end up becoming super-heated by the electrical current and melt out. An even more dangerous and potentially catastrophic situation is possible if the terminals of an unsecured battery both come in contact with a metal surface, like the underside of the hood of a vehicle.

How long can a car sit without being driven before battery dies? ›

How long does a sitting car battery last? A car battery can last about four weeks to two months before it dies. Your car battery can only last so long before it fails when you're not driving because of key-off drain.

Typically, your car can sit about four weeks to two months without driving before the battery dies. The reason your car can sit only for so long before it dies is the fact that your car battery is in use even when you're not behind the wheel.

Will AutoZone replace your battery? Yes! Go to the closest AutoZone store near you to get your battery tested for free. If the report shows that you have a bad battery, we'll help you find a new one.

If you don't have a charger, the experts at AutoZone can assist you in selecting one. If you prefer not to work under the hood, you can bring your dead battery to an AutoZone store, where they will test and recharge it free of charge.

Battery Limited Warranty

If a battery is found defective after the free replacement period but before the end of the warranty period on your receipt, a credit towards the purchase of a new battery shall be made upon its return to any AutoZone store.

Ensure the Battery Is Secure and Properly Seated

A loose battery can cause vibrations that lead to internal damage and reduced lifespan. Make sure your battery is securely fastened in its tray. Check the brackets and clamps holding the battery in place.

Your battery will likely become flat if you've not been behind the wheel for more than two weeks or a month. It can't recharge without the alternator and can only retain the voltage for so long.

Safely store the batteries upright

Preventing the electrolyte from leaking is key, and so is eliminating the chance of arcing across posts. Not only should the batteries be stored upright, but there should be no opportunity for them to fall over.

There's just no getting around that fact, so if someone asks if a car battery can go dead just from sitting, the answer is a definitive "yes." The reason this happens is because all car batteries self-discharge over time.
