How long does it take to charge a dead battery?
Determining Charge Time. The more discharged that your battery is, the longer it will take to recharge it. Batteries usually take several hours to recharge; if the battery is severely discharged (12.2 volts or less for an flooded battery) then it may take up to 12 hours or more to recharge.
AutoZone Starting & Charging guide - Batteries. AutoZone stores can charge your battery for free. We have a Duralast fast charger that can charge a 12 volt battery in about 30 minutes. AutoZone also offers overnight battery charging for 6 and 12 volt lawn and garden, motorcycle and marine batteries.
- All Autozone locations should offer the service. Please note that while Autozone says they offer check engine light diagnostics, it typically is not as thorough as people expect. The "diagnostic" consists of having error codes scanned and then possible causes and solutions being printed out.
- To return a product to an AutoZone store, return an item in its original condition and packaging, with receipt, within 90 days of the purchase date to request a refund. Return a defective item within the warranty period. Requests for refunds may be denied if the item has been used or installed.
- Place the new battery in the battery hold-down tray and secure the battery with the hold-down clamp. Spray both terminal ends with anti-corrosion solution. Attach and tighten the positive battery cable (Red). Attach and tighten the negative battery cable (Black).
Once you are familiar with the basics of your battery charger, you can now connect it to the vehicle's battery. You can charge the battery while it is still inside the car or if it has been removed, either method is fine. Next attach the negative (black) clamp to the negative post on the battery.
- A car battery usually holds 48 amps so if you take that it charges at approximately 1 amp per hour you can work out how long it will take to charge your battery with various amperage chargers. Charging your battery with a four amp charger will take about 12 hours to get a full charge out of this low amperage.
- Connect the positive cable (red)(+) to the positive post (+) of the dead battery. Connect the other end of the positive cable to the good battery. Connect the negative cable (black)(-) to the negative post of the good battery. Connect the negative cable to a metal part of the dead vehicles engine.
- Either the automatic gearbox prevents rolling the car at all or there is an open clutch which cannot be closed manually. So if you want to be prepared for your automatic car not starting because of a dead battery, put a jump start cable in your trunk and/or sign a membership with a road assistance organisation.
The cost of a car battery. According to CostHelper, a typical car battery costs between $50 and $120, while premium batteries cost $90 to $200. Service providers on Angie's List that we spoke with say the average battery cost runs in the $75 to $120 range. Several factors affect the cost, such as battery type.
- When the local auto parts store won't pay you cash, you can always take it to a scrap yard. You might think that scrap yards are only for selling old refrigerators and even recycling old glass jars and bottles. Used car batteries are purchased for their lead core that can be remanufactured and used again.
- If your vehicle's battery is dead, the service driver will jump-start your vehicle, if possible. If it cannot be started, towing will be provided under the towing benefit. AAA Battery Service is a mobile battery testing and replacement service. AAA Battery Service is only available in select areas, during select hours.
- The life expectancy for your car battery is typically between four to six years. Several factors determine how long your battery will last, for example weather conditions, vehicle type and driving habits. There are, however, several key pointers you can utilise to help increase the life expectancy of your car battery.
