where to buy car battery acid

You generally don't need to buy new battery acid for a modern car battery. Most car batteries sold today are maintenance-free, meaning they are sealed and designed for their entire lifespan without requiring you to add fluid. If your battery level is low, the correct fluid to add is distilled water, not acid. However, if you are specifically working on refilling a serviceable, old-style battery, you can find battery electrolyte, which is a diluted sulfuric acid solution, at some auto parts stores.

The primary and safest source is a dedicated automotive retailer. Stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts often carry battery acid in pre-mixed containers. It's typically found in the battery section. You can also check with tractor supply stores or specialized battery shops. It is crucial to handle battery acid with extreme care. Always wear personal protective equipment (PPE) including acid-resistant gloves and safety goggles. The table below lists common retail options and key considerations.

Advance Auto PartsVaries by locationPre-mixed liquidStaff can often provide handling guidance.
O'Reilly Auto PartsVaries by locationPre-mixed liquidStored with other battery maintenance fluids.
NAPA Auto PartsLess commonPre-mixed liquidCall ahead to confirm local store inventory.

Independent Battery ShopsHigh likelihoodPre-mixed or concentrateExperts in battery servicing and safety.

Before you attempt to add any fluid, confirm your battery is the serviceable type by looking for removable caps on top. Adding acid to a battery that only needs water, or to a maintenance-free battery, can permanently damage it and is dangerous. If your battery is consistently low on fluid, it may be a sign of overcharging and you should have your vehicle's charging system checked by a professional.

Honestly, just go to an auto parts store. I had to get some for an old lawn tractor battery last summer. I walked into AutoZone, asked the guy at the counter, and he had it right there. He also handed me a pair of gloves, which was smart because that stuff is no joke. They'll usually make you sign a quick paper since it's hazardous. Definitely call your local store first to save a trip, but that's your best bet.

Focus on safety above all else. Battery electrolyte is a corrosive acid that can cause severe burns. If you must handle it, purchase from a reputable automotive supplier. Wear full protective gear: heavy gloves and safety glasses are non-negotiable. Have baking soda and water nearby to neutralize any accidental spills immediately. This is not a product for casual experimentation. Proper disposal of the empty container is also a critical step.

Can the car run the air conditioner while idling?

Yes, the car can run the air conditioner while idling. However, it is not advisable to keep the air conditioner on for too long during idling, as it may have the following effects: 1. Increased fuel consumption: The car already consumes fuel while idling, and the operation of the air conditioner's compressor requires the engine to drive it, which will undoubtedly increase fuel consumption. 2. Shortened battery life: The air conditioner's blower is powered by the battery. When the car is idling, the battery's charging efficiency is relatively low, and the operation of the blower may lead to battery discharge. Prolonged battery discharge can shorten the battery's lifespan.
