How much does a Car Battery Replacement cost?

Typically, car battery replacement cost ranges between $150 - $300, including installation cost. The price varies on the size of the battery – commonly the larger the engine, the larger and more expensive the battery. German vehicles commonly have larger batteries or batteries installed under the seat and the cost can go up to $600. Truck batteries are generally more expensive as well.

How do Car Batteries work?

The car battery is what the car uses as a source of electrical power transmitted to the entire car and all of the electrical components (e.g. the starter motor, alternator, lights, radio, etc.). None of the electrical components in the car will function and the car will not start if the car's battery is not sufficiently charged or contains no charge at all. If your battery appears to have lost its charge, a good way to test it or recharge it is to conduct a battery boost.

When to replace your Car Battery?

  • Your car doesn’t start. A new battery has a definite capacity to provide power. This capacity is referred to as the cranking amps rating of the battery. The actual amps that a battery can supply become lower than its original rating as a battery ages. Once the cranking amps fall below a critical threshold, it will be hard or impossible to start your car.
  • Battery or charging system warning light is illuminated. A mechanic must perform a few basic tests to pinpoint if a battery replacement is necessary when a battery or charging system warning light illuminate.
  • Electrical components don’t work. Vehicle electrical components such as the security system can malfunction once a battery has started to fail, and the voltage produced by the battery drops. If you are experiencing electrical malfunctions, it’s a smart idea to have the battery tested.

How to change a Car Battery?

  • A temporary power source might be installed to avoid the possibility of losing radio presets or stored data in the PCM while the battery is out. When the battery is already completely unusable, this step is not needed.
  • The vehicle’s negative cable is detached from the battery, followed by the positive cable. The battery tie down system is loosened and the old battery will be taken out.
  • Cable ends and wiring are carefully examined to ensure no corrosion and cleanliness. Corrosion can be extreme and cable replacement or wiring repair is necessary in some cases.
  • The new battery is installed and the tie down system is reinstalled. Anti-corrosion compound is applied to the battery terminals. The positive terminal is reconnected followed by the negative terminal.
  • Some vehicles, like some models of BMW, VW, and Audi, may need PCM programming to input battery parameters. This step, achieved using a specialized scan tool, is essential to maximize battery life and avoid electrical system malfunctions.
  • The car is started and charging system output is measured and compared against the factory OEM specification to guarantee that the new battery will properly recharge. In general, charging output will be in the range of 13.8 to 14.8 volts but the exact specifications depend by built and model.

Is it safe to drive with a battery problem?

Yes, however, if you have a weak battery you might be left stranded somewhere if the battery dies completely and you cannot start your car. A faulty battery may also unnecessarily overload the alternator and could badly affect the operation of the vehicle’s electrical system, including the vehicle security system and the shift interlock.

Awesome experience. Had a mek in to replace a battery and change the oil in my car + a service package. Zero effort, done at home.

My wife’s car would start but stall at traffic lights. My best guess after checking battery and belts was that I’d require a new alternator. For the cost of a tow, the instamek mechanic diagnosed problem and got the car running. The technician Jack found a faulty sensor, cleaned the contacts and my wife is now happy once more. Very courteous and thorough service. No doubt I’ll be using them in the future.read more

I woke up and my car battery was dead at 10 am on a Saturday. I called my insurance who reccomended a tow truck and AMA who put me on a 45 minute waiting list. InstaMek answered my call right away and within 10 minutes we had an appointment scheduled for between 130-230 to get my battery replaced. The tech arrived at 239 I believe and I was up in my apartment with everything handled by 259. Came and replaced my battery at the back ally of my apartment and I was on the road by 3. AMA didn’t even call me back until 430. Very thankful for this service!read more

When the battery in my car died I called Instamek and they had a mechanic at my house the same day to replace my battery. Todd was fantastic! All in it was $266 which actually saved me money as I would have had to have my car towed to a shop. I will be using Instamek again!
