Suggested reads about Car Battery Replacement

What do Car Battery Replacement services include?

Car battery replacement services usually include several steps. First, your car is towed to the garage. Mechanics then remove the old, damaged or non-working car battery. They then install the new car battery. If you haven’t bought the new battery yet, most hired mechanics or specialists can make the purchase for you, if their garage doesn’t have the right battery for your car in stock.

Note that this service is for replacing batteries of conventional engines instead of electric cars. This service also does not imply replacing the batteries in car key fobs.

Towing or transporting your car

Since you won’t be able to start your car, you’ll need a way to transport your car to the garage to get serviced. Some mechanics may offer a towing or transport service to get your car to their garage. Mechanics can attach your car to a tow truck, or place it on a flatbed truck. Your chosen mechanic should be able to tow or transport your car without damaging it.

Replacement service: removing the dead car battery

Your mechanic removes the old battery from your car, regardless of its make, model, and brand. Whether it is a Nissan, Ford, Mazda, BMW, Volvo or other car brands, they can remove the old battery. Mechanics disconnect the terminals to ensure their safe removal. The old battery is placed on a stack of old newspapers or cloth to catch any leaking liquids. Mechanics use safety gloves, and a mask and goggles as batteries contain dangerous substances like acid.  

New battery installation

Mechanics can put in your new battery while following best practices. Once the old battery is removed, they clean the battery terminals and clamps to prevent grounding, decreased conductivity or other issues. The mechanic uses a wire brush, baking soda and water to clean out the terminals and clamps, removing dirt, corrosion, or residue. After installing the new battery, the mechanic tests it by starting up your car, activating the wipers, radio, or other electronic accessories.

Old battery disposal

This is another service that your mechanic can do for you, as you cannot toss old car batteries in the rubbish bin. Old batteries have dangerous chemicals that pose a serious health hazard. The mechanic can take your old battery to a recycling centre or treatment facility. Be sure to list this as part of your service, unless you already have a recycling centre or garage in mind to take the old battery.

Car battery purchase

If you don’t have a replacement battery ready and the garage doesn’t stock the right one, some mechanics may offer this service for a small fee. Be sure to provide the mechanic with the money to buy the new car battery for you. Your mechanic can go to the shop, get the right battery then return to the garage to install the new battery straight away.

Auto Electrician to install new spotties, light bar, aux battery

$750

Seaforth, New South Wales

8th Jul 2025

I’ve got a 2004 Toyota Prado 120 Series that’s already pre-wired for roof and bumper lights, with Anderson plugs + power board etc run to the rear. All new hardware is on-site; I just need an auto-electrician to: 1. Mount & connect a new 40-inch LED light bar to my Rhino-Rack Pioneer 6 platform. Old bar is already removed; relay/switch/loom are in place – just bolt up and plug in. 2. Replace two bull-bar spot/driving lights with new LEDs. Existing harnesses/relays already fitted – straight swap. 3. Re-shuffle the batteries: Move the current auxiliary battery into the starter position, and install a new 120 Ah AGM/LiFePO₄ as the new auxiliary. 4. Swap the rear camp light on the telescopic pole for a new LED unit. Current wiring is already in place; simply fit the new light and reconnect. 5. Install new BCDC-style DC-DC charger between the two batteries with the correct fusing/circuit-breakers(will need to remove existing isolator in engine bay first). Rear Anderson plugs and power board are already wired – just integrate with the existing circuit. 6. Install a battery monitor (shunt-type) in a logical, easily viewed spot inside the cabin; run wiring/shunt at the battery end. 7. Test lights, charging, and cranking with me before you leave. Parts waiting in the garage: 1 × 40" single-row LED bar + brackets 2 × LED spot lights + brackets 1 × LED Camp light New 120 Ah battery + Heat shield (mounting plate already in engine bay) Battery monitor (head unit + shunt) Existing AGM battery (to become crank) BCDC + mounting plate You’ll need to bring: Any extra fuses/cables/lugs/loom for a professional finish Your own tools (crimpers, soldering iron, multimeter/test-light, etc.)

Collins is a great guy! Polite, knowledgeable and very easy to deal with. I'll definitely book him again for future work.

Hyandai i40 2013 issues (bought recently through private sale) - Reverse camera picture was not clear and is now totally cloudy - car alert sounds like seatbelt sound, indicator sounds are not working (they're showing on display though) - parking sensor sounds (front + back) not working I've found a cut cable under the driver's seat and in the boot the cables are on show there too, potentially they've been tampered with. Looking for investigation into issue and quotes on the cost to fix. Not really sure what budget is required for this job. Thanks
