The battery in my car is fucked and needs to be replaced. How easy is it to change it yourself? I haven't done much stuff on cars but I'm not afraid of DIY stuff.

The battery looks like it is very accessible and that all it takes is to unscrew a few bolts.

    Cars run on 12V DC, so you won't seriously hurt yourself even if you do it wrong. Unless it's a liquid electrolyte, and then try not to spill, although those are uncommon.

    Make sure you throw the old one in the sea to help the eels, tho

    Mostly not too bad. Look up how to do it on YouTube for your specific car though

      Wear gloves and disconnect and reconnect the terminals in the right order

    Some auto parts stores will install it for free, and usually give you some money back for your old battery (core deposit or something). Just make sure it's the right size and has enough amps - for instance if your car is a diesel it needs more.

    Big box store batteries are cheaper, but generally not as good. But it doesn't matter much, all car batteries work fine.

    Don't toss the old battery in the ocean, please.

    From my POV it's very easy. The battery needs to be recycled in almost every jurisdiction, bear in mind.

    I'd definitely wear gloves as well since the terminals, at least on ones I've seen, tend to have a build-up of corrosion for whatever reason.

    At some auto parts stores the employees will help you replace the battery. I wouldn't know without seeing your car, but if it looks easy it probably is. Just make sure the new one is fully secured.

    Easy peasy, if you've got wrenches. It'll probably be a 10mm bolt for however the battery is retained, and whatever it is for the battery terminal cables.

    If you're SOL and can't get a ride there, the hardest part is bringing the old batteryback/getting the new one to your car. Shit's usually pretty heavy.

    To add on to what's already been said, make sure to clean the connectors while you're at it, there should be no rust or dirt. The poles on new batteries should usually be scrubbed with a wire brush or steel wool before connecting it, to clean dirt or any corrosion

    it literally is just that. if you have the right size wrench it shouldn't take you more than 20 minutes. only tip is wear gloves for safety.

      I may be wrong but I believe when you put the new battery in, if you connect the negative first and the positive touches any metal part theres a chance of a short circuit, so you actually want to connect the positive first. The negative should never be on the battery unless the positive is connected. That's always been my reasoning anyway.

    It's very easy. You just take it disconnect it, take it, then put in and connect the new kne. You can usually take your car to an auto parts store and they can get you a new one, help you install it, and recycle it for you. Or if you can't drive/want to change it yourself you can still go in and they can look up what you need and recycle your old one.

    If the negative terminal is connected, then the positive terminal will short to any metal part of the car. Touch the engine with it, big sparks. Touch your wrench to a random bracket while you’re removing the positive, big sparks.

    Pretty much. The only other car thing I can do is change a tyre and a battery swap was about as easy. Take off the retention bolts, take the cables off the terminals, lift it out, and put the new one in its place with the process reversed. The only thing that gave me trouble is that it reset the car's computer and makes it underestimate fuel economy now.
