>take the battery out and charge it from a wall socket?
You would need a trickle charger to do that.

Just bum a jump start.

If the engine cranks, your battery is not the problem.

You obviously have charge.

Do you have fuel in your car?

Smell the exhaust after trying to start it, does it smell rich and petrolly?

Maybe a fuel pump is fucked, or your plugs are fouled, or anything else.

But your battery is not the problem.

A trickle charger is not a bad thing to have though.

sorry, maybe im not explaining correctly. it just makes this repeating clicking sound. I left my car air conditioner on for hours because im an idiot, and when i came back, the dash board did say "low voltage". so i think it is the battery?

i have a full tank.

>>15575062
yeah i might not even be able to get the battery out, and theres no outlet nearby.

ive never done this before so i have no idea what im doing. hoping my battery doesnt explode...

the battery is in the trunk but you can jump it from the red post under the hood too

the black circled thing is the positive terminal correct?

>>15575121
Yes. For the ground just attach it to somewhere on your chassis that's bare metal.

+(red) into +-terminal and -(black) into frame or block. Then start with aux power. If it doesn´t want to start again after some driving, then you might have broken battery. Measure, with a multi-meter, from terminal to terminal. If not around 12V-> you need a new battery.
Broke the battery from my motorcycle recently. Measured 9,6V from 12V battery, one section(or whatever it is called in english) was broken.

you're going to need a charger if you want to charge it from the wall. not a bad thing to have but kind of expensive.

call a friend, go pick up some jumper cables and jump start the engine. then drive it around for a while.
