I need to boost my 12v battery on my 2002 prius

I need to boost my 12 volt battery on my 2002 prius but i'm not able to get access to the battery. the cover that is over the battery wont come off. It has a pivot point at the top and a plug on the forward part of the cover, it also has what appears to be a screw on the rear portion of the cover. I can get the plug off but i'm not able to get the screw out. It just keeps turning when i turn it but it doesn't seem to loosen at all.

Is there a trick to getting the screw to catch and unscrew. or is it really a plug and i should just yank it out. (i'm not the first owner)

The bolt screws into a nut. this nut is probably spinning in its housing. While trying to unscrew bolt pull up on cover to lock in nut. You might need an extra hand in doing this. USE enough force that will help lock the nut against housing but DO NOT overdo it and crack cover.

FYI there are other options which I am not keen using. your auto store sells the cigarette lighter booster cable. I am not fond of this idea due to the length of cable involved but it will help. Just let the cars sit for about 10 minutes while both are plugged in and you should be ok.

12 volt 6 amps to quickly charge it from dead/flat or very low.

12 volt 2 amps as a trickle charge to maintain the battery when you are not using the vehicle for an extended time.

I have 2006 Toyota Prius. The battery is dead and I am not able to access the battery in the trunk as trunk can not be opened.

Under the hood there's a 12 volt battery access terminal you can connect jumper cables to. Otherwise, you'd have to fold down the rear seats and dig around in the back to get at the battery. Toyota was kind enough to think ahead for such an eventuality. By the way - it's in your owner's manual somewhere.

2002 toyota prius

Hello, the first thing I would recommend that you buy a repair manual that shows step by step instructions, with illustrations I can't do that here. You'll need some common metric tools and a voltmeter, there are high voltages involved and you will need to wear insulated gloves rated at least to 1000 volts DC to prevent severe injury or possibly death.

The actual replacement is not that difficult:
Disconnect the 12 volt auxiliary battery
disconnect the orange service plug on the hybrid battery and tape the connector on the battery
remove the rear seat and the seat back braces
remove the trunk carpet and the spare tire cover
remove the two orange cables going to the front
measure dc voltage at the terminals where the cables were removed there must be less than 1 volt.
remove the 12 mm bolts that connect the battery to the body including the torx bolt
slide the battery back and have someone help to lift it out.

2005 Toyota Prius. Red Brake and yellow ABS and VSC warnings are continuously on.Dealer told me to replace 12 volt battery power supply. Done that but no resolve.Anything I else I can check??

One or more ABS sensors or ride-height sensors could be bad. You need specialized dealer-only scanner to read codes to determine actual problem if new 12 volt battery didn't solve it.

Brand new Prius won't start. Battery appears to be dead. What do I do???

The Prius has a small 12 volt battery for starting the computer. It is easily discharged if something is left on or a door is left open. Your owners manual will show you where to charge or jump the car from under the hood in the fuse box. Or you can access the battery in the right rear trunk area.
