08 Prius Dead. 12 v battery and spare tire under Ice

Your dealer cost seems really cheap for install and all. Any way to charge the battery and get it to the dealer?

If not, posted below is the YouTube video that I followed...it is slow and pedantic, but it really shows you how to do it....and I had no idea what I was doing.

If you want to read about my adventure -- and it includes lots of other tips on how to know if it is the battery and lots of extra inside tips on how to replace the battery, here is the thread I started when my car was acting up:

if all you have is the trickle charger, you can try it to see if it helps; perhaps it will get the battery up just enough to get it going so you can get a new battery. otherwise, you'll need a mechanically inclined friend.

 

the ice won't hurt the battery, just hook it up and wait a few hours to see if it helps

 

shovlhed probably knows a lot more about this than I do.....so.....and this advice is worth just what you paid for it -- ZERO -- but, I would be worried about messing with water and electrical, and that is what ice is -- water.

If, by any strange quirk, some sort of "electrical haywire event" took place, I would think -- and I may be wrong -- that you could fry all the electronics in the car.

Not sure if it would be safe, but I would probably try something like a hairdryer to loosen the icy hold on the battery and then entirely take it out of the prius and charge it somewhere else.....just me....you might want to start a new post on this....most people on here are tired of 12V battery posts and might not look at one unless you have something unique like froze in ice battery to catch their interest

Looks like you are already hooked up....if it seems to be working....???? whom am I to say "nay."

 

Water is not a problem from a safety point of view with a 12 volt battery. The mains supply to the charger is another matter, and caution should be used there.
Any 12 volt battery can be used to jump start the car, lawn mower, snowmobile, snow blower, even a golf cart as long as you make sure to connect + to + and - to - with no mistakes. Even the cheapest of cheap jump cables will do as the Prius does not use the 12 volt to turn the engine.
Another replacement (direct fit) battery is the Exide FP-AGM51JIS this has a higher capacity and a longer guarantee (4 years) than the Optima.

You have to connect the charger to the house electrical supply, and it is that supply that requires caution with water around. The output of the charger "12 volts" is not a danger.
If you are struggling with the battery negative terminal follow the wire to where it is fastened to the car body just below the rear light and undo that bolt. removing the battery with the wire still attached. Most find this easier. Fit the wire to the new battery before fitting in place. Then re attach to the body.

It does not need to come from Toyota. Exide in the US would be my choice. The Optima is getting a poor reputation of late, but price and availability are factors. Living the other side of the Atlantic makes it difficult to guide you on purchasing.

If it is the original order a new one. Five years is a reasonable life seven years is very good. Being discharged and frozen will have done it no good at all.

no disrespect meant, but exide used to suck. (not as bad as hoppecke, they explode) interstate was better, but I don't know if they make 1 for the gen2. the dealer battery is good too.

ice doesn't matter at 12v at all.

 

my daughters '08 just died after 4 days at the airport. they jumped it and she's home, but i advised her to get a new battery. if your battery is 6 volts, that's a very bad sign.
