    If I do not make sure my 2003 Prius gets driven every week, it is dead within two weeks. I have come back from several trips only to call AAA because my car will not start. It used last two to three weeks. It seems to be dying in less than two weeks now and most recently, just 5 days later it was dead again. What is going on? It is time to sell this thing for parts?

    Very likely just a bad 12V battery. 12V batter isn’t that expensive and it will get bad with age. So if you can’t remember when it was last changed, it’s probably time to replace it.

    That's a much better deal. The dealership here is saying $400 for the battery and $103 for labor which seems overpriced to me. They recommended I disconnect the battery before trips because the onboard computers will drain even a new battery within five days. That also seems a little off. I'm not so sure about this dealership.

    The actual battery shouldn't cost more than around $250, and a professional shouldn't take longer than 15 minutes or so to install it. Maybe add a few minutes to make sure it's working afterwards, but it sounds like they're charging you close to double for the part and an hour's worth of labor.

    Yeah, way too high at the stealership. My dealer sells the Toyota battery for just over $200, not a bad price. It's more like 45 minutes for the first-time DIYer, with the need to disconnect a few boxes at the battery and a piece of vent tubing, and get it back in place correctly.

    Many local shops and mobile places are trained for the Prius, and can offer a good price. My wife had to get AAA to do ours once on the road, basically free labor included with their mobile service.

    That kit that Jimbo linked to is the easiest solution--you pay extra for the convenience so it may be worth it. It's a great it!

    As far as getting it installed, it's just a basic shade tree mechanics task. Find a guy in your neighborhood and ask him or her to change your battery if you don't feel able to do it yourself. Instructions do come with the kit, tho.

    If you were here, I'd be happy to show you how to change the battery and supervise while you did the swap.

    Thanks everyone, I took in it to get tested at auto-zone and the battery is apparently bad. I saw the one I can order online for $200 from the post above. I have a friend who said he would put the battering in but does anyone know anywhere I can get a cheaper battery or is $200 as good as it gets?

    Technically, you could use a mower battery from Walmart, not sealed and not deep cycle but a lot cheaper. It would help if we knew what size the posts are on you current battery, they can be either about 1/2 inch or 3/4 inch. You can get the Optima D51R at Amazon for about $173, but it has the smaller posts and doesn't include the smaller connectors like the kit does.

    Be warned that some are recommending you sacrifice you and your passengers safety for money. Never a good deal. Buy a battery that protects your loved ones!
