    I own a prius 2004 for awhile and I noticed that my batteries keeps dying after not using for 3-4 days in a row. I fixed it for 3 times already and still have the same problem. Any input on that. Thank you in advance.

    Perhaps whatever you're doing to "fix" it is not working. How are you fixing it?

    And which batteries exactly.....the small 12 V one or the big hybrid one ??

    Either way, if the battery is still the original one, it is now about 13 years old and needs to be replaced.

    Thank you for all the input. The history of the car: We used to change the whole pack of batteries, but then it broke down again because we didn't use for about a week or so in a row. Then we had the mechanic checked and changed only the slots that had less than 16 vol. And it worked fine again until I stop using for 3-4 days in a row. We have changed 4 slots for four times already.

    Should I change the whole pack again? Will batteries pack for version 2006/2007 fit with 2004 series? And is there anyway to maintenance the hybrid car like mine?

    Thank you :)

    here's the problem; you either have to put in a brand new pack from toyota, or just keep fixing these low quality replacements. it's your choice, low cost, or quality.

    yes, any pack from 2004-2009 will work.
