    Hi all,

    I was wondering if anyone has had to replace the lead-acid battery yet (not the hybrid battery). The reason I ask is the sale person told me Toyota makes it hard to get to on purpose to prevent people from messing around with it and that it is next to the hybrid battery in the back. If anyone has had to replace it, did they have any difficulties? Did it cost extra? Did you get it done at the dealer, at a third-party shop or do it yourself?

    On my old Chrysler Cirrus, the battery was in the wheel well and it was difficult to find a place that would do in an emergency. (Hard to drive all around town with a dead battery).

    I think others have found replacements (vague recollection), but do a search for 12 V Battery Replacement and you might find someone who has actually done a replacement. I know there have been discussions about this.

    I did a search but did not find the answer to my question. A lot of people have replaced the 12 volt battery, A lot of people have given reasons for a dead battery, but no one has given any indications about how difficult it was.

    If anyone has any answers, please let me know.

    Thanks.

    have to replace mine last week, got a aftermarket replacement from here, and actualy it is a little shorter in heigh but with claims of better performance, only time will tell.

    It takes some labor (I do not mind that), nothing major and cost less than half the Toyota asking price.

    Apparently these batteries do not last to long, mine is a 2004 production, and with the cold weather make it to discharge abruptly.

    Replaced my aux battery on my 05, it kept dying, I like to leave my siruis radio on so I can skip commercials. I got a type 51 as mentioned in a post somewhere, it wasn't too difficult. Did replace the connectors because they are bigger. The ground strap was easy just replaced. The one that goes to the positive was a little more difficult but found a piece that bolted on in place of the existing one. Seemed to fit fine.. and no more dead battery in the mornings. Its the 51 not 51r, the r has the positive in the wrong place.
