    140,000 miles. Many hours used as power source. Just looking for any updated info other than what’s already been posted. Thanks!

    Have you seen my previous postings about this, and in particular, the possible ACDelco and Duralast substitutes I mentioned in the second posting?

    (Ignore the discussion of AGM batteries; some people like them, but they are not the original type.)

    I don’t have any experience with the Duralast H4-DL batteries I mentioned, but I think AutoZone still sells them. You have to give their website a ZIP code near a store that has one in stock before they’ll show you a price; if you put in 90026 (Los Angeles), it’s $135 plus core charge and tax.

    I’d verify the physical size of the battery and the diameter and arrangement (+ and ) of the terminals before buying one, of course, but if I needed a new battery for my Prius tonight and didn’t expect a warranty replacement from Toyota, that’s probably where I’d start.
    For the fourth-generation Prius, there are two types of hybrid vehicle batteries (Li-Ion or NiMH), depending on the trim level, but all of the models use the same type of 12-volt, lead-acid auxiliary battery.

    Toyota finally updated their battery application chart (PDF) for the U.S. market. For 2016 and later Prius (“ZVW 50, 51”), it lists only one replacement 12-volt battery, with the code “H4” and the 00544-H4052-470 part number you mentioned. If you’ve seen other Toyota battery part numbers beginning with 28800, those are manufacturing part numbers, not generally available through the U.S. parts system.

    Is there an American distributor for the ACdelco replacement battery?

    Would the higher rated Duralast have any known negative affects on any systems on the car? Thanks ahead. You’re post is very helpful and cleared some misconceptions I had. I’m gonna size check the Duralast hopefully tomorrow and check back here. (Also, links were taken out of your quote b cause this makes a new member wait a day before allowing quoted links or something.)

    You’re welcome, and whatever you decide to buy, please do let us know how it turns out.
    The ACDelco LN1PS should be available at Chevrolet dealers in the U.S., as part number 88864528. I don’t know of a U.S. source for the ACDelco 355LN1, which I think may be sold only in Japan.
    I can’t think of any.

    I read the rest of your posts in that older thread. If I check the level on my oem battery and its low, is it a safe best and I can get a couple more years with some distilled water? It has been a STOUT battery for the amount of miles and use.

    Reason I ask is because the Duralast h4 is no where to be found anymore apparently

    If that’s actually the problem, you might be able to lengthen the service life some, but I have no idea by how much. If the battery has already been tested and found to be defective, I’d suggest replacing it.
    Did an AutoZone store tell you this, or are you just having trouble finding one on the AutoZone website, which doesn’t make this easy? I’m not sure where you are in Los Angeles, but supposedly they have one in stock at 1515 N. Alvarado. I imagine any AutoZone store would be able to get one, though, if you can wait a few days.

    I had the same problem with my 2005, they replaced it gladly. In warranty.

    I measure 3 months for 2017 and ONE year for 2016,or less.
    I was having battery problems in 2005, 12 V, I drove to the dealership in the morning and then proceeded to leave the car in accessory mode and turned everything on I could think of while waiting. Probably did not even wait 10 min. A healthy battery can sustain that short period. They declared I had a bad battery, and replaced it free of charge with a free rental, overnight. If I had not strained the battery, they may have declared it good??

    Are you saying your battery is older than your car ?

    36,000 miles is Toyota’s limit.

    Here we go again! ALL lead acid batteries use up water. They all loose -some- water to hydrolysis, some less than others.

    Yes, topping up the water with distilled water can "fix" the battery. In my case, a 3 year old battery was made "like new" and is still working fine at 10 years old, but that is rather exceptional. Most will last another 3 years minimum.
    Just because some "technician" says it needs replacing doesn't mean it does. Adding water is very inexpensive, -if you can-. It's worth a try!

    Sounds to me like the OP wants to just persist in buying a new battery, no actual facts given, just hearsay..........is it charging to 14.5 volts? what is the charge in the morning before driving off????

    The 12 volt battery is covered under the comprehensive warranty that has a 36,000 mile limit. I checked the manual.

    He did mention he'd done 140K miles, so I guess it's reasonable that he's wary of leaving it.

    OK, People have been measuring battery efficiency by years. not miles. I would just keep checking the actual voltage levels everyday until it inspired so much confidence that I’d be tired of checking.
    If he’s worried about getting stranded, there are several emergency batteries on the market, as well as trickle chargers. The battery is only THREE years old!

    Constant, proper use is probably a plus for battery health.
