    Hi. I would like to replace my 7 year old 12V battery shortly on my 2014 Prius v. I have read older threads. What is the current thinking on the most cost effective battery replacement? I want one that fits without any jerry-rigging. I called a couple Toyota dealers and the best price I could get was $240 (with exchange). I will install myself. Is there any other batteries that are cheaper but just as good as Toyota OEM?

    they all seem to be pretty good unless you get a lemon. call around to auto parts stores.

    i paid 200 plus tax for an oem, it has a decent warranty

    The list price on the OEM Toyota battery is $225 and the best quality available. Your original lasted 7 years. I highly recommend using the original Toyota battery. I have had terrible luck with aftermarket batteries and great luck with the Toyota battery.

    Call around to auto parts stores and battery stores for an "exact replacement".
    Pep Boys if there is one in the area.
    ANY name brand AGM battery will be just fine.

    Likely that you won't save more than $30-40 by shopping around so getting one from a dealer is probably good advice.

    If you get them at generic store check the manufacture date. Cheap ones or ones on sale are usually going to expire.

    I just changed mine this wknd with the OEM one. I figured the original one in my 2012 lasted this long.

    Ask if the store has an electronic load tester, would be ok with testing it in front of you. Or score a SOLAR BA9, bring it along and test it. Cold Cranking Amps on a new battery should be well above spec, at least 10% over. Voltage should be at least 12.6. The testers usually give a verdict too, something like good, fail or good but recharge needed. The latter is common with a viable battery that sat a while.

    Advance Auto Parts (DieHard Platinum AGM Battery, Group Size S46B24R, 410 CCA S46B24R: Advance Auto Parts)
    states the following:

    Exact Fit for your 2015 Toyota Prius V Two
    REQUIRES PROFESSIONAL INSTALLATION: DO NOT attempt to install batteries in this vehicle.; Non-BCI group size.; Battery is vented to outside of vehicle.; AGM Valve Regulated Lead Acid [VRLA] is required; Installation may take up to 45 minutes. Battery located in trunk.; AGM RECOMMENDED: this vehicle is identified as having high electrical loads by a leading researcher; AGM Required: This vehicle is identified as having start-stop technology and high electrical demand.; OE Exact Fit; OE Spec: ****

    From what I've seen on You tube the replacement of the 12 v battery is no big deal. Just need a 10 mm wrench, and remember to re-install the vent.

    It's odd that the same page posts reviews of customers who installed the battery on their own after the above dire warning (?) and
    in questions and answers they talk about having it installed at the store. I haven't noticed any of these stores that have a service area, so they do this in the parking lot (?) and it take 45 minutes in the middle of the winter (!?) Enquiring minds want to know :)

    The price of their battery is $219.99, so if TampaPrius.com is correct, there isn't any real savings over having the dealer replace it,
    and I don't have to do it myself and buy one of those memory preservation devices. Also the question of reliability, it doesn't look like their 3 year warranty holds up well based on reading reviews of customers for other products.

    Our v is now 5 years old, and its time to think about replacing the 12 v battery. I'm inclined to have the dealer test it and replace it if it's time has come. Thanks for the input, it's very helpful.

    Mine was 325 installed with tax, I think the batter itself was $230 or around there. Likely an 8 year old battery, so darned good. Reminds me, have to ask them why my green light on the Start button doesn't go on anymore. The orange or amber one goes on.

    Yeah it’s not difficult or complicated. The hold-down bracket is an overly complicated mess with zero tolerance for battery height variation; when I replaced mine with an Optima Yellow Top I had to put a washer under one end to get it to seat level.

    Disconnect neg first, then positive; install new in the opposite order. Snug the clamps firmly with a small wrench, but as the Brits say: “Don’t go mad”.

    And connect the vent lol.

    While everything’s open the inside of the cable clamps; there’s a wire bristle brush you can get for this, or sandpaper in a pinch. And run fine sandpaper ‘round the posts on the new battery. Careful with the (lead) dust, and dispose of the sandpaper.

    I replaced mine recently with a Toyota battery. I used a 9v battery powered thingy that connected to the battery cables that kept the radio, etc. settings. Worked well.

    I see that Amazon has an AC Delco 24 month battery for $175. Don't know if it's as good as the Toyota one.

    A DIY no big deal. We went with the Optima Yellow Top, six years ago, and installed a CTEK charge indicator pigtail for the occasional reconditioning by CTEK 7300.

    That whole quoted paragraph is pretty much BS.
    The author seems to think that the ICE starts from the 12 V system.....which is NOT true.......and makes some erroneous assumptions from there.

    You mean in post #8? I concur, scare tactics. A place to avoid.

    I think this went over my head (?)

    I have a 5 YO battery that is probably near the end of it's useful life, and I would like to replace it for the lowest cost before we
    go out to start the car on a cold morning and find out that the battery is dead I don't know if the engine won't turn over, but I'm sure a dead 12 v battery is not good. I don't care if the 12v battery turns over the engine or not.

    Having worked at a tire shop and an ARCO station whilst in college, I've changed plenty of batteries (I even set some poor guys car on fire,
    while changing an alternator belt on a big block Pontiac). But that was a while back, and this car is unique.

    If you worked at a service station and changed batteries, it’s nothing you can’t handle.

    Hi fellas...thanks for all the helpful replies! I think I am going to go with Toyota battery. Called a couple dealerships and best price I could get is $240. I called Auto Zone and they has Duralast for $200 (3 year warrantee and free replacement). Since original battery has gone 6 years it seems like it is worth the $40 bucks to get the Toyota one. I will replace myself. I don't mind resetting whatever settings I lose during replacement. You guys are awesome- by the way!

    The primary reason why to use OEM.

    Thank you, I'm not concerned about the process of replacement, but this battery is an odd ball, and I want it to fit in the space without having to make any modifications, including the vent. I agree with Tony David, and others, that for the difference in price the Toyota battery is the way to go.

    I ordered this to keep the cars settings, only about $12.00 and plugs into the thing that used to be called a cigarette lighter, but is now a standard car electrical outlet :) I like it better (if it works!) than the one that gets clamped under the engine compartment and is no longer made.
