    Simple topic, I am not a smart person at all. I am just trying to find out the name or part name or whatever that I need for a 12v battery for a 2007 Prius.

    IF you go to an auto parts store or the dealership and tell them you have a 2007 Prius, they can look up their part number for you for the 12V battery.

    Here's a thread on it

    Best deal I've seen recently is online order at PepBoys and pick it up at the store. Free installation if you want. It's 20% off online, probably full price if you just show up at the store. $165 + tax for a Bosch group 51.

    does the 2007 have the sks and non sks 12v sizes?

    you can start at a dealer, and go from there.

    Not as far as I know. I helped a friend install one in a 2008 and there wasn't any question about SKS versus non-SKS. Gen1 seems to have at least 3 different sizes, but Gen2 has settled on group 51 (or is that 51R?).

    An non SKS is a smaller battery. An SKS battery is bigger and will not fit the clamps.

    The buzz word for the right battery is S46B24R.

    Would any batteries from walmart work for the short term? Moneys tight at the moment. Thank you.

    jut about any 12v battery will work, but safety is another issue.

    Yes and no. Ideally you want a battery with an external vent tube for potentially dangerous gases since the battery is mounted inside the car unlike most other vehicles.

    Go to this list, post # 1, and scroll down to the section titled:
    "12V Absorbent Glass Mat (AGM) Valve Regulated Lead Acid (VRLA) battery, JIS Type 46B24R (NS60) (BCI Group No. 51*), Terminal - JIS Post / Pencil Post"

    (https://priuschat.com/threads/batteries-list-prius-2nd-gen-2004-2009-april-2018.194709)

    No. 1 to No. 10 are a list of drop-in 12V batteries for the Toyota OEM S46B24R battery.

    The best buy is probably No. 2:
    Bosch 51-440BAGM 45Ah 29lbs (13Kg) 4-Yr Replacement Warranty $154 (190 - 47 + 11) installed, $158 (190 +15 Core -47) in store (Pep Boys)
    (https://www.pepboys.com/product/details/647478)

    No. 11 is the tray needed to switch from the smaller S34B20R battery to the larger S46B24R size.
    74431 74440-47020 $20 (eLearnAid), $14 (McGeorge - VA), $15 (ToyotaPartsDeal), $21 (Toyota List)

    If you want a non drop-in replacement with a higher Ah capacity, scroll further down to a section titled:
    "Non-standard replacement for 12V AGM VR sealed lead acid (SLA) battery."

    If you want to try one of these, pay attention to the note:
    Not drop-in. All need terminal adapters to convert from 6mm F11/F14/IT/C, 8mm F10/F12/F15, or NB/Flag posts to JIS Posts. Requires larger battery tray for S46B24R, Toyota P/N 74440-47020. All will fit, but may be tight, and battery compartment cover may sit up slightly.

    The Power-Sonic PDC-12600 battery (60/55Ah 650/300cycles) with the Universal Post with 6mm hole may fit without terminal adapters, or maybe not, I have no experience with it yet. $149 + $36 Shipping (Battery Center GA, USA).

    This would only be for the very short term. Would a lesser battery be ok, granting one at walmart would work for my car, for the short term then?

    I appreciate the reply but it doesn't pertain to my current situation. I need something cheap for the short term like the batteries at walmart and was trying to see if those would be ok. Thank you though.

    Yes, just need to make sure battery posts are in the same location and size is close, etc.

    the correct battery has different attachment posts than almost any other car battery. While converters exist, they would need to be mail ordered.

    Installation Kit for Optima battery in Prius

    Once you convert it, it is not clear if the correct battery will fit. You will need to 'unconvert' it.

    Walmart sells a BCI Group No. 51 size battery (51R has the wrong terminal placement, don't get that).
    EverStart Maxx Lead Acid Automotive Battery, Group 51 - P/N MAXX-51 $105
    It will fit in the compartment if you have the tray for the larger S46B24R battery. However, the terminals are the larger standard SAE posts instead of the S46B24R's smaller JIS posts / Pencil posts. The cables will not fit over the posts. Adapters are available, but that is an additional cost and hassle.

    $105 for the improper wet cell Walmart battery versus $154 for the correct Bosch AGM VR battery installed at Pep Boys. The Bosch battery is the proper choice between these two.

    Also, the safety is an issue. The Prius should have an AGM Valve Regulated battery and the hose should be hooked up to the vent hole for safety (in case hydrogen, or worse, very poisonous hydrogen sulfide is vented out in a high pressure failure situation).
    The Walmart BCI Group No. 51 battery is not an AGM VR battery and does not have the proper vent hole to attach the hose to.
    This battery is a standard wet cell type, with free flowing liquid sulfuric acid electrolyte inside it.
    The Walmart battery is not safe for regular or long term use in a Prius, long term being more than a day or just for a very short term emergency.

    If you buy the Walmart battery, you are wasting $105. Spend $49 more and get the correct and safe Bosch battery.
    If you buy the Walmart battery, you are playing with fire ... or in the worst case, your life. I obviously do not recommend using it in a Prius.

    "In June 2016, a mother and her daughter were found deceased in their still-running Porsche Cayenne SUV against a guardrail on Florida's Turnpike, initially thought to be victims of Carbon monoxide poisoning. Their deaths remained unexplained as the medical examiner waited for results of toxicology tests on the victims, until urine tests revealed that hydrogen sulfide was the cause of death. A report from the Orange-Osceola Medical Examiner’s Office indicated that toxic fumes came from the Porsche’s battery, located under the front passenger seat."
