    From a customer who bought this battery. "Hey I just wanted to let you know, I put the battery in today and it works great!

    The instructions were perfect, and it took about 40 minutes from start to finish to get the old one out and new one in.

    Have a good thanksgiving if you haven't yet already!
    " Romeoville. IL

    From customer how bought a similar battery. "Battery dropped right in, fits perfect. Very easy install in Prius V, no duct work or electronics in the way. Literally under 30 minutes, needing only a ratchet, 3" extension and 10 mm socket, including jumpering the terminals in front to maintain all the data." K. F., Guam

  • Prius C: This battery has the same height, depth, and vent tube connection however it is a little wider. It does fit merely by bending one bracket.

    We have sold this battery and one with American style posts for six years and have thousands of satisfied Prius owners. We provide detailed instructions!

    "Hi Friends

    The fruits of your efforts are greatly appreciated! I know that the battery is just a small part of your play in peoples lives, but it's a big part. In the way you made it easy and confident. The instructions top notch!

    Shipping.. A guy came by in a small white van and left it with a smile. I'd say it was first cabin all the way.

    I'm sending back the box and its ingredients for a journey to another place.


    a fan Jamas
    " [customer send us back the box with all the padding so we could reuse it and he even included a bunch of plastic frogs!]Click here to see his hand written note.

    "Just letting you know I installed the battery Sat evening without any trouble. Took me about 45 min. (That didn't include 10 min searching for a second socket extender.) Not bad for a small 56 yr old female who has a desk job!

    The instructions were very clear. I didn't have magnetized tools and was having difficulty with the vent duct bolt behind the liner, so I used a small piece of tape to keep the bolt in the socket while I got it started. Then it was easy to reach in and remove the tape and tighten the bolt the rest of the way.

    I've emailed all my Prius buddies letting them know about my experience w/your product.


    G. C., San Diego, California

    "I want to thank you for the help and service you supplied me. The instructions included were spot on and easy to follow. The total time to change this battery out was 15 minutes start to finish. The packaging was bullet proof the battery arrived 1 day ahead of promised time, safely. The cost savings was also a blessing. Toyota wanted 230.00 plus 30.00 destination charge. To get the battery from Orlando to Melbourne Florida . The dealer did not have one in stock. To top that off they wanted 75.00 to install it. Finlay the Toyota battery comes with a one year warranty period. Thanks again for all your help and support.


    D. M., Palm Bay, Florida

    "Thanks for the record setting fastest ever delivery of my order! [we hand delivered this one.]

    I installed the battery quite easily in my 2010 Prius with no problems at all. It is really an exact direct replacement, fits perfectly, and I am quite pleased.

    Has your 12 volt battery failed?

    If you need a battery for a 2000, 2001, 2002 or 2003 Prius click here.

    Price includes:

    The Toyota GS Battery has free liquid acid that is not absorbed in the glass mat. Consequently, it can not be easily shipped to you. So if you wait till your battery is completely dead you might have to go to the Toyota dealer near you and pay whatever price they charge. PLEASE DO NOT WAIT! HOWEVER, WE DO SHIP Next Bus. Day if you are in CA, A metropolitan area AR or NV. (see map) and by Air so we can GET A BATTERY TO YOU IN 1 to 2 DAYS to most of the US 3 days max.

    Also Prius owners have told me the Prius acts very strange when the 12 volt battery gets weak they get error messages like: "P LOCK MALFUNCTION WHEN PARKING, PARK IN FLAT PLACE AND APPLY PARKING BRAKE SECURELY." Your MPG can also drop because the ignition and the engine computer and all the sensor are running on 12 volt power. So if the battery is dragging down the voltage if can cause poor combustion and engine control.

    This is the ideal battery for the Prius. We have sold them for since 2009 and the battery has a less than 1% failure rate in the three year warranty period and I am getting very few repeat sales! On a Prius the 12 volt battery does not start the engine the high voltage battery does. You do not need the RED TOP battery which is chemically configured to provide a lot of starting power. Instead you need a battery that can handle the slow stead drain than occurs when the car is parked. The drain is from the clocks, the memory chips, the security system and the remote entry and key less starting system. THIS BATTERY IS DESIGNED FOR THE DEEP DISCHARGES THAT THESE SYSTEMS CAUSE WHEN THE CAR HAS BEEN PARKED FOR A WHILE. How much work is this to install?
      Normal car:
        You pop hood, disconnect battery terminals, unscrew hold down bracket replace battery and then attach above and close hood.

      Prius 2010 +: normal + the battery vent tube connections +removing rear hatch floor paneling and storage tray. (Very easy install.)

      Prius 2004 to 2009:

        Open trunk.

        Remove floor and plastic panels.

        The mounting bracket is a little harder as it requires a socket extender because there is plastic box in front of this.

        You also have to disconnect and reconnect the ventilation hose that connects to the battery but that is not a huge challenge.

        You also have to remove and reinstall a ventilation duct. (two bolts and a little finesse [explained in the instructions])

        So it is more work than a traditional car but very doable if you have the tools!

        Minimum tools needed:
        • 10 mm wrench or 10mm deep socket
        • 10mm socket
        • socket extender 5 inches or longer (you can put two together)
        • tape
        • straight edge screw driver
        • a small battery or jump start battery to maintain the 12 volts in the Prius so you do not loose any presets. (Optional but recommended!)
    Our free shipping is next business day ground (to the California and western Nevada, including: Las Vegas & Reno & Arizona including: Phoenix, Flagstaff & Tucson ) or Priority Mail (2 to 3 days)! See the map above. If you need the battery as soon as possible let us know in the comments or call us at 818 364 9810. We will do what we can to get it to you as soon as possible!

    The three main contributors of premature battery failure are:

    1. Vibration which causes distortions in the plates and eventually shorts.
        This battery is made by sandwiching the acid filled mat and the lead together and then tightly inserting them. This reduces vibration failures by 15X.

    2. Repeated deep Discharges
        This battery has graphite to handle repeated deep discharges. Leaving the lights on a few times will not kill this battery! My battery in a 2001 Prius is dead at 10 years old but only after receiving the abuse of charging up 7 hybrid battery modules and then not being charged up on a charger.!

    3. Heat!
        Yes batteries have less output when cold but they also last longer. In a Prius that is partly handled because the battery is in the trunk not the engine compartment!

    If you want a battery that lasts longer. This is it! You will pay about the same at a Toyota Dealer but this is a better battery! We offer free shipping on this battery via ground to the Southwest and or Priority Mail to the rest of the 50 states Hawaii, Puerto Rico and other US territories! You should have your battery in 1 to 3 days!"

    This battery can replace the Toyota 12 volt battery for the Prius with Smartkey or navigation system Toyota part number 28800-21170, now 28800-21171 (GS Battery # S46B24R) or for a Prius without the Smartkey or navigation system Toyota part number 280021050 if you order the additional tray.

    The Federal Magnuson-Moss Warranty Act of 1975 prohibits a manufacture from curtailing warranty coverage due to after market parts unless it can be demonstrated that they caused the problem. (For more information click here and scroll down go to paragraphs under "Tie-In Sales" Provisions.)

    This sealed battery has little free liquid electrolyte because it is absorbed into the glass mat. Consequently, there is little acid that can spill into the trunk even if the case cracks. It also has attachments for a vent hose so any gases are vented outside of the car. The battery does not normally emit gases but can do so with heavy over charging with pressure building up and the valves in the batteries releasing. This should not normally never occur because the Prius high voltage to low voltage converter puts out around 13.8 volts. 13.8 volts is the voltage the battery puts out at no load and at that voltage the battery can not be overcharged and it is the maintenance voltage for the battery. However if one cell shorts out or the voltage unexpected goes high gassing can occur.

    The 12 volt battery is not used to crank the gasoline engine in the Prius but it does supply all the 12 volts circuitry which includes all of the computers in your car. If this battery fails, the computers will not start and the Prius will not start. A weak battery can also pull the 12 volts power down to a lower voltage. This can cause problems with all of the computers that control your car. (When I had a problem with my car the first thing the dealer insisted I do was replace the battery. The problem was caused by something else but the battery was weak.)

    Since the 12 volt battery does not start the gasoline engine you can still use the car with a very weak battery. So much so that at least three Classic Prius users have told me that their Prius now gets better mileage with the new battery. I am now starting to get these stories from 2004 + owners also for example:

    "The MPG skyrocketed in my car after the battery replacement. I was getting 37mpg on the freeway and now its over 48mpg. Thank God!"

    So if your 12 volt battery is very weak and your MPG has deteriorated a weak battery could also be affecting your gas mileage.

    If in doubt check the voltage after the car is started. (see procedure below) If it is at 13.8 volts or higher then the high voltage to 12 volt converter is operating and charging the battery and it is probably not the battery that is causing lower MPG.

    Has your 12 volt battery failed? Prius battery test procedure for 2004 to 2012+ Prius Cars

    Prius not starting?

    The traditional load test is for 12 volt batteries test your battery ability to crank the engine. The 12 volt battery on the Prius never does this. The high voltage battery does. (So you might be able to get a few more years use out of a battery that fails the load test. However, the less capacity your battery has the shorter the period that you can leave your car parked before you need a jump. It can also affect mileage.) The 12 volt battery only has to maintain the electronics in the car (security system and remote sensors) while the car is parked and then have enough juice to start all the computers and all the 12 volt systems in the car on start up. Once you have started the car a high voltage to 12 volt converter takes over and charges the battery.

    So perform this test after the car has been parked for as long as it would be normally parked to see how the battery holds up under the drain from the security system, clock, memory chips etc. Ideally first fully charge your battery with a charger for sealed lead acid batteries then let the Prius sit parked. (If the Prius is not driven much the charging is very important.)

    • The transmission should be in Park with the ignition off.
    • Engage the parking brake
    • Push in the power button. (if not already on)
    • Press and hold the "Info" button on the MFD while turning the headlights on and off 4 times.
    • Push on Menu in upper right of display screen.
    • Push on Display Check
    • Push on Vehicle Signal Check
    • You will see the 12 volt voltage displayed. In accessory mode the voltage should be 12.6
    • With no electrical accessories on including lights the voltage should be fluctuate between 12.6 and 11.9. The lower the voltage, the less of a charge your battery currently has. If the voltage is low do not proceed as the load test might totally discharge your battery. (If you see a voltage around 13.8 you are seeing voltage from the high voltage battery being converted to around 13.8 in an attempt to recharge your battery. This normally does not occur till after you start the engine but might occur earlier if the battery is very drained.)

    • You can also test the battery by turning on the headlights, rear window heater and the heater fan. For a new battery the voltage would be around 11.3. If the voltage drops below 10.2 it should definitely be replaced. For voltages in between the lower the voltage, the lower current charge of your battery.
    • Push on the brake pedal and push start. You should see Ready in the Speed display. The voltage should now read between 13.8 to 14.2 and higher in winter. This is the charging voltage!

    2004 + Prius DS46B24R Battery Customer comments:

    "Toyota didn't make it as easy as most cars to swap a battery, even switching between 2 metric socket sizes from screw to screw. I took it slow and careful and it took under an hour from start to finish with only one skinned knuckle.

    I was a little leery about buying a battery from a book site, but the price was compelling and no local auto parts store had it in stock. The transaction couldn't have been smoother and the battery came in perfect time, right before I had to go on a long trip.

    Kudos for helping the Prius owners community with a good product and great service.

    G. G., Hillsborough, NJ

    "Thank you for the wealth of information on your site for the battery replacement for a Prius. I placed an order last week (elearnaid-25428) and received the battery in a day or two. I did the installation this weekend and was pleased with the detailed instructions. The instructions made it a very straight forward installation that took less than 45mins, even with time out to vacuum the trunk and spare tire well while I had it opened up."
