    oh I found the fineprint at the bottom of the page large one 36 AH, small one 28AH, but they do have a brightly colored top, and they are just as pricey as the toyota ones.

    man I could have bet money on this one, I knew it, but waitttttttttttt It comes with a 6 page instruction manual free, but you must call now, and they ship next day, cant get rid of them fars enough.

    My god, to those that like things like optima, I mean the brightly colored kind you see on tv all the time, ask somebody that has a clue before you buy

    hey john , I do have a question for you :
    Why do you seem to think a 10 hour cycle is different than a 20? I thought, 5.5 amps for 10 hours, or 2.75 for 20 is still 55 ah, just curious, 55 ah is good for me regardless, but you must know something I dont.

    It is easier for a battery to produce a high Ah rating over a 20 hour cycle vs. a 10 hour cycle since it only has to produce half as much current flow over the longer period. The battery has internal resistance which results in some of its chemical energy turning into heat as electrical energy is produced. The heat loss is proportional to the square of the current flow.

    A derivation of Ohm's Law results in this formula: I^2 x R = P
    where I = current, R = resistance, and P = power

    Thanks Patrick. What this means in simple terms is, the faster you discharge a battery the lower it's useable capacity will be. Conversely the slower you discharge a battery the greater it's useable capacity. Google "Peukert effect" to learn more.

    Paphillyman, Yes that battery will fit. It is a slightly lower capacity than the Ritar and I am unsure if that battery is vented, but it will fit the application in the Prius.

    The OEM battery is vented as are all agm batteries, it's realy a matter of being able to pass the gasses if any produced by the battery to outside air. The origonal Ritar battey is supplied with a vent tube, so if it's being advertised as a Ritar replacement so should the battery they are supplying, if it is not with a vent tube it is not a suitable Ritar replacement.

    The lack of, or availability of a vent tube does not in any way alter the operation of the battery but some quite understandably are not happy to use a battery without. This must be your decission if you cannot find a battery with a vent tube.

    The OEM battery is an AGM battery as are the mobility batteries and the charging requirements are the same. The Prius does not have a conventional 12 volt starter motor, so does not require a starter battery, and does not have an alternator. The question must be asked how much does the "battery guy" know about a Prius. Does he know these facts, most non Prius owners and a supprising number of owners do not know or understand the workings of the cars.

    As I mentioned earlier in the thread, Mastersafe by Ritar might be worth looking into:

    RA12-55 - 12volt 55a/h - Sealed lead acid battery for UPS and Telecom, RITAR RA12-55 RA1255 - xpressBatteries.com

    Actually, the above is shown to be a "Ritar" battery (55AHr at 10Hr rate) being sold alongside other "Mastersafe by Ritar" batteries. Plus it seems to be cheaper than the one you asked about. Might also have the vent tube provision...

    Only in America can you buy a wrecked Prius for a few grand, partially repair it and tour the USA for nearly 6000 trouble free miles!
    No issues with the battery whatsoever!

    If you’re in Canada looking into Gen2 battery options:

    Dealer
    32Ah large w/smart-key battery (dealer quoted $203)
    (I didn’t check the price of the smaller 29Ah non-SKS battery)

    www.saskbattery.com
    38Ah Optima Yellow Top for Prius ($185 shipped). It has the right terminals and uses the stock vent tube.

    www.batteryspecialist.ca
    45Ah Exide Edge (Group S46B24R) FP-AGM51JIS for Prius ($145 + 35 shipping). It has the right terminals and uses the stock vent tube. They also have a good price on the Battery Tender Plus.

    Mobility
    I found many U1 and 22NF mobility batteries at Saskbattery.com Optima battery, odyssey battery, Deka battery, rebuild drill batteries, inverters, , SLA-Sealed Lead Acid Batteries - 12 Volt SLA Batteries - Battery Specialist, Battery Buyer - Batterybuyer.com, etc.

    All of them have flag terminals and would need a bolt-on adaptor to the Type A3 JIS Pencil Post, or modification of the car’s hookups. I was not able to find similar batteries with threaded terminals. All that I have seen have slot-vents that would need to be modified if you wanted to continue using the Prius vent tube.

    Non-SKS Prius?
    If you have a non-SKS Prius, your options are Toyota OE or Group U1. Other posts say that the Optima will tightly fit into the smaller battery tray, perhaps with a lopsided clamp or longer bolt?

    To increase Amp-hours with an S46B24R or 22NF battery, you need a “battery tray 12 volt w/”smart key”, which the dealer sells for $26 (much cheaper online in the US, as usual).

    Cheers.

    Yup same here.
    Earlier i was also wondering for fitting mobility 12volt AGM battery matter but now it seems that ending time is come.

    Decades ago, I worked with industrial grade lead-acids. There were drip pads of loose woven fabric that was filled with what I recall was baking soda (real high tech - real cheap).
    Does anyone know if: it was baking soda, and whether a drip pad would be a prudent measure in a Prius?

    BTW, PriusChat is MUCH more mature and at least semi-professional and beyond.
    In other forums, this thread would have gone nuclear at the first question of bona fides.
    I wonder if that is related to the average age of the forumites?

    So long as you've got your vent tube properly attached and routed, I don't see a need for that.

    Has any body ever opened up a Toyota batt. to see if the vent is actually functional.

    Yes, I have; and yes, the vent is functional on the original battery.

    Thanks. I want to replace the original 08 Prius batt. But the only one available in my area is a UB 12550 12 V 55 AMP which has no vent hole. BUT, I see no need if it is a SEALED agm batt.

    I just did one. No vent tube. Sealed AGM. It was $115. I did swap out the battery mount. It wasn't as clean I would have hoped but it's working well after only a week.
