Gary Browne: Ryan,
Sure appreciate that you took the time to do your video and help others
like myself! I changed my wife's 2009 battery. Best regards. Gary Browne
Rex Takasugi: Very useful video! Without your video, I think I would have just taken it
to the dealership as it looked kind of complicated with all the electronics
and air vent tube to remove. Thanks!
J.W Kim: It's like searching for the right hole on your first sex.
Linda A. Noble: What source would you recommend for purchasing the battery? Any particular
things to look for or avoid? I'd like to try to do this myself too. Thanks!
8180634: @lakssampath It looks like it's a direct fit, thank you VERY much for
posting the Optima part number!
Eve Soto: Not all Pruis are created equal... Am I missing something but I don't see
what year model is this Pruis...
danwat1234: It is for 12V accesories as the dash board and radio, windows use 12V
power, it uses a 12V battery to power these devices. I know, you're
thinking why not just use a power converter from the main battery pack to
convert down to 12V. Well, the problem with that is that it would have to
be running all the time even if the car is off, so the clock keeps working,
radio presets, door locks, and then would use a lot of energy and
eventually you might be faced with the expensive pack being low on juice
Paul Priz: thanks, very helpful!
danwat1234: So they use a 12V battery to supply the accessory power when the car is off
and when on there is a power converter that converts power from the main
pack to the lead acid battery.
Ryan Bailey: without this battery you will not be able to 'start' (power on) the Prius.
Never heard of such nonesense. Your friend must have done something wrong.
If you like you can hook up a trickle charger under the hood to the
terminals but it is not necessary. Biggest issue is reprogramming your
radio stations and having your car relearn your driving habits. Glad I
could help you.
Ryan Bailey: Yes, second Gen.
nihonsuki: This was a big help. I just wanted to add that there's a small rubber hose
and elbow fitting that go into the left side of the battery near the +
terminal which will have to be inserted into the new battery. The elbow
fitting was fastened to the old battery with a drop of glue which I broke
to remove the fitting. The loose slide fit into the new battery seemed to
be enough to keep it in.
charles ben: thanks i did it it was very easy it took me 45 minutes took my time thanks
again have a great day know can i charge the other dead battrie and save it
for rea acid it at a repair shop im going to check it out thank you again
GoMetricToday: I have a 3rd Gen.
Laks Sampath: Thank you very much for the detailed instructions. In a matter of less than
2 hours I removed the old starter battery and put in a new Optima DS46B24R
YellowTop Prius Auxiliary Battery for my 2006 Prius.
moxncal: i dont get this, they use tons of nimh batteries for the engine and they
still use lead for the car battery? damn toyota techs!, they need to do
away with the lead acid battery!!
fredronquist: @rrbcap Regardless of battery size, the procedure is exactly the same. The
video is great; the manual does not give enough instructions on how to
change the battery. Apparently you can change the brace in the bottom of
the battery compartment to fit the larger battery, which might be a good
idea for us living in a colder climate (we're in Sweden now).
brianflower45: Thank you! Saved me money and with your video look about 30 minutes.
d46512: Yeah but you only need to change it every 5-6 years.
Ryan Bailey: @jaxo1 You're lucky you got anything :). I'm sure you can find another full
video somewhere. Good Luck!
Joseph v: Just replaced mine, battery's must've gone up looked around spent 2 bills
and dealer wanted 350..figured it was worth 40 mins of my time....slow i
know, i was careful! thanks man!
Ingvar Humanus: Two questions. 1. Volt is not much different in principle design from any
other hybrid drive. Still and ICE and battery and MG. What made you go away
from Prius, and go for Volt and sort of sound derogatory about Prii?
Reliable they are, that is the fact, have not seen a single Volt as a taxi.
2. What exactly this means: Move along now please.
Linda A. Noble: Thank you! I will call the dealer now and order it and cancel my
appointment at the same time :) I'll let you know how I do.
Ryan Bailey: @turdsandwicher agreed. Fun to get to too.
Ryan Bailey: @fredronquist You are exactly correct. There are aftermarket conversion
kits to fit bigger batteries. I was surprised I got 7 years out of the 12V
Battery but was shocked on how much the dealers wanted to charge to just
change a battery.
Ryan Bailey: You are very welcome!
lgatzow16: Thanks so much for the video. Hubby & I replaced our original auxiliary
battery in our 2006 Prius with the Optima DS46B24R (company is offering a
$25 rebate at time of this writing), plus we received a 15% discount at
Advanced Auto Parts off their list price (in case anyone out there is
looking for a deal). Thanks again!
Ingvar Humanus: 1. This is not starter battery. HAS NOTHING TO DO WITH STARTING ANYTHING.
2. USE BACK UP BATTERY WHILE REPLACING THIS ONE, HOOKED UP PARALLEL. Unless
you want to see "Check Hybrid Drive" message on display, and have car not
starting. That he didn't, does not mean you won't. I know at least one guy
who had to pay $520, as a result, by "simply" disconnecting 12V battery and
Bill Furlong: Just encountered needing a new battery as well. Thank you for making this
really easy to understand. I too will save dealership money and do it
myself, thanks to you!
Ryan Bailey: Ingvar, the Volt is much different than the Prius. I don't want to get into
a disagreement with you, not worth the time and effort. :). 1.) The Volt is
all electric drive all the time. 2.) Electric Heat. 3.) ICE serves as a
generator and it's sole purpose is to generate power to charge the battery
4.) I can run on pure EV and not use a drop of gas. 5.) Regen is much
greater 6.) Motor is 110kW motor. big enough to power 12 hours :) 7.) I'm
running out of room to add more.
TalmadgesArcade: Yes, can you post a "part 2" with the rest of the video? Thanks so much for
posting this, I will be following these steps tonight :) (2009 Prius)
fredronquist: Great help, thanks for posting. Slightly easier procedure for removing the
assembly on top of the positive terminal is shown on the related video by
briansmobile1, which is also very helpful . Be sure you get the right
battery size. Older 2G Priuses have a smaller battery (S3420R) while newer
ones have a larger (S4624R) one. It is claimed they changed to the newer
battery in 2004 but our Prius, a 2005 bought in Forida, had the older
Ryan Bailey: Honestly, I would just go with an OEM Toyota Battery. Just contact a dealer
and they will order you one. There are some aftermarket batteries you can
retrofit. It wasn't worth the time for me to mess with though.
Ryan Bailey: uh, yeah, that is why my initial reply to you said power on. Regardless, if
you have a dead 12V battery you will be stuck along the side of the road. I
owned one of these for 8 years and now I own a Chevy Volt. Move along now
Ingvar Humanus: It has nothing to do with starting, as in "cranking" starter. Neither Prius
nor Cmary Hybrid nor any other vehicle with Toyota Hybrid Synergy drive has
starters. ICE - internal combustion engine - is cranked by MG2, motor
generator 2. 12V battery serves only as a backup power supply to ECM and 2
auxillleris, one of them being a/c. So yes, if you have 12V battery dead,
vital electronics simply will not be able to work in order to power up
vehicle and in order for MG to start engine.
GoMetricToday: Is your Prius a 2nd Gen? My 12v battery is on the left side of of the cargo
fliegeroh: Thanks a lot. You are a lifesaver.
Michael Gallagher: Thanks RRBCAP, the battery replacement procedure went pretty smoothly, And
I was glad to have watched this first.
8180634: @lakssampath Did the optima fit as-is, or did you need any additional parts
to make it fit the connections?
rrobin1057: ???? where is your amp at i'm trying to find out where to put mine at a 4
Ryan Bailey: @fredronquist Interesting that your 05 had a G2 battery. Hope this vid
provided some help. I was looking for documentation on how to replace the
battery so figured I would make a little clip and save others some time.
turdsandwicher: freaking ridiculous where they place that battery....
Ryan Bailey: Glad I could help!
talu152829: Great video thanks
Ryan Bailey: @whole27 two different types of batteries. the Hybrid batteries will cost
around 5 Grand to replace. Maybe cheaper now since they've been out for a
while. I've got 135K miles on mine with no issues. Just had to replace the
12v battery and a rear shock and that is it.
joeybean11: THANK YOU for posting this and THANK YOU to everyone for the comments!
Getting the Optima battery from Advance Auto was a huge money saver, not to
mention that they were the ONLY store out of 5 auto stores that even had a
battery that would work. They also installed it for free!
jaxo1: It would have been a bit better if you had shown it from the beginning
instead of trying to explain what you had already done off camera.
Ryan Bailey: @buster111111 Yes, you can actually put a trickle charger on the terminals
that are under the hood. If you look to the left under the engine you will
see a little black box that houses the relays and some of the fuses. Pop
that open and there is a terminal (it is marked with a positive sign (+) to
hook up the positive side of a jumper cable or trickle charger. Simply
ground out the negative and you are set to go.
MrCuddlyable3: 2. is obvious to anyone except Ingvar Humanus who SHOUTED that the battery
has "nothing to do with starting". Rrbcap explained why that statement is
nonsense and Ingvar tried feebly to defend it. Check your dictionary Ingvar
and see that "start" doesn't have to mean "crank". So unless you have
something more sensible to say here, please SHOUT anywhere you like but not
