#118 of 149 How do you charge Prius Batteries.
Aug 17, 2009 (3:35 am)
Hi everyone new to this site. I am an over the road truck driver. I have a 2003 Toyota Prius that I have not driven since October of 07. It is completely dead. How do I recharge the batteries. I called the dealer and asked them they said that I should have jumper posts under the hood, but I can not see anywhere to connect cables to. Also should I use a trickle charger or just jumper cables connected to another vehicle. Any advice would be helpful.

Wow, a 7 year old battery that has sat for the last 3 years??? I believe I'd just replace it.

Replace the small 12 volt battery at a dealer. There should not be an issue with the traction battery. Once you get the car started you may want to consider having someone start it periodically for you. I know what it is like for OTR truckers and sometimes you're gone for close to a month (depending on who you work for). Good luck and keep us posted!!!

Intermittently when my wife goes to get in our 05 Prius she will get a long steady beep until she gets in the car and closes the door. I have checked out the manual and replaced the battery in the key fob. She tells me it is still doing it. It has never done it for me. I am suspicious of the 12volt battery. Any thoughts out there?

The 12v battery will give some other warnings that it is in need of replacement. If I were you, I'd check the voltage and make sure it is around 13.8 +/- Also, check the operation of various electrical components without starting the vehicle. Based on the fact you have an 05 it may be time to change it. It is good preventive maint because they last 4 or 5 years. I just changed mine and I have a 2004. I bought it online for $107 shipping incl and installed it with a friend.

Thanks for the info. That $107 sounds like a good deal. Can I ask for the link?

Just do a search on cheap Toyota parts. It was a year ago that I purchased the battery so I don't recall the dealer. I'll look at my receipts and see if I can find it. I know the dealer had a web presence so it should be fairly easy to find. Many dealers won't send the battery because they consider it hazmat, but this particular dealer had no issue with sending it. I do remember receiving it via DHL and they no longer ship domestic. That may effect how the dealer charges for shipping. At any rate, the list price for the battery is 125-150 just not sure. If you are handy, there is an alternative battery that you'll find in your search that many people are using. Again, when you search for 12 volt prius battery you will see a wealth of information. Good luck!!

I checked the voltage, and it was about 12.3v. I then checked the voltage on our new 2010 Prius and it was 12.5. This with everything turned off. With everything turned on, it rose to 14v.in both cars.
It's a five year old battery and I don't want my wife stranded just to get more out of an old battery so I am going to replace it soon.
I did a search as you suggested, and found a ton of great info. Thanks.

I'm glad I was able to assist. Based on the readings you obtained it appears that the battery may not be bad, however it is not an expensive item and as a preventative measure good to change BEFORE you start having issues. With my situation it died because I was not using the vehicle for quite some time and though I did charge it, it never revived. I got five good years out of it. I'm pleased. So far my 2004 has been more reliable than any other vehicle I've ever owned.

This is actually an AGM battery and Toyota is the best place to buy them.
