    I power goes on in the accessory mode so I can turn on the radio . I left in that mode for 15 seconds and tried to take off the brake slowly. Still, nothing. The battery indicator light comes on, engine light and brake light. I guess I will have to get it towed to the dealer. I don't understand as it has been less than 2 months. I thought being new, it would still start.

    I have heard terror stories of trying to jump start the battery. Any suggestions?

    Thank you

    If the dash lights up your 12V battery is good and has power.

    Just a clarification, you are pressing the regular brake pedal (not the parking brake) when pressing the START button, right? Any messages in the display that is in the speedometer?

    Got it going. I guess I wasn't holding the break down long enough and the steering wouldn't unlock.

    Thanks for tips.

    Glad you're up and running!
  • Does anyone have an idea of how long one can expect the 12V AGM battery to last?

    On another board the user SteveHansen posted;

    "AGM batteries typically do last longer than regular lead-acid batteries. The usual failure mode of a lead-acid battery happens when a plate warps enough to touch an adjacent plate, creating a short. The plates of an AGM battery are separated by fiberglass mat, which prevents them from shorting. Because shorting is prevented, the typical failure mode of an AGM battery is chemical, and failure is gradual instead of sudden.

    AGM batteries typically retain the hydrogen and oxygen inside the case, and recombine it to water, so they don't lose water. However, they also have overpressure valves to release the gas, when there is too much gas to hold. The gas venting occurs during periods of heavy gas-generation, which occurs during rapid or over charging. Gas production is increased by high ambient temperature.

    If you keep the batteries in temperature-controlled space, and never rapid-charge or over-charge, AGM batteries can last many years. In some communications systems "float" applications, for example, AGM batteries are scheduled to be replaced at 20 years, though premature failures do occur. But, if you over-heat and over-charge the battery, it can still "boil" the water, and failure can occur in a very short time.

    So, the life expectancy of an AGM battery depends on the usage, not the calendar. In automotive usage, in a particular model of vehicle, I expect the battery life depends on how smart the engineers were in designing the charging system. For TCH, we probably don't have enough history to know that, yet."

    Earlier today my 12V battery died/drained down - was a bit surprised, as I had just driven the car earlier on the day. This a brand new 2010 TCH, that I purchased just 2 days ago.

    Since I am still coming to terms with the key-less starter, it could be that I left the car on. However, I read in the manual that the car is supposed to shut down after an hour of staying 'on' with no driving.

    Everything worked fine after I jump started it - (Of course, I lost my mileage history and bluetooth presets).

    Is the battery a 'lemon', or should I give it some more time to charge up?

    Any thoughts would be appreciated.

    The AGM battery should not be jump started and must NOT be used to jump another car. Take it back to your dealer and have them check it out as that battery does not do much except keep the electronics going. The traction battery does all the work for keeping the car running.

    Interesting - I basically 'jump started" exactly as per the manuals instructions -everything worked fine after that. However, it seems a bit much to call the dealer every time you leave the lights on and drain the battery.

    The lights are powered off the main traction battery, not the 12v.

    The 12v is used primarily to keep the ECUs powered.

    Hi there,

    Can you please tell me how AAA jump started your vehicle? My Camry Hybrid is totally dead. You push the power and it is green but nothing goes on. No dash lights, window don't work, no radio.

    I called service (I'm in Europe) and they were going to start from the front under the hood. But the manual says to jump start it with the 12V in the trunk. So, I decided to wait.

    Can you please tell me how they jump started the car??????

    Help!!
    Thanks.

    It's me again. I had this problem before. I have been driving the car but not enough. Now, I went out and no dash lights go on. So, it must be the 12V. I read in the manual that if the battery dies, the smart key system can stop and you might not be able to open the trunk. So, I opened the trunk, in order to jump start the 12V. Is this okay, or am I causing more damage. I know we need to jum start the 12V in the trunk. There is no radio and no dash light. Also the windows don't go up.

    The dealer here told me to call road service and have them jump start it from under the hood and bring the car in. But the manual says to jump start from the 12V in the trunk.

    Please help. I don't want them to cause more damage.

    I just had my TCH jump started as my 12V went dead. I drove it to the dealer to re-charge the battery. He said maybe I needed a new 12V battery. It has been there 3 hours and the battery has now charged 40% and he told me to leave it until tomorrow.

    The 12v was jump started per the manual and everything was working fine, I just went to get the battery re-charged.

    We are in Europe and they said to import a 12V for the TCH from the states is 700E. They said maybe the battery will die again, and we should get a new one.

    Is this really necessary?????

    Advice????
  • Under the hood there is a fuse box. Take it off and look for the red square with a + sign. unlatch this and pull it up. That is where you "jump" the car. Place the positive there and the neg on the left hand side on a engine mount bolt.

    hope this helps.

    If you do not have any clue about what to do, call AAA. ;)
