What do you want recharged?

Sorry, I guess I am half asleep from time change.

Returned from 10 day vacation to find that my wife's '07 is dead. The dealer recommends we try an overnight trickle charge and I was hoping for any suggestioins.

FYI, the '07 had not been driven for about 12 days and we did leave the remote sensing unit on. On the other hand, the car we left at the airport, my '05 Prius, did fine after 10 days or so and the remote sensing unit was left on on that car as well. Lesson learned.

Thanks for any help.

Jump it or put a small charger on the jumper terminals. You should be able to start almost immediately, since the 12V system only needs to boot the computers and close the HV relay. Leave it on for a bit after that, or go for a drive, and all should be good.

It takes a short 35 Amp pulse to get to "Ready". Once there the HV "traction battery" will recharge the 12V one as well as start the engine. I recommend jumping from a car without its' engine running. No sense having the two charging systems argue. Even better is one of those portable jumping units, if you can find one quickly. They cost around $40.

Jump terminals are under the hood in the fuse box (close to windshield on left side of engine compartment). The positive terminal is under the swing-away red plastic cover. Use the bolt just above it on the firewall for the negative.

I'm surprised the battery drained so quickly. Perhaps there was a light left on? New car not driven very far? It takes about 2-4 hours to fully recharge a discharged battery, due to the low current the system uses (to protect the battery). If you have a low current good quality charger you can do it yourself from the jump terminals. Don't leave it discharged for a long period of time. It will quickly deteriorate in that condition, and you will need a new battery (and they are not cheap!).

I don't mean to be dissagreeable, but the bunny has TWO pancakes on his head!

Yeah but he doesn't know that.

Actually, Oolong the bunny is no longer with part of this world. But thanks to many pictures and the internet, his spirit lives on.

I think he should be the mascot for Fred's House of Pancakes.

Thanks for the info. A lot better than digging out the back to get to the battery. In any event the slow charge worked. I assume the slow charge is necessary because the battery is a 3.8 amp battery.

Not only is he the mascot, but FHOP is named for him. I grew curious about why the heck they'd call it FHOP in my early days here and started a post about it:
