Check the 12 V battery voltage while operating a window or just see
how much the lights dim ...

With the car in READY? With the car ON, the 12 VDC system gets the power
from the inverter. But if you notice the speed change with the car not
READY, so you're running on just the battery, this does sound like it
might be getting a bit weak.

The battery is rated at 35 Ahr and I think AutoZone will test it for

But before doing a battery swap, you might check over in "Prius
Technical Stuff" and probably even PriusChat about how to add water.
This is not a difficult task and a little distilled water goes a long

Sounds like a good idea but not something I worry about. In my case, I
don't have much 'stored' in the ECUs.

I've heard a lot of good things about the Miata battery. But I need to
point out I live in North Alabama and our batteries suffer more from
heat than cold. So for me, a lawn tractor battery is a good alternative.

That's not a "beware" item.

Saying that a car battery went dead after 7 years is like saying "water
is wet".  Big deal.

Um, do you think paying over $35 to replace said battery is also not a
big deal?  I rather doubt he would have posted anything saying "beware"
if it had cost under $00.
