2001 CR-V Electrical Problem

The other day the car started fine, we drove about 20 minutes, and then
electrical devices started failing: first the speedometer, then the air
conditioner fan, the windows were slow, and after another 15 minutes
the car died (while driving on the highway) and the battery was too low
to start. There had been no previous problems.

The dealership is telling me we need a new battery, but there's no
problem with the electrical system or alternator. Is this possible?

thanks in advance,

If your battery is bad it may not take a charge and will not be able to
deliver current to run the car's devices.
If they've tested the charging (alternator) and it was found good, I'd
follow their advice. Get one at autozone and call it a day.

Don't run around like this: running with a bad battery can actually do
damage to electrical systems in your car.

You didn't mention the alternator drive belt. They must have replaced
it, since that's the symptoms you've described. A new battery on an '01
is probably justified too.

Ah, good point, I wish I'd thought of that and checked/marked the belt.
Thanks for your help, guys.

I am confused as I was under the impression that they'd checked the
charging system of your car. The alternator and belt would include
that.

If they have not, check the voltage across the battery with the engine
running - it should be 14.5V or so.
If you see less, check the belt and connections to the alternator. It
could still be your alternator.

The car is under warranty so they could have fixed the alternator belt
(which they would have had to anyway) without saying anything about it
and told us we needed a battery just to sell us something. Anyway,
it's done and the car's working fine.
