Car batteries?

So my mom is laid up, just had major surgery. Can't drive for months. We have been turning her car on and running the motor. The battery low indicator comes on every time I start it. She said she just got a new battery just over a year ago. Why would this be happening and is there something I can do to fix it or does it need a new one?
Thanks.

New battery, new car, or new mom?

Drive it down to your local auto parts store and have it tested.

Re: Car batteries?

Sounds like it may be defective (the battery, not your mom. Or maybe that's why she had surgery), or the car sensor for it may be bad. Do what Abob says, go get it checked at an auto parts store, or the place she bought the battery from. If it's bad, it'll more than likely still be under warranty and you can get it replaced for free. If the battery is good, it's the sensor, I which case you need to get the battery sensor looked at.

Re: Car batteries?

Hook the battery to a battery tender. It will keep the battery fully charged.

Re: Car batteries?

Starting the car briefly will deplete the battery faster. That's probably what you've done.

Yup. A trickle charger is your best bet. I have two cars that I probably use about once or twice a month and I use trickle chargers so the batteries won't go bad. I also replace them every five years. They tend to go bad after that.

Re: Car batteries?

So, basically your mother's car has been sitting in the driveway for months. I can guess it sat through winter - cold weather can deplete battery. I used to work at automotive distribution warehouse, the guy from Interstate told us that if we left new battery on cold cement floor can cause battery go depleted.

Re: Car batteries?

Bring it in to get it checked out. The two times I had a battery problem, one was a cheap battery in cold weather which lessened it's life and the other time the problem was with my alternator.

Re: Car batteries?

The guys at the battery store told me that driving 10 miles may not be enough to recharge what was lost from starting the car. If you are starting her car and letting it run less than 5 minutes, you are almost certainly using power faster than the battery is recharging.

Attach her car to a battery charger at the least. If she won't be using her car for several months, I would drive her car around every once in a while to keep everything lubricated. If her fuel injectors get gummed up from stale gas sitting in them, you'll need a tow truck.
