Unplugged car battery still lose charge?
Can a unplugged 12volt new car battery that is fully charged stored in a
garage lose its charge over a week’s time?
Only if it is bad to begin with.
Exactly. Exchange it, definitely sounds like a defect! HTH. -Jim
The battery owner says," That's impossible (unplugged battery losing charge)and won't exchange it. He stated I have a pallet of battery right there and I've never seen a new stored battery on one of these pallets ever lose its charge. Your generator is drsibibg the battery even when it's off."
Charge it up and do a load test on it.
If it fails the load test you know the battery is bad. Batteries have a date code on them. Depending on the manufacturer the code could be alphanumeric (L7=November 2017), or numerical (11/17=November 2017). If your battery isn't a big seller it may have been a year or more old when you bought it! So look at the date code to see. Wet filled batteries most certainly will discharge on the shelf over time and can be defective with a bad cell that will kill it quickly and/Or prevent it from holding a charge. I've had flights with retailers about defective batteries too. If the store manager won't help you threaten to call the store's corporate office or the battery manufacturer's corporate office. That should get results. HTH. -Jim
It shouldn't, unless there's something wrong with it.
