Default Battery Tender Problem

After plugging in the tender to my C5, the solid red light comes on and stays on NO MATTER how long I leave it on. Even 24 hours! If I unplug the cord and instantly plug it in again the light instantly goes to a solid green! I am afraid to leave it plugged in with the red light on all the time ! Suggestions?

Spend the $60 and get a new tender.

If you cannot get it to work and decide to buy a new one, don't spend $60. I bought mine new off of ebay for about $15 and a couple bucks for shipping. You can also pick them up at Wal-mart or AutoZone for $25 or $30. Sorry, but I have no idea how to fix one.

Spend $13-15 at Harbour Freight and get a float charger.

Sounds like a problem with the tender. If new, return it and get an exchange or refund. If old, I'd recommend a Sears DieHard Battery maintainer. About $30 at a Sears store near you.

on a side note, why do some people take the battery out of car, doesn't that mess up computer? I have mine hooked up to a trickle charger with battery in car, it charged for first night and has been on green light since. It has been put away for about a month now. I was just standing in garage looking at cover for 10min. It's going to be a long winter.

I am a new forum member. I bought my 2004 corvette in January of 2004. I have a battery tender on my car and it is positioned beside the battery. Number one I was told they only put out about 1 1/2 volts so it should not hurt the battery. I also noticed if I open the hood to check if it is charging, and the under hood light comes on, the red light on the batery tender will come on. If I open the hood just slightly, and the hood light is off, the battery tender light stays off.

I was also told, due to the fact they only put out 1 1/2 volts, if your battery is down it could take days for it to come up to full charge.

One and one half amps, not volts!

Cheers!

According to the instructions, the Battery Tender Plus charges at a rate of approximately 1 Amp Hour per hour. The instructions go on to say, "Some Large Automotive Type batteries may take up to three days or more to fully charge."

Make sure your connections are correct and solid. Also try it on another vehicle and see what happens.

I've got two of them and they both work GREAT!
