Default Battery

Do you people remove your battery or put it on a trickle charge during the winter storage?

I think for the most you will find that most of us use a storage charger on our cars. They are cheap and easy to use. It maintains the power to the car over storage.

Most of us hook in the plug in cable that will make it an easy hook up with one plug.

Keep an eye on battery tenders and make sure the green light is on. Had 2 go nuts last winter, over charged and killed 2 batteries.

With my C5s, I had the battery hooked up to a Deltran Battery Tender Plus - worked great.

For my C7, I use the factory CTEK branded battery tender.

I also use the Battery Tender Plus. I'm looking to get a Optima red top, you can still use this tender with it right?

My C-5 is stored in a garage that's attached to my home, and which also has other cars parked in it, therefore I try to avoid as much risk as possible. I've been using Optima batteries in my car for years, so I bought an Optima charger, and in the winter, every 3-4 weeks, I put the charger on the battery and let it run through a charge cycle.

A word to the wise on those type disconnects; This came from C&S Corvettes. They had a C5 in their shop with one of those disconnects. It had been to another Corvette shop, and a GM dealer, before it got to C&S. Nobody knew why the car would stall, and not crank over to restart. It had an intermittent voltage issue. C&S figured it out immediately. The disconnect had a thread that wasn't machined all the way to a shoulder. It bottomed out before making a good connection. So make sure when you get one of these units, it tightens up all the way to the contacts, not until it just feels like it's tight.....

I’ve never disconnected the battery with float charging - what is concern? Is it if the charger gets wacky messing up the car’s module?

That was a concern of mine when 2 tenders killed the batteries in my LS1 firebird and C4 L98, but everything was OK.
