I parked my '06 C6 Coupe and forgot to plug the car into my battery tender. After a week and a half, I tried to pull the car out for a wash and noticed the battery was dead. I tried to jump the battery with one of those emergency jump starters, but there wasn't even a click upon button press. I put the car on the tender (in reconditioning mode) for several days, but still didn't get even a click upon button press. I cannot get a jump from another car due to space issues in the garage.
Some batteries don't handle deep cycle well, so it's likely the battery is toast. That has happened to me more than once.
So, the term "deep cycle" means a very low charge state?
Are there batteries that can handle low charge states?
BTY, the battery in question is a GM AC Delco from the dealer.
My guess is your battery is toast, once they fully discharge they never fully recover. I’d say, get a new battery. You could try cleaning the terminals, but I still think the batteries toast, and next time don’t forget to connect the tender.
How old is the battery?
If more than 3-4 yrs, I'd just buy a new one.
But, there are ways that might work to recharge totally discharged batterys. Check out youtube. Some tenders don't have enough power to recharge a discharged battery, only to matain. Buy actual charger??
If it went dead after 1 1/2 wks, you may have problems with your car not turning off completely, etc.
Yah, a battery in decent shape and fully charged should still start your car after a week and a half has gone by. Either the battery was nearing end of life, or you’ve got an abnormally high parasitic drain. Deep cycle batteries like those that are found in golf carts are designed to drawn right down and charged back up again over and over.

Do you think my battery is destroyed?
I agree that the battery may be toast. Some booster/jump starter devices will not boost a completely dead battery but some boosters have an over ride button to get the job done. If your booster is equipped this way at least you might be able to get it out of the garage.
If the battery is dead many chargers will not charge it without being able to detect some voltage. You can put another battery 'jumper cables' on it first to give it a kick. I always keep a spare small sealed lead acid battery handy for jumping cars anyways. Inside a jump box is just a battery sealed

I bought the battery roughly 2 or 3 years ago. The battery drain has been a problem for as long as I have owned the car. Also, this is the longest I have ever left the car off the tender.
I am heading to the dealer with battery in hand. They can recycle the old one.
Save yourself some money and forget the dealer. The batteries at the dealer are no better than any other. Go to Costco, Sams or Walmart and get a regular lead acid battery at a good price. You will be charged a deposit fee that will be refunded when you give them your old battery.
I don't believe maintainers will charge a dead battery, you need an actual battery charger. I have an ancient sears charger capable of 20 amps, and also a newer noko 10 amp that says it can resurrect batteries that have been deeply discharged. It has worked so far.
I learned after first buying my 09 that it needed a tender lol
after the battery drained i purchased a battery tender plus and it went into error after a couple minutes of being plugged in but after unplugging it and plugging it in about five time it charged enough to get above the low level state and has been fine ever since
1) I don't own a battery tender, 2) my 2012 has the OEM battery still in the car, 3) have had the car since November 2023 and it never fails to start.
The OP has a bad battery and/or something draining the battery. Batteries just don't go from charged to dead in 10 days. Also as already stated a battery tender won't charge a dead battery. My final thoughts, don't go to a dealer looking for support on an 18 year old used Chevy, that is what the FLAPS are for.
my car has a parasitic draw then as it was dead within one week, wouldn’t even open the door
and for the record the battery tender PLUS did eventually charge the battery after a bit of cycling the power to it

What's in your toolbox? When chasing down parasitic draw my go to tools are 1) Fluke Multimeter, 2) Power Probe III, 3) Tempo wire toner, 4) assorted wire leads and connectors and 5) electrical schematic. With those basic tools you can fix just about any automotive electrical issue. YouTube University is also a good source for information.
You don't have to spend big money for the above tools, some good quality off brands can be had. However, I think the Power Probe III is the only way to go for that tool.
thanks for this
i keep it plugged in now but it would be nice to know what killed the battery

It seems that my battery was not dead. But, rather the charge state was very low. The dealer put a full charge on the battery. Been using the battery for a few days with no apparent issues. When I picked up the battery, they handed me this test document.
