Battery Tender?
Snow on ground already...looks like it is going to be a long winter. 
Never used a battery tender before...which one does anyone recommend? Price?
I always drove the car through the winter, but with this early snow, don't think it will be an option for a little while (more snow on way tomorrow).

There are two type of battery tender. The first one, including solar system, does not stop when battery is full. Since the C5 drains less than 30 milliamps, this type of charger can over charge the battery. I recommend a battery tender that stops when battery is full and automatically restart when required.

There are a lot of these things on the market right now and some of them are very cheap. Some are cheap for a good reason… they're nothing but a small battery charger. If cheap is your goal, this is the way to go, but you owe it to yourself to verify the features of the unit.
The following are things you should look for and expect in a charger you will be leaving connected and unattended for extended periods of time. If it isn't in the writing, it probably isn't there and might explain the cheaper price.
1. Charger/Maintainer - it charges the battery and turns itself off when the battery reaches full charge, monitors the voltage and turns itself back on if the battery drops below a certain level.
2. Conditioner - desulphates the battery…
"Every element known to man has a magnetic moment at a resonant frequency ie, a point at which the chemical bonds that hold the molecules together to form a crystal can be broken. Sulphation, the number one cause of early battery failure, is simply crystals of lead sulphate (PbSO4) which have formed on the lead storage plates in a lead-acid type battery.
When a battery is used over time, improperly charged (over/under) or allowed to self discharge (as occurs during storage/non-use), these crystals build up on the battery's storage plates. This prevents the battery from ever again being fully charged and able to deliver their full power/capacity. "
3. It should also be polarity, short circuit and temperature protected.
The bottom line is you can get all of these features for less than $50, and the safety of your vehicle and home as well as peace of mind, ought to be worth that much. Deltran and BatteryMINDer are just two that have these features.
By the way, never charge a frozen battery or one that is over 120 degrees F.
Good luck with your decision… GUSTO

By the way, the Solar Charger does come in handy for keeping a battery charged without running power to the vehicle, I have one for that purpose. But alas they don't desulfate either. As I mentioned earlier, you can get all the features I listed for under $50 (~$39.99)... but not in a $10 one.

What he is discussing in this thread appears to not be the ability to de-sulphate, but to ensure the battery does not sulphate during storage by keeping battery voltage proper and constant during storage without continuous charging....big difference.
Fleet Farm sell maintainers for $20-25. They work great. I've never had a battery failure, either on my boats, or C5, and those batteries are placed on these every winter, all winter.

I've got 2 myself. Harbor Freight had them on sale last week for an amazing low price of $5. These are floaters and do shut off.

Just ordered two at Battery mart 29 ea and 6 bucks shipping. I wouldn't go for a 5 dollar charger as the store needs to make money on it and the manufacturer does so what is the actual cost 2 bucks. Deltran has 5 year warranty also. Pep Boys was 40 bucks

http://www.batterymart.com/battery.mv?p=DEL-021-0128
... it's $43.95
The Battery MINDer that has the desulphation capability is this one...
http://www.batterymart.com/battery.mv?p=VDC-12112
... it's $39.90... it's the one I have.
Deltran makes a good Charger/Maintainer regardless.
Good luck... GUSTO
