Default Battery Tender Question

Here's another one of those "dumb newbie" questions:

I have heard of several vette owners using a battery tender...should I be doing the same thing? And if so, WHY? Is there something that is draining the battery when it is parked in the garage?

I just want to have the feeling that I can have it parked in my garage for a week or two, jump in it, turn the key and go...I dont want to worry that it might not turn on. Next to not having a vette, I think that hearing the "clicking" sound of a weak battery when trying to show it to your friends is the next worse thing.

I think you answered your own question. The battery tender will keep a charge on your batttery so that over time it does not drain 100%.

I use a battery tender if the car is going to sit through the winter, but usually during the driving months I dont use it. That being said I will use it here and there if I notice that the battery is not fully charged (my battery tender tells % charged).

Thanks for your response! And yes, I am aware of what a battery tender does, but WHY do I have to use it for my vette? Of all the the vehicles I have had in the past (non-vettes), I have never had to put a battery tender on them.

I guess what I am asking is...is it just used as a precation? Or do vettes have the tendency to run the batteries low when they are parked?

Our batteries run down due to the electronics in the car.
The computer drains the battery while storing functions for radio and other settings.
Some have no problem within 2 weeks, but others do.
I plug in my tender after every drive (I only drive my Z06 about once a month), and when I turn the key, it cranks right up.
I know without the tender, it would not.

On the other hand, my '65 coupe can sit for over a month without a problem.

I believe the answer you are looking for is no, its not just a vette thing but any car with alot of electronics and computers. The issue is that alot of vettes are not driven on a daily basis so there is more battery discharge between charges. This can shorten the life of the battery and can result in a battery too weak to crank the engine if the charge has gotten too low. Thus the battery tender keeps the battery charged and at top performance, which would be a benefit to any car not driven very often, not just the vette.

Sears, or Fleet Farm, has them for about $25. Do not buy a trickle charger. Make sure it's a tender or maintainer.

Default Don't get the JR.

Get the regular battery tender. It is a little more expensive but much safer then the Jr. model. You can leave the regular hooked up for up to a year. It will reset if the electric goes out. It is pretty much fail safe as the Jr. is not.

I bought the Deltran Battery Tender Plus many moons ago. Excellent little device, worth it if you don't drive your car much.

The DELTRAN BATTERY TENDER JR. is .75 amp (which is fine for an OPTIMA). The DELTRAN BATTERY TENDER PLUS is 1.25 amp (also fine for an OPTIMA). They're fully automatic maintenance chargers to maintain a full battery charge. DELTRAN does have higher amp output chargers. They have up to 10 year warranties, which I think is outstanding.
The BATTERY TENDER JR. is a little less expensive than the BATTERY TENDER PLUS which is $59.95. You can usually find either model at a motorcycle shop.

I went to the Sears website and searched for their battery tender. Did not find it. That does not mean your local store won't have it. You can view the retail outlets from the link below. Also good information about tenders as well from their site.

If memory serves, bought mine from Batteries Plus.

I had a C5 that went at least 3 weeks without a problem,
I did get a tender for winter storage. I purchased a Schumacher<S> for $16 at Wally world. No probelmo.

Are there any issues with disconnecting the battery cables for a couple of minutes while attaching the battery tender yoke wires, such as needing to reconfigure some of the computer settings, etc?

Yes, there are some small parasitic drains on the battery when the car is just sitting. If you have any extended periods of time that you will not be driving the car, best to hook it up to something like a Battery Tender. I have one and it keeps the battery fully charged.
