Anyone running a battery tender?

I use one on my 67 since it doesn't get driven all the time. It's a cheap investment and worth it for any car that doesn't get driven every day.

i ran mine into the wheel well so the hood can stay closed, had it on since 04 still have the original battery in it.

Run one on the 03 because it's a major garage queen.

I Just learned something...thanks

I'm sure everyone knows that rather than clamping the leads on the battery you can use the cigarette lighter adaptor on the Battery Tender and just plug it into the cigarette lighter in most cars to keep the battery fresh. No need to open the hood, I always keep the windows cracked under the car covers anyway and just run the cord out the window, under the cover and to the BT. Also, they are NOT meant to be used on the new AGM Autolite ($350) reproduction batteries used in 60s/70s cars. That manufacturer now includes a note saying to only use a 15 amp changer, and use only when the voltage drops below the threshold.

YUP!! A must have if you plan to store the car for winter or over a period of time.
I used to disconnect the battery on my Hugger Orange SS, but then later I started using a battery tender. I now use it on my Roush. It's a CTEK 3300.
It's a smart battery tender, where it charges the battery up to 80-90% life and then backs off and repeats the process. I bought an extension and the cigarette lighter outlet. Super easy. I just plug into the the 12v on the dash and you're good to go.

Its a must have.

Starting a car to charge the battery is not good for the engine. It will not create enough heat to rid of condensation in the crankcase. The procedure will NOT ruin a car after a few cycles but moisture in the engine and exhaust is bad in the long run. By the way, coolant temperature is not oil temperature.

I use a battery tender junior. Just had to buy a new one b/c the old one took a dump after a few years

Same here. I had the original for years but it quit working a while back. Replaced it with the battery tender junior. No complaints. It stays on my Cobra constantly.

I know you have a 13-14 and I have a 13 GT. In storage now with a cover. I bought the battery tender plus but haven’t used it yet. So that cigarette lighter port on the dash stays live? So just get the extension so the tender can sit outside of the car on the garage floor?

Correct

Yes.
I bought the extra extensions from CTEK to do just this. So much easier for me as I fire up the car every 2 or 3 weeks, let it idle for 20 minutes and drive up and down the driveway tp get the mechanics and tires rotating/moving.

Good info! I need one of these. I tried to start my Cobra today and it was dead as a door nail.

a must have to keep the batteries healthy

I have three battery tender junior's. Mustang, mower and 4 wheeler.

I use them on my cars as well as my R6, one great thing about having them is they are a nice fail safe after learning the hard ways. Going on travel I've had jump boxes fail and still be stuck on the side of the road waiting for a tower or something as well as running into other people stuck who've not had cables or I had none on me at the time like on my bike <was packing real light>. I forgot who makes it but I found a piggy a while back that was basically a spliced gator clamp ordeal with optional cig lighter swap to tender hookup just as a backup if they don't have a cig slot that saved my ass when riding my bike 800 miles because I got stuck in the mountains with no cell reception. Was on a still fairly used road, reach in the backpack yank the cord hook it up and get a charge from someone <the people who helped me didn't have cables on them at the time either and it was just north of San Fran going north on 101> that let me hook up to em for 15 mins with the cig adapter after my stator failed a week after replacing it. Now I just leave them on all the time because it's not like that few ounces is going to hurt the weight and its a nice safety especially if you're packing light like I did on my ride. Options along with safe is nice even if its not just for winter storage because when I got royally stuck on my bike it was 2AM and freezing along with no ability to use my heat suit and was 30~ miles from nearest town when only a few car's would pass by every 30 mins or so. I'd rather not be trapped on the side of the road at all unless its from something catastrophic like an alt dying or hucking a belt with no backup and so on, when you don't really have a choice or really really don't want to wait on some tower to take an hour or 2 just to get to you. Plug & go lifestyle 4tw.

thought about it...never used one the last 5 years of not daily driving my mustang. Same battery I've had for 8 years or so...had to replace it in college at some point. But the car gets parked for months at a time...i just usually disconnect all leads to the battery. Never had an issue. Granted the battery is usually out because I'm doing upgrades on the car every winter anyway. This will be the first winter I haven't had the car completely blown apart since getting a daily.

I have about a half dozen Deltran Battery tenders. Ive started cycling them, vs letting them run at all times on a battery. Cars that are emissions exempt, Ive started disconnecting for the winter (will still put tender on a couple times over the winter). For Lithium Ion batteries, using Ctek
