Suggestions for Battery Tender

So, for best results, it is best to use a Battery Tender (or the like) to keep the sulfate from being able to form in the first place.

Just sayin...

I googled and found lots of web sites trying to sell me Battery Tenders

If you make sure your battery is charged (over 80%) before disconnecting negative cable, Sulfation is minimized.
My batteries last over 4-5 years and longer with no issues. And they fire the LT5 right up when reconnected.
I have noticed no other issues and that is why I am trying a disconnect switch setting aside the 5/16 ratchet box wrench.
That disconnect switch is also kind of handy when working on any electrical issues on the ZR1 so it has a dual purpose.

I am also just saying

Don't forget that the Corvette Museum sells Battery Tenders. I recommend that if you are planning to buy one, get it there. Maybe a little more expensive than AutoZone but supporting a great institution. I bought mine there several years ago.--Bob

Yep! That's where I picked mine up at the Gathering 2013

If you want the cadillac of fully automatic battery trickle chargers, get an Interacter. They are made in Connecticut. http://interacter.com/about-us/

Everything else is made in China now.

I have been using an Auto Meter one for close to 20 years without any issues

Question for Battery Tender Plus use???

Just want to make sure I hook this up correctly. Received mine the other day, and would like to know if the correct way is to hook up "P" clip to the positive terminal and the "N" clip to a metal ground instead of the negative terminal. Then, again if I disconnect both terminals and install my "dummy" attachments, I can then hook up to the battery directly???
Just don't want mess up the electrical system on our engine.....
Thanks.........

The BT clips I'm familiar with have a red (positive) and a black (negative) grips on the clips, or on the battery terminal connectors; whichever you choose.

As for the negative connection, because our cars are negative grounded, you can fasten the negative connection to the (-) battery terminal (preferred) or to the frame or engine block - whatever.

If otherwise unmarked, by measuring the DC voltage on the charger clips or whatever, if the DC voltage reading is (+), then the red lead on the meter is connected to the (+) charger lead. Otherwise the opposite is true.

IIRC, the BT is protected against accidentally crossing the leads up (with a diode). And, it has been a while, but I believe in the operating instructions it explains what the indication is, should you cross the leads up.

Battery Tender (or their equivalent) are the best thing to happen to seasonal machinery; Vettes, motorcycles, boats, lawn mowers, etc. (next to "ONE BITE" spread around the garage to keep mice at bay!!

Thanks for the reply Paul, although the instructions recommend hooking up the "N" clip to a ground as opposed to the "N" terminal itself, just wanted to make sure I get it right with this unit.
Having had and still have my over 30 year old trickle charge, which works great. You always had to unplug the plug from the alternator or disconnect the terminals from the battery itself before using it, otherwise you would have electrical complications.
But technology have come a long way since then........

Thanks Phil for the info, everything worked out fine....

Done deal!!! took 11 hours for the ZR-1 battery to fully charge, I am in the green now. Just have to decide if I want to leave it connected during the week as I keep the Z covered in the garage. Or maybe just hook it up during the weekends...... Decisions, decisions......

All in all, very happy with the BTP, works great, a good purchase....
and good info in this thread...........
