Battery tender ?

Battery tender ?
I lost the directions to my old battery tender so I was wondering do I have to unhook the car terminals to the battery or can I just leave it connected and conect the tender right to each battery terminal? Is that a big no-no?

I always connect my charger before powering it up, so no chance of a spark.
Electrically the terminal and chassis are the same point. It is a negative ground system.

I bought the additional cigarette plug n' play and just do it that way. Way easier in my opinion.
Good luck.

I have one of those on my BMW charger, it is easier. A little more of a pain to run the wire under the cover, though. But, I don't have to get to the battery so it's a good trade off.

Just following up on earlier comments. When jumping a car, the jumper cable will have a live voltage on it and it will spark when you connect it to the battery - thus the potential for explosion if the battery is out gassing. With a battery tender, they should be connected with the tender off - so no voltage and no potential for a spark. Then plug in/turn on to charge. So it is OK to connect it at the batter terminals

This is the one I use Mark.
If you want the cigarette plug and play, you have to buy that seperately. I also bought the extension to make sure it will reach into the car.

About the cigarette charger (AKA, power port) version - I think this is not compatible with all cars. A lot of new cars disconnect power from the power port when the car is off (it appears to be on a relay). I know our Focus disconnects, but the Mustang seems to be OK.

Yes. I know it works perfect for the Mustang because this is my second year using it with the cigarette plug in. I also made sure it would work properly before being this specific brand of "smart charger".

I have my battery tender hooked up to the terminals and keep the battery hooked up to the car. I have it this way on a total of four vehicles and one ATV. On the ATV and the Ford vehicles, I leave the quick connect connectors on the battery clamps because they have bolt on assemblies I can hook the eyelets to. On the Chevy trucks, I use the clamps.
