Do you have to disconnect the battery to use the charger or can you leave it connected and in the car?

Just connect it to the proper terminals even with the car's terminal connected. I've been using the charger for more than a year and it really activates my car's and motorcycle's batteries.

You can disconnect if you are going to use the car soon or else keep it plugged in so that the car continues to receive minimal current in order to maintain full charge!

No need to disconnect battery. In fact, new H-D Limited comes standard with leads attached to battery. Great product.

The manual does not mention needing to turn it off when charging is complete. Just unplug from the car and return to the plug dock. Reconnect to car to resume charging. Have had for five months and have rarely turn off.

I have never disconnected my vehicle battery during charging, Car or bike. The voltage applied from the charger ie equal to the battery so it should have no affect on the electronics. I have a BMW motorcycle and it's fully computer controlled and I keep it on the tender when I'm not riding. I have never had any issues with it being connected. I hope this helps.

the battery has to be disconnected from whatever the battery is powering, otherwise you charge not only the battery but also the connected car/RV etc. This can be harmful to your cars electronic or the charger itself. I sell these chargers (6 volt version) with my battery powered pet fountains and had no complain over many years.

I'm a mechanic and yes it will drain the battery if you leave it plugged in while the car is off, my suggestion is to hard wire it into the car with an "add a fuse" , it's simple and cheap and will turn on and off with the car without draining the battery (look up a video on YouTube "how to hardwire in a radar detector")

The car needs to have a battery that you can draw power from consistently. If you can run chargers, you can likely run this. It's connected directly to the battery, so it shouldn't be any issue. Mine is hooked from the battery, with the cord threaded under the hood through the dash area up by the steering wheel, on the farthest left side. I mounted it there, and I got a better switch for mine. In fact, mine can be run even with the car off, because batteries can power things if they are directly tapped in.

You're not supposed to leave it on the charger if it's plugged in. It will lose the battery life sooner. Only charge for four hours when needed.

There is a charging port just below the front of the seat where you plug in one end of the charger and plug the other end into the wall outlet. You do not have to unplug and remove the battery to charge it.

You can use it with the charger connected, however the charger chord is very short so you can not use it comfortably that way. Not sure how long the battery lasts.

Leaving the battery in after it's charged won't harm the charger but, it can shorten the life of the battery. Batteries need to be cycled between a full charge and discharge for a long life. A few hours won't harm anything but, I wouldn't recommend leaving it on the charger when not in use.

I am not sure about this. It would probably depend on the the specific vehicle and its electrical system. I have heard that some manufacturers recommend removing the battery when charging it. I don't know if this recommendation applies to trickle charging/maintaining (like the BatteryMinder ). To be safe I would probably remove the battery unless you find information that states otherwise. Jim

I just turn it off when I leave the car, and on when I get back in the car. It says 'connected" and you are good to go!

You can leave it unplugged but the battery last 3 or 4 hour, after that it needs to be plugged so it can charge.

Yes, you can leave it connected all of the time. It'll automatically stop charging when the battery is full. But why would you want to? The charger is always converting 110v AC house current to 12v DC battery charging current. That produces heat and wastes electricity (aka $$$). I unplug mine when the light goes green meaning the battery is charged.

I leave my battery on the charger until I get ready to use it and the battery is always fresh, the charger cuts off when the battery is charged to the best of my knowledge.......
