Does the battery need to be disconnected from the vehicle (car, boat, garden tractor or four wheeler) before connecting the battery tender?

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

The first time you install the harness with plug end, and after that, it just plugs into that harness

No. Leave it hooked up, just hook up the tender to the pos and neg posts of the battery and plug the tender into 120VAC.

I don't know as I don't have a battery tender. If I recall, once I put the fluid in to activate it, it hardly any time at all to crank after it being on a standard battery charger.

Yes, but not overnight. If left connected for weeks or months it will. That is why it is on the battery tender quick connect plug. You unplug this device and plug in your battery tender to keep the battery fully charged and ready to go while it is in storage. If you don't have a battery tender, you probably don't have the connector that this plugs into, thus you probably shouldn't be getting this.

This product is an extension cord that connects between the battery tender charger and the connector to your battery. You only need one if the connector is too short or if you need to relocate the battery tender farther away from the car. I highly recommend the battery tender as a trickle charger. I have used mine for the last 10 years and my battery stays charged even in the winter months.

Yes, you can disconnect the battery. In fact, you have to disconnect the battery when you keep it for charging. Disconnecting battery is very simple.

No, you can keep it connected while you use the battery system of your trailer. I believe that is what you are asking. But if you mean should it be disconnected while the trailer is moving I would say, yes.

They give you a connector kit to put to the battery of your lawn tractor or ATV. Honestly, it was a very crappy connector, so I went to a auto parts store and bought a better connector and spliced it in.

I have had the same experience. I have found that if I unplugged the battery tender from the power outlet and then plugged it back in it would recycle and perform as intended. Have you attempted to start your vehicle? I'm sure your battery is up to snuff. The other aspect is that this is not a battery charger in the common term. It is a battery tender and will cycle in and out. The purpose is to maintain the battery at optimum charge without overcharging. I keep four vehicles that I don't use often on these tenders constantly and have never had a problem with my batteries. Great piece of equipment. I have had the same experience.

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.

You can leave the battery in your vehicle still connected to your battery cables; however, I bought two of these chargers, and they both died within a year. I bought Schumacher PS-1562A DSR ProSeries 1.5 Amp 6/12 Volt Automatic Battery Charger/Maintainer , and have used it many more times than the Tender model, and have had NO problems with it. It automatically detects whether the battery you hook it to is 6 or 12 volts- no need to do that yourself on a switch selector. Go with the Schumacher!

I personally do not. The supplied quick disconnect cord was plenty long enough to reach my battery. There is no need for a circuit breaker in my opinion as mine has a built in breaker right on the unit itself.

You probably could but why would you want to? Because the BatteryMinder has some pretty sensitive electronics to monitor the battery charge level and temperature, I would not recommend leaving it attached to the battery when you start the vehical... at least I wouldn't do that.

disconnect before doing any "welding"; make sure when you charge battery is hooked up correctly - red to hot, black to ground. this is a "pig-tail" that you put on a Motorcycle, Garden Tractor, Snow Blower...that sits for quite awhile each year, then can plug "battery - minder - charger in - prior to use" to "top off" or "maintain" charge during the winter....

No. I use one for a tractor battery over the winter, 2-3 months between starts. Go for it. Maybe the battery will still be some good when you're able to get the boat in the water. Better, much better to keep battery up than to let it discharge too low. That kills batteries' life span. Especially in the cold.

No it doesn't. Your vehicle needs to be running to charge the battery. You may use it with your vehicle off but not for too long

You don't leave it in the vehicle. After you are done programming your vehicle, you unplug it.

It does not, it comes with an alligator clamp set, and a semi permanent quick disconnect set that you could leave bolted on your battery terminals.
