Does battery need to be removed from vehicle or disconnected in order to be tested?

No you don't have to disconnect any thing. Just hook up positive to positive and negative to negative the meter will read how battery showing the amount of charge it has. Then press the button and hold this will tell you if the battery will hold up to starting mode. When you use the tester the first time don't be alarmed as it will start smoking. This is just the newness of the heating element putting a draw on your battery . after that it won't smoke any more. Hope this helps. I really like mine.

I've tested batteries both ways and it works fine for me.Just read the owners manual that is included with the unit for full instructions on the proper testing procedures . And all safety instructions.

It does not need to be removed but I do recommend disconnecting it for an accurate test

No. It works while still in the vehicle. I used it on my lawn mower and jet ski and it works well.

No its better to leave it in so it will be ready to roll when unfolded. You never need to unplug the battery.

NO. The power supply is not interrupted. If your vehicle port charges when it is off, you should be fine. But also consider that leaving it for extended times can drain your battery.

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.

I will try my best to help you with your question. First the batteries need to be fully charged overnight. Next they should not be connected to any equipment in any way including ground. Next follow all the instructions for the testing procedure. When doing the test which is a very short time period as indicated in the instructions you will get the reading on the meter and it will change the longer you keep the load switch engaged, it will also get hot in the tester and smell also. This is normal as the tester is putting a 100 amp load on the battery and determines how long the battery can maintain its voltage. This is why you should not hold the load switch longer than the specified time. Use a watch to time the length of time that you keep the load switch pressed and keep an eye on the meter reading. If you have followed all the instructions to the letter and you still get a low reading I would take the new battery to a place like NAPA or Auto Zone and have it tested there. That way you will know if the tester is at fault. It is a pretty simple device and there is not much to go wrong with it. Just be careful handling the meter just after testing and hold it by the handle until it cools down. The other answers you received are spot on correct. " Slightly weak" does not give any of us the whole picture of the test being performed also it is highly unusual to find a new battery that is weak once it has been fully charged and put into service. Good luck. Harold

You must insert the Red Pin with the round top into the small hole on the front of the system. If you look at the front of the device you will see it next to the red battery test button.

Unplugging is not necessary. It will, however, stay "on" after you turn off the engine and thus provide a small drain on the car battery. To avoid that, don't forget to press the blue button to turn ithe unit "off" every time you finish using it

Under the scale you should see a plastic pull tab, pull it out. It separates the battery from the battery terminal, thus keeping your scale from turning on and arriving at your home with a dead battery.

Any auto parts store should be able to test the battery.as far as the wires, do you know any auto mechanics? Lots of them own tools for testing connections and such. You could start there.

Yes. A single AA. I'm also a little paranoid about this thing draining that battery, so I usually keep a little piece of paper between the contact and the battery until I need to use it. Would suck to not be able to test battery life if the battery in the battery tester is drained.

Yes, the remote is tested before shipment. However, weather conditions CAN alter the life of a battery. It's always recommended to put in a new battery upon arrival.

With a fully charged new battery that would be the expected process. You can have the battery tested at Sears, Bell Tire, and other places usually for free to confirm all is OK. Or, you can get a 12v battery tester for about $10-20 here on Amazon that will read voltage, and other basic battery and alternator checks. I found one at Meijers the other day. You can check the battery every couple months like you would tire pressure and such. And confirm pre-winter readiness, of course! Good Luck!

Just to be safe, I'd also unplug it from the car. The unit has a cigarette plug, or direct to battery clips. I'm not sure why one would disconnect the electric.

Should be able to test 6 volt battery one at a time, not all connected together.

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

This battery is used for testing the unit when in the package. It is not needed for normal use.
