No , other wise the 'charge ' will go through the vehicle's electrical system as well , best to remove battery completely unless you have a big enough garage or similar , but you must disconnect the battrey leads and trickle charge for 214 hrs

SOURCE: starter location and tools needed to replace

It is located under the car toward the front of the motor by the oil filter. Look for a metal cylinder like object with a big 4 gauge wire going to it. To change the starter you will need to disconnect the battery. Using a 15mm socket and entension remove the 2 starter bolts. You may have to remove the oil filter to get enough clearance to get the starter out. Some cars have a 13 or 15mm bolt on the back of the starter for extra support. If your's has this you will need to remove it.once you pull the start down remove the 8mm and 13mm bolts that connect the wires to the starter. Be careful not to let the starter hang from the wires as they will break. Install the new one in reverse.

SOURCE: Batteries won't charge while wired to truck

Hi, seems that your alternator diodes are faulty.
You can check this by disconnecting the radio & switching off all interior lights etc.
Then remove one battery lead.
Then get an amp meter and connect it between the battery & the removed lead.
If you get a reading the alternator is drawing current , hence faulty diodes.
The alternator will still charge the battery when the engine is going but then discharges when stopped.
Also check your batteries with a hydrometer by checking the battery acid in each cell as you could have a dodgey cell in them.

I need to store my son's 2004 VW golf for a year, and can't drive it on the road. Can I disconnect the battery without triggering the burglar alarm, or do I have to keep the battery charged?

You can disconnect the battery. However I would disconnect the NEGATIVE cable, and purchase a 300 miliamp solar charger and book it up to the battery. They are inexpensive, Bout 30 - 50 $.

There is no power going to it what should i check

Check the battery. If the battery is good, check the fuses. If the fuses are good, there might be a problem with the ignition. But, let's go back to the battery. Besides checking it for a charge, you want to make certain that the terminals (battery posts) are clean and the battery cabling is not damaged. And if you charge the battery or jump it, be certain you have the cabling attached to the proper post and a ground. If you put the cable on the wrong post, get ready to buy a new battery and maybe a trip to get your electrical system fixed. It is a major cause of grief.

If the car cranks after charging the battery, there is still a question whether the alternator is working or not. If it is not, the battery will be depleted after driving. Of course, if you have a battery that will not hold a charge, it also will become depleted in short notice. But you can test a battery after putting it on a charger without even hooking it up to the car. The tester will probably show very quickly that the battery is not holding a charge, regardless how long you leave it on a charger.

Is the charger to be "on" while charging it; then on while hooked to battery?

The portable charger should NOTE be connected to a battery while the battery is connected to a vehicle! Charge the battery off the car, then disconnect the charger and put the battery into the vehicle to start it! If the charger is not working check the fuse! If that is ok then probably damaged the circuitry!

How do I charge my battery on a 2000 boxster porsche

The battery is located in the front trunk of the car, under a cover just below the middle of the windshield. Either remove the battery or disconnect the positive (Red) cable and hook up a battery charger. You can get a battery charger at sears or any auto-parts store. Get one that automatically stops when the battery is fully charged. If you have to charge it after each trip it could be that the battery needs to be replaced or that you need a new alternator.

Can I charge the battery for 2006 Buick Rendezvous, without removing it from the car, and if so, how?

By disconnection one of the battery wires...if it is a side post, you will need to go to your auto parts store and get a post that screws in so you can attach the charger cable...the reason that you don't charge with everything hooked up is because you can get a surge and damage the components in the computers.

Dead battery...was told to keep power to the engine when changing battery or it would cause problems to the gauges, etc. Is this true?

If your hooking up a battery charger you can attach it to your battery without removing anything. I would not have your engine running while your charging it cause that doesn't make sense to be using your battery and charging it at the same time. You can also remove the battery from the car if you wish to isolate the battery. be sure to remove to negative cable first otherwise you could cause a short and that could lead to all kinds of problems. Not really sure where your friends got there info but your engine already doesn't have power cause your battery is dead. your best bet is to remove the battery and charge it, then test it, then hook it back up. When you hook it back up be sure to attach the negative cable last.

Charging a battery on a 2001 Caddy sts

when charging a battery it is better that it is disconnected from the car's battery cables and even better if removed, also don't charge it if you smell a rotten egg odor, the cell(s) may be shorted and it could explode. remember red to positive, black to negative, hook the positive up first. don't overcharge the battery, 2 or 3 hours at 4-6 amps is enough charge to have it tested, if it won't charge then the battery is defective and needs to be replaced.
