Charging Your Car Battery

NO, it is not necessary or even recommended to disconnect the cables from your car battery before charging.

It is however very critical that you follow all o the charger instructions for connecting the charger to your battery, AND the instructions regarding setting the charger controls [if there are controls to allow different voltage and charge rates.

The only reason I can think of for disconnecting the battery cables is if you needed to remove the battery from the vehicle [as for example to take into your garage for charging].

On a 1998 Pontiac transport what does it mean if the battery light comes on after the car has runs for a few minutes?

That indicates a charging problem, The battery light is designed to come on, if the voltage in your system falls below approx 11 volts. I would look for alternator loose wires, broken wires, and/or have the alternator tested. Be sure to disconnect the battery before doing ANY servicing. A bad voltage regulator inside the alternator could be a problem. If it were not charging the battery at all by now you would have gotten a dead battery. If the vehicle battery is also worn out or bad, you could be getting the same results, in which case you need to have your battery tested as well.


Does more current flow out of a battery than into it?

Generally the solution to these problems is don't disconnect the battery from the car. In order to change you battery you need to connect a small 12 volt battery to the terminals before you disconnect the car battery. It need not be a large battery since the drain will be minimal and the time short. A set of flashlight batteries works fine. Mercedes are particularily difficult because you loose the radio among other things if you disconnect the battery. You must get a dealer to reset it. This negates anything you save by installing your own battery. Note a battery charger also works.
