How to Disconnect and Fix a Duramax Battery
The Duramax diesel engine is fitted in heavy duty trucks made by General Motors. The battery can be the cause of problems within the engine for a variety of reasons, and while the battery sometimes has to be replaced, you may be able to top up the battery fluid and get it working again. The battery itself is not particularly complicated, but it does contain some toxic chemicals so often it is better to purchase a replacement than attempt a repair yourself.

Park your diesel truck on level ground and open the hood. Locate the battery. In some models it is hidden under a plastic cover. Remove the plastic cover by undoing the clips. You may need to use the screwdriver to pry open the clips.
2Disconnect the black, negative terminal from the battery by loosening the nut on the clamp and pulling the clamp up and off the battery terminal. Disconnect the red positive terminal by loosening the nut holding the clamp in place and lifting the wire off the terminal.
3Remove the clamp or bar holding the battery in place by loosening both nuts. Grasp the battery with both hands, remove it from the vehicle and set it on a work bench or similar.
4On top of the battery are two rectangular covers. Pry these up with the flathead screwdriver and set them aside. They are very tight and they have acid underneath so be very caul the acid does not splash on you or anything around you. Some batteries may not have the cover in place. These are not fixable and have to be replaced.
5Pour distilled water into the battery until the acid and water completely covers the terminals. Replace the covers on top of the battery by pushing down firmly. Replace the battery in the vehicle.
6Replace the clamp or bar over the top of the battery and tighten the nuts to hold it in place. Replace the clamp over the positive (red) terminal and tighten the nut to hold it in place. Do the same with the negative (black) terminal
7Replace the plastic cover over the battery, close the hood and start the truck to make sure the battery works. If the battery was dead before you started then you may need to jump start the truck.

How to Disconnect the Battery from a 1994 Chevy S10 Pickup
Disconnecting the battery cables from the battery on your Chevy S10 pickup is necessary anytime you are working on the engine or electrical system in your truck. The cables come off very quickly and will ensure the engine cannot get accidentally started or cranked over while you are working around moving parts or parts that could become suddenly energized. If you are replacing a battery in your S10, you will need to remove the cables as well.

Open the hood of the truck and locate the battery on the passengers side of the truck. Loosen the clamp bolt on the negative battery cable end with a wrench.
2Lift the negative battery cable off the negative battery terminal and isolate the cable away from the battery. Loosen the clamp bolt on the positive battery cable end with a wrench the lift the cable off the battery.
3Isolate the positive battery cable from the battery terminals while you work. Since the cables are no longer connected to the battery, they can be secured away from the battery together with no risk.
