When charging batteries it is always a good idea to wear safety goggles. Also you should remember that while the change is slim, there is always a risk that a battery may explode when you try to charge it. Obviously before you begin, you will need to acquire a battery charger. Not all chargers are the same so you should familiarize yourself with your particular model prior to using it.

Inspect the instructions and make sure you understand how the charger works and what each button, dial or reading is used for. You can charge the battery while it is still inside the car or if it has been removed, either method is fine. First attach the positive red clamp to the positive post on the battery. Next attach the negative black clamp to the negative post on the battery. Next, you need to set the volt and amps on the charger. If you wish to slowly trickle charge the battery, you want it set to a lower amperage than if quickly trying to start your car.

Trickle charging is the better method to use if you have time, as it will do a better job charging your battery. However, if you are quickly trying to start the car, you will want to use a higher amperage. Plug in the charger and let it do its work. You may be able to set an amount of time for the charger to work, or it may shut off automatically when it is done.

Either way it is a good idea not to move the charger or play with the cord during this process.

When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again.

How to Use a Car Battery Charger

Read the specifications for your battery. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging. Read the specifications for your battery charger. There will be a manual with your battery charger that provides details for the appropriate use of the charger.

Choose a well-ventilated work area. Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times. Put on protective gear. Glasses, gloves, and other protective gear is a good precaution.

Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail. Once the hydrogen is in contact with the oxygen in the air, it is highly flammable and can be ignited even by static electricity. Turn off all vehicle accessories.

These accessories draw power from the battery and should be turned off before removing or charging the battery. Most batteries will be found either under the hood of the vehicle or in the trunk.

When and How to Use a Trickle Charger

It is also possible that your battery may be under the rear seat, and sometimes the battery can only be accessed from underneath the side of the car. Identify the positive and grounded posts on your battery. There are a few ways to tell which is which: Compare the diameters of the battery posts. For most batteries, the positive post is thicker than the negative post. If the battery cables are connected to the posts, note the color of the cables. The cable connected to the positive post should be red, while the cable connected to the negative post should be black.

Disconnect the vehicle battery cables. Disconnect the grounded terminal negative , then the ungrounded terminal positive before removing the battery. Remove the battery from the vehicle. Some vehicles require that you remove the battery before charging, others do not. You can charge the battery inside the boat only if you have a charger and other equipment that is specifically meant for doing so.

This will avoid putting pressure on the battery ends and forcing battery acid out of the vent caps, as might happen if you carry it in your hands. Clean the battery terminals. Use a mixture of baking soda and water to clean any corrosion off the terminals and neutralize any sulfuric acid that may have spilled on them.

You can apply the mixture with an old toothbrush. Alternatively, you can clean off mild corrosion by using a wire brush. Auto parts stores even sell a special round wire brush that fits over the terminals. Do not touch your eyes, nose, or mouth right after cleaning the terminals. Wash your hands immediately.

Do not touch any white gunk that may appear on the terminals, as this is congealed sulfuric acid. Pour in enough distilled water to reach the fill level on each battery cell. Pouring water into your battery cells disperses hydrogen gas from the cell. Do not use tap water as it will damage your battery over time. If your battery does not have flame-arresting caps, put a wet cloth across the top of the caps.

Place the charger as far from the battery as its cables will allow. This will reduce the possibility of damage to the unit from any airborne sulfuric acid vapor. Never place the charger directly above or below the battery. Set the charger to deliver the correct voltage. This is done by adjusting the voltage output selector, usually on the front of the charging unit. If your charger has an adjustable rate of charge you should start at the lowest rate. Connect one charger clip to the positive post on the battery. This step is the same whether the battery is removed from the vehicle for charging or not.

Connect the second charger clip to ground. There are two different cases for connecting the ground. This prevents arcing at the battery terminal and will not run the risk of causing the battery to explode. Clipping the grounding cable directly to the negative battery terminal can be dangerous. If the battery has been removed from the vehicle, you should connect a jumper cable or insulated battery cable at least 24 inches 60 cm long to the grounded post.

Then, connect the battery charger clip for the grounded post to this cable. This allows you to be away from the battery when you complete the circuit in case it explodes. It is also a good idea not to be facing the battery when you connect the charger to the jumper cable. Plug the charger into an outlet. The charger should be equipped with a grounded plug three pronged plug and should be plugged into a properly grounded outlet three prong outlet. An adapter should not be used. Use an extension cord only if absolutely necessary.

If an extension cord is necessary, it should be a grounded three pronged extension cord and be the proper wire size to accommodate the amperage of the charger.
