Replacing your battery
Winter is coming, last thing you need is a dead battery on a cold morning. But firstly, make sure the battery needs to be replaced. You don’t want to spend time and money installing a new battery if the problem is not with the battery itself. Look for sulfate build-up in the form of a whitish or blue residue around the terminal–removing this can sometimes solve issues with a faulty battery. DO NOT TOUCH THIS POWDER WITH YOUR BARE HANDS, as it can often contain dried out sulfuric acid which will begin to corrode your skin. Also verify that the battery has been given the chance to recharge properly by driving constantly for 30 minutes (with minimal electrical usage, including the air conditioner).
Buy the correct replacement battery. Find out what kind of battery you’re replacing (Or the dimensions of your battery) and bring this, your cars make model & engine size information to a local motor parts store. This is important because vehicle batteries vary in size,and electrical capacity and you will want to purchase a battery which matches the size of the battery tray/support in your vehicle.
Set up a secure working environment – Park on a flat, level surface at a safe distance from traffic, sparks or open flames. Put on the parking brake. Don’t smoke, and make sure any smokers in proximity to the working area know not to smoke as well. Remember that electric- ity is not the only danger; batteries contain a sulfuric acid electrolyte solution, which is highly corrosive (i.e. can burn your skin) and produces a flammable gas.
Open the Bonnet.
After opening your bonnet, use the prop rod to keep it open (Most newer cars have bonnets that hold themselves up) Locate the battery – The battery should be located in an accessible part on either side of the car’s frame. The battery is a rectangular box with two cables attached to it. (Yes it is necessary to explain to some)
Identify battery terminals – Locate the positive and the negative terminals of the old car battery. The positive terminal will have a plus sign and the
(Usually 8mm or 10mm) and slide it off of the terminal. If the cables are unmarked, label them so that they don’t get mixed up (otherwise you may ruin your car’s electric system later on). It is also important that you disconnect the negative terminal socket before the positive terminal socket. Otherwise, you may short circuit the positive terminal to a grounded part of the car.
Disconnect the positive terminal.
Remove the car battery – Unfasten the battery holder and remove any screws, clamps or bars holding the battery in place. Carefully lift the battery out of the car. Remember that a battery can be heavy so if you have any back problems, get a helping hand.
Clean the terminal clamps and the battery tray. You can use a baking soda solution (yes many uses) and a wire brush. If there’s any severe corrosion, consider replace- ment by a mechanic. Otherwise, let the area dry before moving onto the next step.
Replace the battery – Place the new battery where you just took the old battery out, with the positive and negative terminals on the correct sides. Connect all the screws, clamps or bars that may hold the battery in place.
Reconnect the positive terminal – Tighten the clamps using a spanner.
Reconnect the negative terminal – Tighten the clamp with the spanner.
Close the bonnet – Shut the bonnet of your car firmly and start your car. Check that all the electronic devices are working properly.
Dispose of the used battery at a garage, auto care stores, and recycling centers. There may be a small fee for the service, but throwing the battery away as normal rubbish is not an option.
