How Do We Use A Battery Charger

It's winter and of course the battery is a little slow on the start, but if your car is standing for a while it could be worse. 


At this point you might be thinking you have a faulty battery but so many will run out and buy a new one for no reason at all. Sometimes it just needs a top up and a charge.


What you need to know about a battery is if you leave it for too long and it drops below 10,6V it is going to destroy the cells. It is imperative that you keep the charge of your battery up as much as possible so if your car stands a lot you should seriously consider getting yourself a small charger. An uncharged battery will allow the acid in the battery to become water, thus causing the cells to be unable to hold charge. If you charge it for long enough the water will turn into acid again and the more powerful the charger the better this charge will be, but one sure thing is a drive around the block is not going to resolve this. 




Most battery chargers for household use like the one above require a 48 hour time to charge as it is known as a trickle charge, but even with a charger this small you should always disconnect the battery from the vehicle and charge the battery on an insulated surface. You should always keep in mind that your battery is connected to the electrical circuits in your vehicle and some of these components can be very expensive. My point is air on the side of safety. Remove the battery caps to ensure the cells can breath especially on the stronger chargers and ensure the charging area is well ventilated as the acid is poisonous. Connect the Red to the positive side and the Black to the negative side and simply allow the battery to charge.

While you might notice that the voltage is back up past 12v very quickly this does not mean that the battery is fully charged. It needs to hold a load , the side of the battery that specifies AMPS. This is why we recommend charging for about 48 hours on a small charger. If you have an industrial charging station you will most likely have a load tester as well as hydrometer that will let you know how well charged up everything is. 

Battery check

Once done simply make sure the water levels are correct close it all up and put it back into the car. If you own a voltmeter start the car and make sure that charge is going through the battery and it is charging up as required. Also make sure it is not overcharging or you might encounter a battery explosion in your car. If all else fails purchase a new battery according to the amperage specification of your vehicle or alternator. It is important to match the amp hour charge rate to your alternator or you will struggle with alternator repairs if it cant keep up. 

Keep you battery clean and maintain it well to ensure a long life.
