Lead-acid batteries in cars work through a chemical reaction in the battery’s plates. Most lead-acid batteries contain distilled water, which reacts with the chemical makeup of the metal plates, resulting in a charge. Because car battery chargers are expected to deliver that initial charge for making the engine turn upon ignition, they need a high amount of current. When the car is running at cruising speeds, the alternator will take over in providing electricity to the car, and also charging the battery. In low RPMs, though, it’s still the battery that primarily delivers charge through the system.
Running low on battery charge can be a pain, especially if you drive an automatic vehicle. If you’re driving stick-shift, you can easily jumpstart or push-start the car as long as the battery still has a little charge. Once the car has been jumpstarted, the alternator will then do its role in supplying power and recharging the battery. Assuming the battery is still healthy, you can expect to be able to ride to the shop for a battery replacement. In some cases, batteries might just be losing capacity and can be trickle-charged to extend its service life.
However, if you drive an automatic, there’s usually no choice but to use jumper cables to start your car. And if your car is fairly new, chances are it relies heavily on electricity for even the engine’s fuel injectors to work. You would want your batteries to have adequate charge at all times. But when the hot summer and cold winter arrives, your batteries are likely to suddenly give out because of temperature changes. In these cases, a car battery charger would surely come in handy in your garage.
Buying a car battery charger can be a lifesaver. You can use it to jumpstart your car when your battery is low; or you can easily recharge and rejuvenate a near-dead battery. Here are a few tips in buying a car battery charger.
- Check what kind of battery your car or cars have. If you drive a gas-powered sedan, chances are it’s running on 12V power. If you drive a diesel-powered van or truck, it’s likely using 24V. Go for a charger that supports your battery voltage.
- A good start when making a comparison is browsing for online reviews and feedback on car battery chargers. Check out reviews at Rate It All , for example.
- Wait for sale season to begin before buying a car battery charger, so you can get significant savings. Car batteries usually fail right before winter or summer because of rapid temperature changes. You can expect stores to offer a sale on these items during fall or springtime.
- Make sure you are buying the right type of charger for your car’s batter. For best results, ask a sales representative to demonstrate how to use the charger.
Care should be taken when you are using a car battery charger. Consider that it’s an electrical equipment, and it can cause damage or malfunctions to your car if used improperly. You might also be at risk of getting electrical shocks or burns if you don’t know how to properly use your car battery charger.
You can use your car battery charger to trickle charge your battery overnight, to give it enough charge capacity. You can also uset he car battery charger to jumpstart the car, in case your battery is too weak for a proper start. Consult your manual for proper use, as different models might have different specific instructions.
