The pressing need for more renewable, greener energy has certainly put rechargeable batteries on center stage. But what do we do if we are away from home, and our starter or smartphone battery runs flat? At moments like these it pays to know how to choose the right battery charger from what’s available.
Our utilities supply alternating current, because that’s what we get when we generate it. Electrochemical batteries, on the other hand store potential direct current. That’s why we need inverters for our uninterruptible power systems. By the same token, we need battery chargers to replenish our batteries from the grid.
Choosing the Right Battery Charger for Your Device
However, we don’t just need any old alternating current. We need one that delivers the right voltage, and current for our particular battery. For if we don’t, we could end up damaging the battery and even causing an explosion. This is why it is important to know how to choose the right battery charger, and why we wrote this post.
One: Confirm Suitability of Input Voltage
Voltage is the pressure with which charged electrons flow through a circuit. If the pressure is too high, we could damage the circuits in a device. If the voltage is too low the device cannot perform. This is why voltage is important. Make sure the voltage from your utility is within the charger’s range.
TWO: Choose a Battery Compatible Charger
Any old smartphone charger will not necessarily do. This is why you should compare battery types before borrowing a phone charger. A decent battery charger for larger appliances should be able to switch between lead-acid and lithium-ion storage batteries. However, please do read the small print before confirming your purchase. It is always better to be safer than sorry.
Can You Adjust the Charging Voltage, Current, and Time?
Chargers for small device like hand tools, and smartphones come preset for their particular device, and are not universal. If you own a bench-type battery charger, you can adjust the settings for various devices. Always read the instructions carefully before choosing the right battery charger, and remember to use it in a well-ventilated place.
