What Should a Battery Charger Read When Fully Charged?
Now, we’re going to tackle the mystery of what happens to your battery charger when the battery is finally full.
You plug in your phone before bed, exhausted from a long day of scrolling through social media and streaming videos. As you drift off to sleep, you can almost hear the electricity flowing into your phone’s battery. But what happens when the battery is finally full? Does the charger just keep pumping electricity into it, or does it know to stop?
Battery Charger Behavior
When you connect a battery charger to a battery, the charger will initially apply a high voltage to the battery in order to quickly charge it. As the battery charges, the voltage will gradually decrease. Once the battery is fully charged, the charger will switch to a “float” mode, where it will maintain a low voltage on the battery in order to keep it topped off.
The float voltage is typically around 13.6 volts for a 12-volt battery. This voltage is high enough to keep the battery charged, but it is not high enough to damage the battery.
How to Tell When a Battery is Fully Charged
There are a few ways to tell when a battery is fully charged.
Another way to tell if a battery is fully charged is to measure the voltage across the battery terminals. A fully charged battery will have a voltage of around 12.6 volts.
Tips for Charging Batteries
Here are a few tips for charging batteries:
- Use the correct charger. Not all chargers are created equal. Make sure to use a charger that is specifically designed for the type of battery you are charging.
- Don’t overcharge batteries. Overcharging batteries can damage them. Only charge batteries until they are full, and then disconnect the charger.
- Store batteries in a cool, dry place. Batteries will discharge more quickly if they are stored in a hot or humid environment.
- Don’t let batteries completely discharge. Completely discharging batteries can damage them. If a battery is completely discharged, recharge it as soon as possible.
