What happens if a battery is fully charged?

This causes several aging processes to accelerate compared with the conditions occurring with a fully charged battery: growth of dendrites, which may cause micro short circuits, and corrosion in rest periods. The higher the solubility, the faster the growth of large sulfate crystals.

What does it mean if a battery is low?

When the battery charge level is critically low, the power indicator symbol may change to red or display a warning symbol, such as an exclamation mark or a flashing battery icon. This signifies that the device’s battery is nearly depleted and requires immediate attention.

What voltage does a car battery drop when not connected?

Use the multimeter to make the measurement while the controller is connected if you can. A car battery has over 13V when not connected, yet drops to 10.5V while starting the engine. Which voltage is correct? Both. Just going to add a note. Some batteries, such as lithium ion, are pretty well modeled by the series resistance concept.

Can a battery be charged with a charger plugged in?

In general, having the charger plugged in and the battery too (if it is removeable), the battery will constantly be "charged" in the "constant voltage" mode to fight self-discharge. Many manufactures do not hard-cut the battery when the charger is connected, so the charging voltage is always applied.

Why does a battery drop voltage if it's open or closed?

When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current when the measurement is being made (so at the terminals the voltage is indeed lower).

Does a battery charger use a lot of energy?

Yes it will still consume some energy. It takes some energy to operate the charger itself. The charger will draw the most power from the power mains whilst it is in heaviest part of the charging cycle. As the battery becomes charged the line load will taper off to the idling mode.

A new battery will have much less loaded voltage drop than you have. An old, worn out, or damaged Lithium battery has a much higher internal resistance than a new battery. It is damaged if it has been fully charged for longer than a few months, if it has been discharged too low or if it has had too many charge-discharge cycles.

Is electrical energy wasted when a device is fully charged?

Yes, some energy will still be consumed. Assuming the laptop is switched off (not in sleep mode) and the battery is fully charged, it will consume very little energy (a few Watt perhaps). When in sleep mode, the laptop keeps the RAM powered so it will consume somewhat more power.

If a laptop is on a full battery while plugged in, is your ...

In fact, leaving the charger in all the time is one of the main reason how batteries die faster, since LiPo batteries degrade faster at very low or very high charged capacities and constantly applied charging voltage. Best thing to do: turn off the laptop (not standby) when not used and disconnect the charger, when the battery does not need to ...
