6 Frequently Asked Questions about “Can I plug in the power supply while the battery is charging ”

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.

Can a laptop battery be plugged in?

Once a laptop battery is fully charged and the laptop is used while plugged in, the battery is usually bypassed for power consumption, meaning the laptop runs directly on power from the wall outlet. This means it should not harm the battery directly in terms of charge cycles. Some computer manufactures also provide smart charging options.

Should you unplug a laptop battery when fully charged?

However, you should NOT unplug the battery when fully charged. Every time you unplug the power and use it on battery, you degrade the battery; they are only good for a finite number of charges. In addition, if you use it on battery at your desk, and then need to go portable, you might not have much use time left.

What happens if a battery adapter is plugged in?

I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.
