What Happens if a Battery is Connected to the AC Supply?
If we connect a battery with an AC source (say 120V or 230V AC from a wall plug), It may heat up and explode with a boom having risk of serious injuries and hazardous fire. The reason is that AC supply has frequency (50Hz in UK and 60Hz in the US) i.e. the direction and magnitude of AC supply changes multiple times in a second according to the

2. Battery charge shutoff is a thing. There was a time where you could "overcharge" a battery by leaving it plugged in, but most decent electronics now disconnect the battery from the incoming power when the battery reaches 100% charge.

21.2: Electromotive Force
All such devices create a potential difference and can supply current if connected to a resistance. On the small scale, the potential difference creates an electric field that exerts force on charges, causing current. We thus use the name electromotive force, abbreviated emf. Emf is not a force at all; it is a special type of potential difference. To be precise, the electromotive force (emf

Is keeping a laptop connected to power supply harmful for its battery
For that reason, laptop manufacturers such as Toshiba, Samsung and Sony have added a power mode that limits battery charge to 50% or 80%, if the laptop is used primarily from the AC mains. For that reason, you might intentionally discharge the battery halfway and remove it, to extend its life, but the disadvantage is that it no longer functions as a UPS. A

What happens when a battery is connected together in series?
For batteries connected together in series (+ to –), the terminal voltages of each battery add together to create a total circuit voltage. The series current and amp-hour capacity is the same as that of one single battery.
What happens if a battery cell is not supplying current?
When a battery cell is open-circuited (i.e. no-load and RL = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E. When a load resistance, RL is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance RINT of the cell.
