What happens if I leave my laptop charger plugged in?

There’s no danger of overcharging a battery if you leave it plugged in all the time. As soon as it hits 100 percent, it will cease charging and won’t start again until the voltage falls below a certain level. Fully discharging a battery will damage it.

Can I use a charger with higher voltage than the original?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. If it doesn’t, it may run hotter than normal, which can shorten the device’s life or cause immediate damage.

How much voltage is a laptop charger?

Most laptop chargers are rated at 19 volts. The extra voltage a charger has over a battery is so the charger can simultaneously power the laptop and charge the battery (if they had the same voltage rating the charger would only have enough power to run the laptop).

Can I use a 19V charger on a 15V laptop?

You can not however use a 15V charger on a laptop that requires 19V or vice versa. The output tip needs to match. However, to avoid any damage to your laptop it’s usually a good idea to check the polarity against that of the laptop or your original charger.

Can a laptop battery be overcharged if plugged in?

A lithium-based battery can not be overcharged even if you leave it plugged in at all times because as soon as it is fully charged (100\%), the internal circuit prevents further charging until there is a drop in the voltage. While overcharging isn’t a possibility, keeping your laptop battery discharged is an issue.

Should you run your laptop at 100\% battery charge?

Operating your laptop at high temperatures while plugged in at 100\% battery charge isn’t recommended as well. Temperatures don’t just mean the ambient temperature, but the temperature of the battery which might also be affected if your laptop is kept somewhere where heat is being trapped — such as a pillow or at a not very well ventilated spot.
