# Can I Use 19v Charger For 12v?

## Can I use 19v charger for 12v battery?

NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply.

You need a battery charger.

Putting two batteries in parallel does not change the voltage required to charge them it simply increases the current capability (increased Ah rating)..

## Can I charge a 12v battery with a 18v charger?

Why would you use an 18V charger for a 12V battery. It seems to me this would be too much voltage. To charge a 12V battery, you need at least 14V. … But at just 5W (which is 0.28amps at 18V) it really doesn’t output enough power to hurt a big car battery.

## Can I use a charger with higher voltage?

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, then it may run hotter than normal, which can shorten the life of the device or cause immediate damage.

## Can you charge a 16v battery with a 12v charger?

6 Answers. Your 12v adapter would only be able to raise the battery voltage to 12v, but to charge a car battery fully you would need to raise the voltage to 13.8v. The 16v adapter would raise the voltage too high and could cause damage.

## What happens if you charge a 12 volt battery with 24 volts?

Yes, if you regulate the voltage down to the right amount. If you just plug a 12 volt a battery into a 24 volt charger it will die in a matter of hours.

## Will a 19v TV work on 12v?

will 19v tv work on 12v? nope, it won’t work.

## Can I charge 12v battery with 15v charger?

So alternator voltages and car battery chargers voltages can go over 15V safely, as long as the battery is monitored to make sure that it isn’t overcharged. These higher voltages allow the battery to be charged faster.

## What is the maximum voltage to charge a 12v battery?

Although a battery is called a ’12 volt’ battery, its voltage varies from about 12.6 volts down to 10 volts when it is discharging and can rise to 15 or 16 volts during charging. It is very important, however, to limit the maximum battery voltage during charging otherwise the battery will be damaged.

## Can I charge a 12v battery with a 14v charger?

Obviously it is safe to charge a 12V battery with a 13V charger. … So you definitely need a charger having more than 13.2V. So I prefer using a 14V charger to charge a 12V battery. You can also use a boost converter with the 13V charger to increase the output voltage from 13V to 14V.
