Yet, lithium-ion batteries demand careful handling during charging to

charging battery with DC power supply

If your power supply is well-regulated (with linear regulators or switched mode power supply), so that it outputs 12V at all load levels, the voltage is way too low. Common float charging voltages that can be left indefinitely on are 13.5V - 13.8V. Fast charge occurs at voltages of about 14.5V, but then you need the ability to stop the fast charge and switch to float charge

How many watts can a 19V power supply charge?

Be aware if you intend to use your laptop 19V power supply that it is only capable of providing about 64W, so this limits your 12V charging to somewhat less than this. You might only be able to provide about 50W maximum to charge the batteries, giving about 3 - 3.5A of charge current as you approach fully charged.

Can You charge a 12V battery with a 15V Charger?

You can charge a 12V battery with a 15V charger, but it is not recommended. The higher voltage will cause the battery to charge faster, but it can also damage the battery.

So, again using my own notebook charger as an example), if the supply is rated for 19V @ 4.74 or 90W (19V x 4.74A = 90.06W), it would do no harm to use a charger that was rated at 6A as long as the 19V (or slightly more) remained the same. It would just be a 114W charger now. Remember, electronics draw from their supplies what they need.

Can You charge a 12V battery with a power supply?

The short answer is yes, you can use a power supply to charge a 12V battery. However, there are some things you need to keep in mind when doing this. First, make sure that the power supply is rated for at least 12V.
