How to Charge 12V Car Battery with 19V Laptop charger | DIY Car Battery Charger

Описание: In this video you will see a very simple way how to charge a 12 volts car or a motorcycle battery with 19 Volts laptop power adapter (laptop charger)

Difference between 19 and 12 voltages drops on a light bulb, I've used 12 volts 21 watt light bulb.

If you need higher current use two 21W bulbs in pararel, or you can use just one 55W light bulb.

Important: Charging will NOT stop automatically even if battery become fully charged, so you need to disconnect charger manually when a battery reaches 14.2 volts, or when cells of the battery starts to release hydrogen.
