I am using ASUS k53e laptop that uses 19V 3.42 A. I live in a place where there is 10 hrs power cut and my laptop gives backup of only 2-3 hrs. Can I power my laptop from two lead-acid (12V) cells connected in series and regulated to produce 18 Volts?

Hi
yes that would work,just ensure that the regulator can handle that current comfortably as it will be in use for 10 hours.
Also fit an inline car type fuse as if you were to get a short those batteries can produce very high current.
