I want to power a laptop on supercapacitors. How would i do it with 2.5-2.7 v caps? what capacitance will i need? Answered
battery: 10.8 v, 47 whr
the charger says 18.5 v output, 3.5 A
Laptop: Presario f500, Turion 64 Mk-36 2.0 ghz (800 mhz or less for most tasks) 2 gb ram, 100 gb hdd, ubuntu 9.10. i think its supposed to last aroun 2 1/2 hours on a charge, but the battery's really old so I can't know for certain. i want to switch to capacitors so i don't have to buy a new battery every couple of years.
