I bought a second-hand, cheap laptop but it doesn't have a battery. It's an HP Compaq Presario V6000 series. I don't want to spend on getting a new battery right now. Is there a way I can make a cheap laptop battery out of Ni-Mh cells that I already have?
Or, if I get a cheap China made battery in the near future, is there a way to charge that Li-ion battery using the Ni-Mh cells, when it goes low and there's no electricity?
Please advise if something like this exists or if someone already made it.
