Laptop Battery Charging Learning Question...
Does anyone here have actual experience with the internal circuitry of a laptop with regard to bucking voltage from an AC brick?
For instance this laptop utilizes a 19.0 volt 4.0 ampere brick.
I would love to assemble a 10 ampere hour nickle metal hydride "19 volt" battery pack for it.
But NiMH batteries have a definite voltage span from full charge to needs-to-be-recharged.
At 1.2 volts per cell it takes in theory 16 batteries in series to get more-or-less 19 volts.
No car - no wall socket available. Tapping into a Wi-Fi modem.
