Fellow programmers. of recent the power supply in my area has gone from manageable to very very bad. I have been thinking, is there any sort of external battery or inverter out there that can power my laptop for about 10 hrs straight that is not too expensive? i'v thought of using car battery but don't really know how to make it work, i have also heard about used INEC batteries but rumors has it that they die off in less than 6 months. Please anyone with idea or info should please kindly drop it here.

Thanks

Build / buy an inverter...and better stil, mount a solar panel of bout 2metre sqr on top of the circuit!!
