Homemade Battery Replacement for H/P Laptop
I have a very new H/P 'Envy' laptop that I use purely for entertainment. I mean like in the Summer sitting out under my Maple tree, watching a movie DVD or SKYPE-ing with family or old shipmates. The rest of the time it is stowed away, battery removed. I have an electronic background and I know rechargeable batteries both lose charge capacity, AND simply go down sitting on the shelf. I note the 'V104' battery pack for this L/T goes for almost $50. I also see it is rated at 14.8 volts; a little odd for a four (4) cell total, but Lithium Ion batteries are not 'old hat' to me.
That said, when this pack begins to not even do a Movie DVD, I'm giving serious thought to taking my Dremel tool out, carving open the battery pack, removing the old cells, wiring and taping ten (10) Garden Variety Duracell AA batteries together and running that. Ten AA's is a tad over 15 VDC, open circuit.
Has anybody here ever done this? Ten AA's is $3.75 from Costco; one helluva lot better than Amazon !!
