Why not power your own DC

With all the products out there that run on wall warts, ie 3,6,9,12,18 volts DC (lots of DA, phono amps and even some pre-amps) why don't more people run their own DC instead of using the warts or buying the manufacture's outboard battery system?

I am amazed that the manufactures outboard units can cost anywhere from $200-1000, when one can be built using lead cell batteries for $50 or so. Using the lead batteries would allow for recharging and one could also choose the amout of amps they need or would like.

```Recharging a lead/acid battery gives off hydrogen gas, Very explosive and corrosive to the lungs. Hence the ventilation reason. If you ever experienced a hydrogen gas explosion I'm sure you would never want another one close up or in a home(with a battery; acid everywhere ). Just be carefull, use common sense. Any spark will set it off.
