Re: Reg - rechargeable batteries
** Groper alert !
** Measure how much energy your TV and music system consumes in 2 hours -
get the answer in Watt /hours.
The battery capacity in Watt-hours = amp-hour rating times the average
voltage - this figure will have to be a little more.
Expect the answer to be about 400 Watt-hours
This capacity will cost a fortune with Lithium cells.
Think SLA or deep cycle well cell batteries.
