Leisure Batteries

[Spanky855]

Hi All

Just reading through some old threads and cannot find any recent information on this.
Are you guys and girls still using Leisure Batteries for when there is no AC power available or is there another alternative.
In my day (30 Years Ago) we always used old 12v car batteries or leisure batteries but having recently come back onto the scene and being blown away by RC car batter technology are we still using Leisure Batteries to charge this new technology ??

Many Thanks Lee
