I hope this doesn't sound like commercial spam but we sell a product from Japan which can increase the life of li-ion batteries by up to 30%. The hard thing is getting people to try it. Have a look at
www.batteryextender.co.uk. If anyone from this forum would like to try one just quote Total PDA Forums and you can have it for half price as long as you feedback to us on the results you have using it..we can't force you though.
