Dell's Optical Mouse Eats up Batteries 615

RRRNews The problem with rechargable AA batteries is that they are only 1.2 volts instead of the 1.5 volts for a normal aa battery. This is quite a diiference as each mouse requires 2 batteries, if you use recarcables you are only getting 2.4 volts as opposed to normal batteries 3 volts. This makes a huge difference, my Dell wireless mouse complains about the batteries being flat even after I have recharged the batteries for 15 hours. The Dell wireless keyboard on the other hand will run on the recharables for months. Quite surprisingly I can't find 1.5 volt AA recharable batteries anywhere. They all are only 1.2 volts. I don't know why these battery companies make such stupid decisions with their choices. I got caught out and bought an Energizer battery recharger with 4 batteries that cost about $60:00 Australian, the only thing that will take the batteries without complaining about them being flat is the Dell wireless keyboard. ricardo
