Possibly quite a suprising amount. Modern electronic devices need quite stable voltages. But batteries don't supply stable voltages throughout their life. So the devices have built in systems to stabilise the voltage from the variable voltage source. I suspect you could get away with using batteries from 5 to 10volts. But I wouldn't guarantee it..... 8-)))) > > > > > [Original Message] > > From: Adam Maas > > > mAh is a measure of capacity, the more you have, the longer the battery > > will last in a given application. > > > > 2500mAh is likely not possible in that form factor, to make a 7.4v > > 2500mAh battery would require a physically larger battery. > > > > -- > PDML Pentax-Discuss Mail List > PDML@pdml.net > http://pdml.net/mailman/listinfo/pdml_pdml.net > ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
