I am attempting to make a pair of battery powered heated gloves, as my hands get extremely cold in the winter. I purchased some 30 AWG Teflon coated stranded Hook up wire from Newark Electronics, was told that the wire has a resistance of 93 Ohms/1000'. I am using 2-1.2 volt 2500 maH Enercell rechargeable batteries, inside a Radio shack battery box, with a slider switch. I am using approximately 2-3' of this wire in each glove. I have only made one glove yet, but I'm having issues.
The glove has a high heat for approximately 25 minutes, and then the batteries are either drained and no more heat output.
The more important issue is that the batteries get very warm, one of the shrinkwrap labels on one started to warp. I seem to have the glove wired correctly, but need to fix the length of time and hot battery problems.
The 1.2 volts determines how much heat is output(vs. a 9 Volt), and the 2500 maH determines how long heat is output, is this correct ?
Any help is much appreciated !
