OK. With two Eneloop pro 2,500mA/H batteries in series per glove, you would get approx 1v*2= 2V average per glove and, say, with an average current of 2A (2,000mA), that would give you a duration of around 30 minutes and 2V*2A= 4W of average heating per glove.
To get this, the resistance of the heating wire in each glove should be 2V/2A= 1 Ohm.
Attached is the data sheet for an Eneloop pro 2,500mA/h NMH AA battery:
