Testing current draw

Huw, Larry,

	That (Huw's assumption that the battery / charger may not be working
correctly) seems quite sensible, lets do some ball park figures:

Current draw = 0.017 A (0.204 Watts)

Assume the battery is 48Ah (I think this is about the capacity of a normal
battery - I'm sure it won't be any less)

If the battery is fully charged then it should last with a drain of 0.017A
for:

48 / 0.017 = 2823 hours = 117 days  = 16.8 weeks !
