Simon,
60 milliamps is 0.060 amps. This would be 1.44 amp hours per day, 10 amp
hours per week, 43 amp hours per month, etc. Since the draw is on-off
instead of steady the actual drain would be less.
How long the battery would last depends on the battery size, condition,
& how often the car is driven to recharge it. If your battery was
originally rated at 60 amp hours, the battery would be discharged maybe
1/3 in a month. If the battery is old or in poor condition, it might
very well have less than it's original capacity & go flat sooner.
I would expect most batteries to last at least a month without driving
before going flat.
A battery shop or similar can do a battery capacity/load test to
determine it's exact condition.
