An mAh rating only measures the total amount of charge in the battery.
The only think that affects how much power is delivered is the voltage;
if both batteries provide the same voltage, then a 1700 mAh battery will
not deliver more current to your winder than a 1300 mAh battery; it will
just last about 30% longer.
A smaller battery is only likely to be able to deliver a lower current
before exhibiting a voltage drop, but you shouldn't be able to harm the
winder, no matter how large the battery, as long as you don't exceed the
peak voltage it was designed to take. I doubt if any equipment designed
to take such widely-varying replaceable batteries as AA pencells would be
assuming any level of voltage drop; it should be fine at the peak voltage.
