As long as the voltage is the same, you are OK. The extra 100mAh will give you extra capacity until the batteries run low and need recharging. The circuit will only draw it's design current irregardless of the battery capacity. You can put enough batteries in the circuit to have 1 amp or more of capacity, and as long as the voltage is 3v to the circuit, the circuit could care less. The board is not in danger of being fried.
More mAh equals more time before recharge.
