Any Protection Required for AccuRechargeable Battery Powered Device?

I created a device which is powered with 6 NiMH AA accumulatorsrechargeable batteries. The device uses between 10-100mA current. It is nothing special about it, there are some foil and electrolyte capacitors from + to - to stabilize the power of some chips and there is a microcontroller.

As I understand, the NiMH accumulatorsrechargeable batteries are sensitive for short-circuits. So I wonder if over time an element fails this could lead to a short-circuit.

It there any protection for the accumulatorsrechargeable batteries necessary for a such setup to protect the accumulatorsbatteries? Or more precise: Is it usual to add some protection for the accumulatorrechargeable batteries in accumulatorbattery powered devices?
