Review on 🔋 Synergy Digital Flashlight Battery: Compatible with Streamlight STINGER LED Flashlight, Ni-CD, 3.6V, 1600mAh – Ultra High Capacity by Sidewinders Murphy

I had to return the battery. I'm not sure if I received a defective battery or if it isn't a direct replacement for a 75175 battery. The battery I received had a white outer shell covering the negative outer ring. Checking the voltage from the back of the battery to the positive inner ring contact showed the correct 3.6 volts, but checking from the inner positive ring to the outer negative ring showed no voltage. Without the negative outer ring, the flashlight will not work and cannot be charged in the Stinger 75203 charger. As mentioned, the battery I received had a white outer shell, so it didn't exactly match the picture (color doesn't matter), but the model number in the picture is the same as the one i received. Wondering if anyone has encountered the same problem.
