Red wire connect positive power "+", Black wire connect "-" power negative pole. Specifications Battery type: lithium-ion battery. Battery capacity: 7800 mAh. Nominal voltage: 3.7 V. Fully charged: 4.2 V. Power: 28.86 Wh. Cut-off voltage: 2.95 V. Review: Straight swap, works perfectly. - Fits perfectly, my mirror started to show red at the led with no light when looking at the mirror. I took a chance and it is working like a new mirror again. It was a bit tricky to get the silly little plastic button back in place but with a little patience, I managed it. Just put some tape over the button before you remove the grub screws and it should come away with the base that holds the battery. Take a close look at the position of the plastic and if it drops off you will know which way it goes back in, as it's curved on one side. Hopefully it will last another 7 years, then I will be back for another battery. Review: Good product fits ST3002 - Although this battery has a higher mAH rating than my existing one, it had the same connection. Previous reviews said that it works in ST3002. I can confirm that it does fit and works well. Fitting was relatively easy, just use a bit of tape to hold the power button in place. Very pleased, just hope it lasts as long as the original. ## Features - This lithium ion pack is made of 3 balanced 2600mAh cells for a total of 7800mAh capacity!
