Polar T31 Watch Battery Replacement

I had another brand of star tracker that my toddler got her hands on so this was its replacement. The polar alignment camera with this setup is amazing. All my subs are spot on from one to another which I had difficulty attaining with the alignment scope my other tracker had for polar alignment. I'm using a DSLR and a 135mm lens. Pros: Small size for easy transport. Polar camera makes polar alignment very accurate and easy. Tracks like you would expect it to. Built in chargeable battery. Cons: No way to control camera shutter without an additional hand controller which is sold separately. You'll need an intervalometer if your camera can't do multiple long exposures by itself.

Used this charger on a polar bear safari. Super fast charging of both batteries. Charger checks tests the batteries for power and will apply more charge to that battery than the second while still charging both. good for maintaining battery life and charge speed.

One battery would not last a whole day on A7M4, so having one replacement is necessary.
