App weigh runs battery out after a couple weeks or less

I did the same thing when I took delivery of my new trailer. I put them on both the tractor and trailer since they were so cheap. 6 months in and they still are very accurate when compared to a cat scale.

 

Try different batteries that aren’t cheap ones like the Amazon ones.They drain quicker than the ones that came with the Appweigh.

 

Even when I have them on the fast refresh mode or whatever they are called They don’t go through batteries that fast.I bought some cheap ones off of Amazon as well and they don’t last very long.Once I go through them in going to buy small packs of several name brand ones and see which last the longest.
