Hello,
I very recently purchased this:
https://www.amazon.com/gp/product/B01MZIAJI0/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1
The 200219 Battery Monitor with Hall effect sensor.
Following the directions, in OAH i set it to 225AH, the capacity of my batteries. I use the down arrow to go past the LOP setting, press and hold OK to reset the time, and cycle the mode to show the battery is 100% full. Up arrow and leave it in the OUT setting.
I let it sit for over 12 hours in my RV with a fair amount of load, at time 8A. The OUT arrow is red. the 225Ah in the lower left display is not decreasing and the battery percentage is still 100%.
I was expecting the number 225AH to decrease as the amps got used, along with the battery percentage to decrease accordingly.
Please help.
