Yes having problem with % of battery charge, when first received battery was at 12.9v once hooked up to charge controller said 12.9v but only 83% charged.. The battery has been charging daily for 3+ weeks with no load, as soon as the charge controller starts charging in no time, about 15 to 20min, it says 100% charged then the controller goes to boost, then after the hour goes to float.. As soon as the sun goes down the battery % drops back to 83% by the next morning..
What is this and why does it happen, is the battery not getting charged fully or is there a way to calibrate the charge controller battery charge % to read full 100% charge instead of 83% ? Thanks
