My Ryobi 36v battery is showing charge yet it is not powering the product, lights indicating charge don’t. Highlight when inserted into 2 different tools

SOURCE: battery charge indicator seems faulty.

Solved own problem. Bad conection between pcb and battery contact pins. Reheat each battery pin on the pcb carefully until solder reflow occurs then remove heat. PDA now repaired

Ryobi batteries are specific to each Ryobi model, so please write down which model number or the original battery part number you have. How old are the batteries?
I had the same problem with many bateries I had at home, like cell-phone batteries and also some power tool bateries. Did not have any Ryobi power tools tho, so don't hold me acountable if this doesn't apply to your hardware:)
Many batteries have the "memory effect" which means that if the battery was not completely empty when it was set to recharge it might now only recharge to the level it was emptied to, so for instance if you used the power tool for 10 mins and the battery emptied to, lets say, 90% capacity, it might occure that the next time you recharge the battery it will only charge to it's 90% maximum...doing that many times lowers the maximum recharge capacity. As I heard the new Li-Ion batteries do not have this problem.
I hope this makes some sence as my english is not that good and it was a bit hard explaining my thoughts:)

sound to me like you have a bad battery, a lot of ryobi batterys don't last like they should i have had the same problem, but my battery was less than a year old and i took it back and they give me a new one.
