Ryobi P115 is an 18V battery charger. However, Ryobi Manual did not mention the current rating of P115. if the current rating of Ryobi P115 is 50% higher than your 18V Lithium Battery it will charge. but if it's less than or equal, it will not.

Check the battery with your multimeter. If it reads below 36 volts (or whatever the cutoff point is) it may be damaged. But before you run off and buy a new one, use the multimeter to check the voltage from the charger. Or borrow a good battery and see how your charger behaves. that way, you can identify the cause of the problem

test the battery with DMM-Digital Multi-Tester. when full charge a 36V battery measures 37-38 Volts. if battery is full charge the problem is your electric drill bring it to service center maybe need to replace carbon brush or the motor.

Not likely.

I believe it is a P105 18V lithium battery.

You have a weak cell in the battery therefore it isn't producing enough amps. Needs to be replaced.

The battery has failed. Whether the battery can be reconditioned is not the question. The battery charger is condemning the battery when it does this. There are some battery fixes on you tube where a second battery can be used to get the dead battery off the zero voltage or low voltage limit that the charger is seeing. My response that the battery has failed is based on the charger symptoms and not on whether the battery can be reconditioned.

I suspect the little ball bearings are out, possibly fell through the holes. Age and use and abrasive dust will cause this. You will need parts to replace the bit holder completely.

in the hand book it states that the charging period for new batteries can be up to 6 hours

all batteries wear out only need to change out battery unless charger is malfunctioning

The wires on the brushes sometimes shake loose , tool repair shop ,, or try it yourself ,, remember. Small parts ,, take pictures , tiny wires , may need to be soldered back in place ...

Verify electric contact brushes. They may be worn out on the motor.

Brand new from Home Depot - $70 - used I would say $25 - is fair If you need further help, reach me via phone at https://www.6ya.com/expert/michael_e7c2c48c6e65f808

How long have you left battery on charger? It will take about 3 1/2 hrs to fully charge. t is probably not a good idea to leave the battery in the charger for long periods of time though, so once it is fully charged put it back in the drill. When fully charged the green led will turn solid. This link will have more info on charger and battery. http://powertool.manualsonline.com/manuals/mfg/ryobi/130155001.html?p=2 C
