Question about Ryobi Drills
They are for the charger to know the voltage in the battery to turn on or off charging. some just need 3 connections and the 4th is just a dead connection. or can be for location only so you don't put the wrong battery in. as they do other voltage batteries that look the same fitting.

2 are for output and the others are from the charger to the battery .

talked to Ryobi and they are vague. It can either mean that the battery is bad, or the charger is bad and another one that maybe the contacts of the battery are dirty or not seating fully in charger. What I would look for in this instance first unplug the charger and look into charging slot to make sure the terminals of the charger are not bent and they come out into the cavity where battery would go. If not gently pull terminal into opening and retry. Sorry I couldn't be of more assistance

You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.
