IF your battery is having 3 contacts you are lucky but your charger must have also that 3 contacts because that thirth contact is a deep discharge-protection to warn you if the cells are become to low for DC voltage the switch in the machine -the battery and the loader must all off them 3 contacts to will that worked.
The motor stopped immediately if the voltage is becomming to low .the thirth contact is responsible for the protection.
Batteries are expensive wrong batteries more but there are ways for rebuild the switch and batterie contactplate as first. and after that the charger. it will give a longer freshment of capacity.

SOURCE: Very little juice in freshly charged batteries

have you tried the batterys in any other tool?

you would also need to check the voltage of the batterys they should be at least 18 volts (19 prefered)

then if the batterys do not show charged you would need to make sure the battery charger is putting out voltage.

After that contact your closest Ryobi service center we would check that for free to let you know what you need, I am sure you local place would do the same.

SOURCE: 4 contact points on charger yet only 3 0n rhe Battery. what do they do actually. I understand the + and -

They are to do with the feed back for the PCB in the charger and tell it when to switch it off and also sense the condition/temp of the battery.

Goes through charging process Red light blinks then green light blinks like it is charging then after a few seconds solid green as if fully charged but it is still dead


I had the same problem. Your battery sounds like it got drained too much. The voltage on the battery is too low for the charger to charge. I looked on YouTube (how to charge battery that won't charge). I actually tried this today. I had a battery attached to one of those flashlights from a combo pack and the battery was drained down to 0.64v. The video I watched said take a higher voltage batter and boost it. Like a 20v to boost your 18v. Attach wires from one to the other. + to + and - to - I didn't have any. So what I did was stick 9v batteries together + to - in series I had 5 laying around. I taped a wire to the exposed terminals on the two end batteries and tapped the wire on the battery, which only brought it up to about 2.3volts. Then I just held the two wire on the battery for about a minute. It went up to about 6.3 volts I plugged it in the charger and it finally started charging. I don't know how well it will keep a charge. The batter is 10 or 12 years old. Hope this helps. And check YouTube. There is a lot of videos there.

Will the P110 charger charge a lithium ion battery


No, the P110, 18V NiCad battery charger, will not charge a 18V lithium ion battery. You need one of the dual-chemistry chargers. If you have the Ryobi ONE+ batteries, you can get the P117 charger ($30) or a charger with an extra battery (P126) from a store like Home Depot. A 6 battery charger and a 12V in-car charger are also available.

I wish that I had better news for you.

I do not recommend connecting anything but the factor charger to the battery. No 12v will not not charge an 18v battery.
They can BLOW UP if you apply too much current.
The correct charger can be found cheap. Look on craigs list under tools.
Good Luck

The testing light continues to blink when I plug in a battery. The batteries appear to still work but they don't charge or the charger won't charge them. I'm not sure what's wrong.


Check the date on the battery, all batteries are dated, if they are not 2 years old, they will be replaced for free, that goes for the charger too. I have the same charger, but I didn't get the li-ion batteries yet, still using the ni-mh or whatever they are, they were replaced, no problem by home depot. If they don't have a date, they have a date code, you can look that up on line. Check it out.

Can you charge ryobi lithium batteries in a regular ryobi charger?


NO! Never charge lithium batteries in a charger designed for nickle based batteries like the NiHi your old charger was meant for. Ryobi did design the new Lithium charger to be backwards compatible so you can charge your older 18V NiHi batteries in the Lithium 18V charger.
Also note, NEVER miss-match the voltage, for example, make sure you are not trying to charge 12V batteries in an 18V charger unless the manufacturer has specifically stated that the charger is capable of multiple voltages.
