Is there 2 type of battery chargers for ryobi one+ and lithium 18v one +

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 output on transformer, 2 check pcb ,could be a regulator

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.

(who has the Ryobi 12V drill and charger, a few of the 4V tools, and a number of the ONE+ 18V devices and chargers. The single chemistry battery charger is not used much any more.)

That is true the One+ 18V Li-Ion battery packs will work in any One+ 18V Ryobi tool. However the Lithium ion batteries will not charge in the original P110 NiCd charger. You will need one of the the new series Ryobi One+ 18V "dual chemistry" chargers for that. The will charge both types of battery packs.

You are the thrid person in the last couple of days with this same problem and i check who was posting the problems all differant people all RYOBI 18V lithium-ion batterys and they all got them for christmas. SOMETHING is not right there is now warranty on the batterys but there is one on faulty workmenship there must be a problem with this type of battery good luck

If you have a P100 NiCad battery, the charger for that will not charge the new Lithium Ion P103 or P104 batteries. You need a specialised Ryobi Lithium Ion battery charger like this one

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.

No, just return it, for the money they should give you one that works. It is common to get a defective Ryobi 18v lithium battery. I've had 2 out of 7 purchased that wouldn't hold a charge. But when you get a good one they work awesome!

Just got a reply from Ryobi tech service and it says that "all Ryobi 18V platform power tools can accept and use the lithium batterys, but you must use the charger for the lithium to recharge them. Hope this helps. Dave
