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

I have used alot of battery type drills and other action tools . Ryobi is on the lower end of the market as opposed to Milwaulkee and Dewalt . But my experience with battery operated tool charging equipment is that if the light is green and it's blinking , I would say it's charging . When the light goes off or stays on . I would say it's charged . Leaving the battery or batteries in the charging unit for 24 hours will not hurt the battery . My solution here is put it in the charger , and check it 12 hours later !

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.

I work with cordless tools for a liveing. Its the batterys that are the expensive part ryobi will sell the tools dirt cheap. Iwould contect RYOBI the batterys may have some kind of warranty they don't realy say and they can not be servised. Hears a # 1800 525 2579 this is probably why they gave you so many batterys first place i've never heard of 7 batterys in one combo pack

No. The P110 is for NiCad batteries. Any of the Li-Ion chargers like the P113 are backwards compatible and can charge either but do not try to charge Li_ion batteries in a NiCad or NiHi charger.

Ryobi is one of the cheapest drills. They are good for small projects. You need to upgrade to a better drill like milwalkie or Dewalt. Seems if you are drilling in concrete you need a corded hammerdrill. This will get the job done.

Do not try this since the charging circuit for lithium batteries are different than nicad! Improper charging of lithum batteries can cause a fire.

I would not say they are not defected, but I think they are not getting fully charged. I have the same problem with my battery once I have used it all day and the red light comes on from the fuel gauge. I have the P104 battery. I would return your charger and try to charge them on the new one first. If you have the same trouble, then return the batteries for new ones.

Yes, they will get hot... that is normal...if they get too hot the charger will shut down and give and error flash...

How long have these 2 batteries been standing idle without being charged? Lithium ion batteries can still discharge if left for too long. There is a voltage detector which detects whether the cells are too far discharged to be safely charged again and if that occurs the circuit is broken and the batteries will be deffective in the charger.
I have had the same problem with these and other LI batteries. Answer is replace the batteries and then make sure they are given a quick charge on a regular basis. However common advice seems to be that LI's should not be kept fully charged, but just partially charged until needed, then charge them for use, especially if usage is sporadic

This applies to Li-ion. NiCd is probably somewhat different.

Unscrew four security screws on the bottom of the battery. If you don't have the right bit you can grind down the center pins in the screw heads and use a T15 bit.

Unscrew the hex-head screw in the center of the protruding post at the top of the battery. It may be non-standard in size but a small metric hex key wrench works if you are gentle. The four corners of the battery cover should be loose now.

There are still two plastic clips holding the top cover to the main unit near the centers of the long dimensions. Gently push a knife blade into the crack between bottom and top to release the clip on each side.

As you lift the top cover off you should push down on the contacts near the top of the post so you don't pull on the attaching wires. Eventually the contacts should pop free and the top cover detaches.

Detach the wiring harness for the status LED from the circuit board. You can now remove the combined circuit board and battery pack from the lower case.

Six screws attach the circuit board to the battery assembly, along with several solder connections, but you probably don't need to go this far. You can now test and possibly replace individual cells.

something is wrong. take it back if possible.

Ryobi Two 18V... | Answered on Oct 02, 2010

One thing I have found with the ryobi 18V batteries in particular, and cordless tool batteries in general, is that if the battery is completely dead, the charger simply will not recognize it. This is referred to as a "threshold level" by some manufacturers. One solution that has worked well for me in the past is to take a battery that is known to be good and has a charge and use small jumpers to hook it to the problem battery, terminal for terminal, for about 1 to 1 1/2 minutes, much like jumpstarting a car. Then place the problem battery back in the charger and more often then not, it will take a full charge. Wear safety glasses any time you're messing around with batteries, because although the risk of explosion is minimal, it is still a risk.

If both batteries won't hold a charge the problem may be the charger (not providing a full charge). If one battery is OK and one not holding a charge, the problem is probably a defect with the battery. I know there expensive, (I recently had to replace one for DeWalt).

I am just amazed at some of the intellectual answers some of these folk recieve to the questions of the issues they are having. theresagould needs to resolder connection,.. This is true. But that was nt what he asked to recieve help for. He asked how and/or where he can get a wiring diagram. And what he gets back is hold contacts on battery terminals. Unbelievable!!!
