Which model of the batteries are you using? I got some of the 1/2 height ones and they were dead in less than 6 months. ...and of course I forgot to register them so I was REAL glad when the high capacity batteries went on for cheap.

Less then 6 month for the Lithium packs? wow that's bad I still have my 18v Bosch slim pack batteries working fine for the last 2 years. I would have thought the new Ryobi packs would have done better.:dunno:

Probably not the newest model.

The one compact LithIon+ pack I had lasted no longer than a few months either. It was very common for the smaller capacity ones to die prematurely.

This is a great page of info on the various Ryobi packs: http://toolboyworld.com/eBay/Ryobi_Batteries.htm

The "half height" ones are the P102, P103 and P107. The P107 is the newest and uses excellent cells, so they should last as long as any decent pack.

The small capacity pack that I have that died prematurely is the P103. But reading around, its possible the newer tech. Chargers might be able to "revive" the pack.....my old model charger doesnt sense the battery. It just flashes red light which indicates an error. The newer chargers might not do that...I havent bought one yet to test the theory.

IIRC I got them around Christmas and left them in the garage during a cold snap. The new ones that I just bought I registered and from what I understand that makes them replaceable for the next two years. Old dogs do learn new tricks. Which reminds me I need to register the impact driver that I bought the other day.

Are you sure that isn't an Internet SKU? I am pretty sure store SKUs should be just six digits.
Definitely in store. Pulled it right off the bottom of a package of batteries

And I've used it when calling around to find them and their price

Okay, I was trying to use a Home Depot inventory checker online and it only accepts an 8 digit SKU. I wonder if what you are using is the UPC code? I think the chances of finding the batteries at this point are pretty much nil.

If any of you guys who had one of the compact lithiums that fried still have the dead pack, I'd be interested in taking it off your hands. I'm looking for a good housing.

Hey Chris, I'm the one who told ToolBoy about how to "revive" a pack that can get messed up by the old chargers. You can go in there and recharge each cell to 3.5 V +/- 0.15 v only, put it back together, put in the normal charger, and it will work to revive a pack if the cells are still good. If not, you can just replace one or more cells to make it good. The way the technology works, the chargers must read good voltage out of each cell or they will not charge the pack. It isn't really totally dead and sometimes not dead at all but may have a couple cells out of whack just slightly. Toolboy added the page to his site after I told him how to fix these!

If any others of you guys have any of the even cheaper two packs like the $30 or $40 range ones you wanted to sell, I could use another two pack or two for my dad. I know some of you guys loaded up on these! Share the joy! thx - Paul

Would home depot allow you to take from their recycled batteries bin?

Although I have only noticed the bin at one store it was choked full of Ryobi and Ridgid batteries.

i've done it before! They don't normally care at all. Best way to get shells for a project. I still need an old dead Milwaukee 18 v battery if anyone has one! Those are harder to find. From like the early 2000s. Also, most "dead" lithium packs really only have one or two bad cells in them. Two doner "bad" packs can often be combined with the good cells from one to replace the bad cells in the other and make a new pack good for 3-4 years for an hour of effort. These things are getting cheaper and cheaper now, so most would not do such things anymore, but when they were $100 each, that was worth the hour of effort. Can also do this to your Ridgid or Milwaukee packs using the more common Ryobi packs that get put in the recycle boxes more frequently. The cells are the same inside. This might make more sense to putz with as the Rigid or esp Milwaukee batteries are much more costly than the Ryobi. Replace the one or two bad cells, charge just those cells properly to same voltage as others in the pack or 3.5 v for all, and put back on your charger! They will work 90% of the time for free! Read up on lithium cells and packs before you do it though as very dangerous. Do it outside, fires are possible if you botch up the soldering. Must be done in 3 seconds or less. - Paul

Ok, now you done peaked my interest.

What are you using to charge individual cells?
What is the best way to identify the bad cell? Break them all free and test one by one?
How are you testing? Just attempt to charge and see if it takes?

Thanks

Correct me if I'm wrong but I tend to shy away from or even recommending amateurs with limited knowledge from soldering lithium batteries. Fires or worse could be a big short term issue versus buying the correct battery, especially at today's prices ($25.02 for 2-pack 4.0 Ryobi). I like the GJ battery adapter thread (rslaback) that is much safer for the user and the power tool.

I finally figured it out. Home Depot now has store SKUs that are much longer than six digits. The third party online SKU checkers truncate all SKUs at six digits so I can't use them to find stock. Oh well. HD probably ran out of six digit SKU numbers.

Hi, you can test each with a normal multimeter. You can charge individuals a few ways, I used another charged 18v battery! A few touches with probes will create a little spark but charge them right up. You can also use an actual power supply to do it if you wanted.

Agreed, 99% of normal people should never do any of this. But GJ has a few 1% ers, so for those capable it can be done. If you don't know for sure you are one of those 1%ers, don't try it. If you do mess with such, do it outside, wear a full face shield, and have a bucket of water handy if you did start a fire. Lithiums don't really explode, they catch on fire suddenly if they get too hot. - Paul

Recharging 'dead' lithium cells is risky.
Unlike NiCad cells, when lithium cells go below a critical voltage, about 2V, they rapidly degrade. They dissolve the copper out of the internal structures. When they are recharged above 2V they copper precipitates out, plating and growing copper grains in places they shouldn't be. This can result in a short in the internal structures, causing a fire.

Since some of you (as I quietly raise my own hand) are going to try anyway, always do the initial recharge in a fireproof area where any venting won't ventilate into living spaces. It's probably best to take the same precautions for the second recharge as well.

Remember, the only reason reviving battery packs has a chance of working is that the recharge safety limit is set conservatively e.g. 2.1V when damage occurs at 1.9V (temperature dependent). You might get lucky and catch the cell at 2.05V, when no damage has been done but the internal circuit is blocking the recharge.

Some good points. I should be very clear in my writings as well: I'm not talking about trying to recharge any dead cells (below that 2.1 v). I'm talking about taking some cells that are at higher voltage like 2.5 or 3 or 3.5 out of a "dead" pack and moving them over to replace other dead cells in another pack, then just recharging each to match same voltage. This is a very different thing, but cautions still apply. Not recommended for anyone who doesn't already know what they are doing. - Paul

I check the bin every time I am in a Home Depot. The problem is, since we moved 230 miles this summer that is about 6 times a year. The nearest to me now is 50 miles or so in a city we don't usually shop in.

I'll hook up some guys once my pos software is up and running. I bought them tax exempt, so I want to be careful about keeping track of them for now.

Home Depot has the Ryobi batteries on special for $99 again. Anyone think they will clearance them again, or did they learn their lesson about ordering too many?

How long will Home Depot refund the difference if the price drops? I plan to buy a set of these for myself at the $99 price, but I wouldn't mind if the price drops in the future so I save some money.

I think my HD had these for $84.??.

No price drop until at least post Fathers Day I would guess.

After that they might drop the price.
Christmas season up next.

Yea, I don't know if we will see the 25 dollar 2 packs this time around. It was awesome but I bet some people in ordering department got a stern talking to. They really over ordered for black friday.

I haven't actually been to Home Depot yet, but the ad I saw yesterday said $99. I have my doubts if they'll credit me if the price falls after Father's day, but we'll see I guess.

I'll shut up now as this won't be a hot deal until they start lowering the price again, if they ever do. It is still a lot better than paying $99 for one of these.

If you are a member of Ryobi Nation there might be a deal to get $20 off any 2 Ryobi selected items.
Check and see if the 2 pack is one of the items.

My HD had them back at $99 today.

Wouldn't be surprised if they lower it back down before Fathers Day.

No Ryobi Bluetooth radio in stock yet.

I picked up a set a month ago for $84 when it was posted they were back in stock. They didn't order a lot this time round as my local stores only had 20 or so in stock at each location.
