This battery came up in a search for a Ryobi 14.4 battery. It simply doesn't fit Ryobi tools. Though it looks very similar, it is not the correct battery.

I used this battery pack to rebuild a 14.4V Harbor Freight battery pack, which is no longer available. The rebuilt cells work great, and gave me a savings of $35.00 over having the cells rebuilt commercially. I rearranged the cells from the Denali to fit into the Harbor Freight battery shell and completed the connections using nickel strips from the old HF cells.

One caveat though, I had to transfer the thermal switch from the old packs to the new batteries so that the Ryobi charger would function properly. You can't beat the price of these Denali battery packs. It connects from the negative side of one of the batteries to the third terminal contact. I successfully rebuilt two 14.4v Ryobi battery packs based on the previous reviews. My charger has yellow, green, & red lights to indicate charging status It's a minor detail, but an important part of the charging circuit. I call it a great deal. This is a fairly easy thing to remove from the old batteries and solder onto the new batteries.

I hope the Denali batteries will last a little longer than that. We'll see. So, what you have to do is take out all of the screws from your dead Ryobi battery case and remove the dead batteries. Now remove all of the screws from the Denali battery case and remove that battery set. After using my "new" battery pack, I've noticed that the Denali batteries charge faster and last longer than the Ryobi batteries did when in use. I bought this battery pack because it looked like it would fit in the Ryobi 14.4 tools.

BUT, the NiCad batteries from the Denali battery case will fit perfectly into a Ryobi case. You may have to pry them out a little bit and the batteries will come out as a complete set. The Ryobi battery pack only lasted about 8 months before it died. The Ryobi charger will recognize the Denali battery set and charge them correctly. It doesn't - by a fraction of an inch. Like the Ryobi batteries, you may have to pry the set out.

And the Denali battery pack is less than half the cost of a new Ryobi battery pack. Now, install the Denali batteries in the Ryobi case and replace the screws that hold the case together.

Sadly I don't own a Denali drill, but I was able to easily crack the case on this unit and take the Sub-C battery cells out and put them into my dead Ryobi 14.4v batteries. 5 minutes and I've got new batteries. Beats paying $50 for an "official" replacement battery.
