Rated 4.5 out of 5 by 50 reviewers.
Rated 5.0 out of 5.0 by Ryobi P126 Kit - Good Deal This kit is an excellent value with the included P114 IntelliPort charger and the P103 Compact LiIon battery. The P114 is the next generation of Dual Chemistry chargers, taking the P113 one step further by adding the IntelliPort technology. With Intelliport technology, there's no need to worry about overcharging your battery. In fact, this charger is designed to let you keep a battery plugged in at all times so it will be ready when you are. The charger is Energy Star compliant and draws 10x less power when idle than its predecessor, the P113 (as per my Kill-A-Watt). The P103 Compact LiIon battery is much lighter weight that a full-sized battery and this makes it a great choice for use with a drill or other hand tool that you're likely to be carrying all day. The P103 was originally released with 1.3Ah cells (rated 24Wh), and then in early 2012 Ryobi started selling the P103 with 1.5Ah cells (rated 28Wh). The high quality Samsung cells inside the P103 ensure that the battery delivers every bit of its rated power. As with any Ryobi kit containing LiIon batteries, check the packaging or battery for the manufacture date before making your purchase (e.g., CS1345 = 2013, week 45). Always select the newest package, and avoid purchasing units manufactured more than a year old as Ryobi ships batteries with a very low charge level and LiIon cells don't fare well when sitting discharged for such a long time. Note that fully charged LiIon cells can sit idle for more than a year with no problem, but this isn't done by manufacturers for both cost and safety reasons. January 28, 2015
Rated 5.0 out of 5.0 by Worth Every Penny New Lith-ion battery works excellent, lighter and much more powerful, and the charger revived my old battery as well, amazing value. June 26, 2011
Rated 5.0 out of 5.0 by Very good product but battery life is not consistant I have almost every 18-Volt ONE+ tool Ryobi makes. I am very happy with them, however, the lithium battery life is inconsistant. Some of them fail very early, while others have lasted me for years. I have had four early failures, and unfortunately I had not kept my receipts except for one. None of the tools have failed Keep your battery receipts, and the store will give you a replacement within the three years of the warranty. Alternatively, the same company (thus it is not a competitor) makes a premium line of tools under the name of Ridgid, also sold exclusively at Home Depot. The Ridgid line has a lifetime warranty, including the batteries. May 25, 2012
Rated 2.0 out of 5.0 by Great battery but Ryobi has horrible service Most of the time you will get a good battery from Ryobi, but sometimes they don't last and Ryobi doesn't honor the warranty unless you can return it to Home Depot. I like the Ryobi products, but if you get something that goes bad after a few months, you may as well just throw it away. February 27, 2015
Rated 5.0 out of 5.0 by So far very impressed. I only have one day's experience with this product but so far I am very impressed. I had several Nicad batteries that would not hold a charge and two Li-Ion batteries that my old charger said were defective. I bought this kit to get me a new battery and I thought the new Intelliport charger might be good to have. It charged both "defective" batteries without a hitch. I am now charging my old nicads to see if it will help them out too but even if it just keeps my lithium batteries going I am very happy. Especially at $60 for the charger and a new battery.

Rated 4.0 out of 5.0 by wonderful i have bought 2 of these upgrade kits mainly so I could have two of the chargers. The batteries work wonderful all of my tools seem better and more powerful than new with the Ni-Cad batteries. Just need to add more Lithium batteries. October 13, 2011
Rated 5.0 out of 5.0 by Great purchase I have a couple of Nicad 18v batteries that would no longer take a charge. One hadn't worked in a year. The charger revived both of the Nicad batteries. The charger is worth the price itself, with a bonus being a new lithium battery. April 14, 2012
Rated 4.0 out of 5.0 by thinner, lighter, more talented I've used the charger on both NiCAD and LiON batteries -- and it works well and quickly. It effectively uses its two red / green LEDs to provide info on its state and the charging process. It also seems to have helped bring some charge back to some NiCAD batteries that I'd considered dead. I use sharpies and post-it tape on each of my batteries to keep track of individual battery details (e.g., purchase date and charged voltage). I'm using the LiON battery that came bundled with the charger primarily on the older, blue Ryobi drill motors, and while the battery is much lighter than the NiCAD batteries, it still weighs enough to keep the drill motor balanced when I put a drill motor down on the battery. I don't have experience with how long the battery service life will be, but right now it has significantly more power than the NiCADs -- and a lot less weight. A great upgrade for my "old" Ryobi cordless tools. So far, it has been good for a month. I hope it lasts for years... June 26, 2012
