Ryobi is a part of Techtronic Industries (TTI), a brand that includes Milwaukee, Dirt Devil, and Hoover products in its portfolio. Ryobi Power Tools specializes in making pro-featured power tools truly affordable for people looking to do a project around the home or make building their career. has a huge selection of equally affordable batteries. Batteries are essential to your cordless power tool. It's a good idea to have even two or three spare batteries in case the one being used suddenly runs out of juice mid-project. Even worse, the original battery will eventually come to its final end. That's when you turn to us.

Knowing the Right Battery to Choose
Please check your manual before purchasing a replacement battery for your power tool. Different chemistries, voltages, and capacity can be overwhelming. Multiple batteries may say they are compatible with the same model, while having entirely different specifications. Voltage is model specific. Sometimes, if your manual or manufacturer permits, however, you can get away with changing the chemistry or capacity of the battery you select. For example Ryobi CTH1802K specifies the battery should be 18V, that is set in stone. Still, one option for this tool is RY1820 which has a capacity of 2.0Ah and a chemistry of NiCD whereas RY1830 is 3.0Ah and NiMH chemistry. These batteries both fit the same models and are interchangeable. Here's how:

Ni-CD batteries last the shortest amount of time and need to be recharged often (but you get more charge cycles). Ni-MH batteries may cost more, however have no memory effect, they last longer due to a higher capacity, hold a longer charge, and they contain no toxic chemicals that are harmful. However, you won't get as many cycles for some Ni-MH batteries. Li-Ion has a very high energy/mass, meaning it is a light weight battery that will store a lot of energy with no memory effect. In general, the higher the capacity (mAh), the longer the battery will last. Installing batteries with a different capacity will not affect the operation of a device as long as the voltage matches. We hope this helps you find everything you are looking for in a flash
