my older model 9.6v ryobi charging station internal parts are broken Can i use the newer charging

Hello samson25 and welcome to the community!

Before you attempt to use the old parts, I would recommend you contact Ryobi and find the Service Center nearest you by calling 1-800-525-2579 or by logging on to www.ryobitools.com. 

Mixing parts from the new into the old or vice versa, may not always be a good idea, sometimes manufactures update internal parts for several reasons, some reasons may include an engineering design to extend or improve how the battery charges, or a safety improvement.
