Query: electronic switch fails easily

One of my three remote units burnt out after only using it a half dozen times on 400 Watts of flouresent lighting. Control range for remote is not consistent. Sometimes it works from across the room. At other times I need to be 2 feetaway. Battery in remote is not a common AA or AAA. You have to buy an odd ball 12V miniature battery type 23AE, when it is time to replace it.
