Question
My rain dials battery goes weak very soon so I just want to know how to fix this problem. My second problem is whenever the transformer gets heated it lessens its output. To be clearer its output is zero volts .What抯 the solution to these problems? Waiting for Your reply.

Answer
Dear Abdulrehman, I hope this helps. The battery will only hold them memory, when the power goes out. Once the power goes out, then the battery will be discharged. Your problem, is that if the transformer stops working, the battery is called upon to hold the memory, thus the battery is being drained. The battery will not run the system, it will only hold the memory if the power fails. Your problem, is that you need to replace your transformer, because it is faulty. Good luck and let me know if I can be of anymore help, thanks and have a great day.
