L R Nelson has been a solid and somewhat known manufacturer of turf
equipment for many years. Google on LRNelson, and when you get to their web
site, go to the 'landscape and turf". From there you can click on the model
you have and then download the instructions. They have the part number for
the replacement battery, but may also be available at a local Batteries Plus
store, or Radio Shack, etc..

This will also tell you how to program the valve, etc..

I am not familiar with that type of system, but I can tell you that the
valves are NOT run on batteries. They usually require 24 volts.
Yes,
the controller itself could be powered by a battery, but that is not
likely.


Your setup as you have described it is really weird.


Good luck !!

Well... it is a "Nelson" controller ( I've never heard of them
before ) and not a RainBird controller. It is battery
operated. Here is a link to a picture if anyone wants to see
what it looks like.

Suposedly, the battery should last for 10 years... but I don't
think that it's that old. I guess for an application where you
don't have readily available power, this is ok....
