Minimum DCS remote battery voltage required to operate

Are you sure the batteries aren’t getting knocked off the terminals? That block of foam on the back of the door wears out and the batteries get dislodged. That will randomly shut off the remote.

I stick a thin piece of foam in there to hold them tight.  However, at 1.3V, marginal, remember the voltage will drop when the display is operating, you're measuring them with no load.

When the remote shuts off and won't turn on I put in new batteries .

I would not wait until the batteries become low because your asking for problems, a small voltage transients might cause a corrupted erratic change and cause the remote not to understand what the tiu is asking or sending while sending packets back and fourth. just my input IMO ! batteries are cheap!

Truthfully, there's no issue using batteries until the remote notices they're low.  I've never experienced, or even heard of, real damage to the equipment from low batteries.  It's a normal happening, and it's pretty well covered by the design of the various remotes.  Lots of things are cheap, but I don't buy them until I need them.  I have customers that want new traction tires regularly, even though the old ones are perfectly fine.  Just another way to throw money away.

I run my DCS remotes on rechargeable NiMh batteries, and they only provide maybe 1.3V when fully charged, the remotes run for weeks on them.

I'd rather pool all those savings and buy a new locomotive in a few months.

Boilermaker nailed it. I “assumed” the foam on the inside of the cover would keep things tight- wrong! Truthfully, the door latch broke off years ago and a rubber band holds it just as snug. I took GRJ’s advice about adding thin foam and all systems are go!
