Sorta non rc ??... I had to replace my battery in my fios box ...u know that annoying beeping. I have a hobbico torque master battery sittin around since 2008 it met the 12v 7mah spec... I plugged it in and it worked..I ordered another battery anyway but is it safe since I've had it since 2008? It is a sealed battery..I have used the battery a couple times but not in a year or so.
I would contact Hobbico and ask them.
