replacing 71b batteries without losing data

I have the HP-IL module (and no, I never did OFFIO), the Math module, a CMT 64K RAM module (front port), and a 4K HP memory module.  I have a 96KB CMT card-reader-port RAM module, but there seemed to have been some sort of configuration problem with it, and I had taken it out and never put it back because I haven't done anything in recent years that needed so much memory.  I don't remember why my Forth/Assembler module isn't in it.  I still use my 41cx with Clonix-D, HP-IL, XIO, and double XMem nearly every day, but I almost never use either of my 71's.  (I have a backup 71 that I got, surplus but never used, for a song, back before there was eBay.)
