Standy by battery on Horstmann H37 XL Progammer?

I have a Horstmann ChannelPlus H37 Series 2 Three Channel Programmer.
Instructions state it has a non-rechargeable, non serviceable long life battery which will maintain the clock & programme settings with mains supply disconnected.
The display on my programmer is not lighting up. I have tried the reset procedure detailed in the manual to no effect.
Does the stand by battery have a life span? as during the Covid pandemic the mains supply to the programmer was turned off as it is in a holiday home abroad that I could not visit.
If the battery is now dead can I just buy the same replacement programmer and fit it to the existing backplate?

You should easily be able to fit a replacement on the existing back plate.

I had a similar issue with an ESI programmer. On the basis of having nothing to lose I took it apart and fitted a new lithium coin cell but I future proofed it by getting a suitable coin cell holder and using an ordinary coin cell without solder tags.

Simple enough but there again, I spent many years as an electronic test engineer.
