To replace the batteries and capacitors on a lithium battery E30 SI board you will need:

Two CR14250SE-FT batteries
Three 100uF/16v axial capacitors
One 10uF/16v radial capacitor
One 47uF/16v radial capacitor

When mounting the batteries, depending on production date, the double feet may be wider than original; this can be overcome by folding in one of the feet and soldering the remaining leg:

*** if the CR14250SE-FT batteries ever get discontinued, the cell size is 1/2aa rated at 3v with a 0.85ah capacity, replacements like Varta CR1/2aa 6127201301 or Panasonic BR-1/2AAE2PN should be suitable replacements.
