H8P5 Battery

I found discussion about the interactive processor internal battery but nothing about illumination. Can I replace the battery in the illumination processor? Has anybody done it? What's involved and is it the same battery as interactive? If not does anyone have a part# etc?

Tech support will give you the model number. It does require some soldering. I found it was cheaper to connect the processor to a UPS.

I have an H8P5 processor (H48-120) and would like to know what battery is uses so I can keep project database in memory alive during a power failure. I'll eventually add a UPS, but that will require re-wiring from the mains. Thanks.
