If you turn the E20 up-side-down, take out all marked srews. Turn it again carefully. You now can open it. You'll find the battery a little left of the centre. It looks like the back-up-battery of a computer motherboard, just a little bigger.

Succes in trying!

You still have to remove the 7 screws from the PCB (printed circuit board) were the battery is mounted on. So you can lift the print a little at the battery side and remove the battery. Otherways the back plate with the in & output holes are in the way to shove the battery backwards out of its holder.

Peace of cake... just be a little careful with the attached PCB cables.

Original battery type: Novel Lithium Battery CR2032 3V Made in Japan :o)
