@independent - I have a veritable ton of batteries for all my Nxx0's ...
that really isn't the issue....
1-When batteries for the Nxx0 device lines cease to be made what then?...That is the last hurrah for our devices then. They are bound to the batts. just to power them on ..forget even running them 5 minutes let alone a day...we are completely at the mercy of "must-having-the-exact-battery-type" forever otherwise...and it is laughable that 5-10-20 yrs from now I'll be able to find a proper batt to use on ANY of my Nxx0's...However it isn't laughable that I won't be using my Nxx0's in 20 years from now ...I've been using a few of them for what ?...7-8 yrs-ish? .. so far quite happily....what's another 20 yrs to my lovely n800's or n810's?...

-For me...It's also about seeing if I can do this... afterward do a vid showing exactly how to do it easy-peasy ...post it...

-AAAANNNNDDD I get to piss around and make a stupidly high-heat resistant dummy-battery form to house the electo-bits outta deer antler ...that is reason enough right there....

@pichlo
ah! thanks pichlo!
I'm sure you have just given me the 1st two to three years of electrical engineering right there
Ok....I do have a couple projects I need to wrap up 1st...
So...In the new year... February in fact ....
I will be starting down the road to self-determined electocuticide ...
'tween now and then I'll get what materials I need and bone-up on what I need to do...following your advice pichlo...
Come Feb when I start...I'm sure I'll have more questions then...
