Any tips appreciated- should I mod it to a larger CMOS battery like a lithium type? Anybody who has done a 905 pls chime in?
That's a better choice of battery. It has leads. Much better than holder and a CR2450. The strip of metal underneath the
battery (- lead) is kind of tricky to cut. Good Luck to ya, also.
They are spot welded little flat leads. They look like a button holder, but they are heat welded to the button. Very hard to
get loose, some use a dremel, but metal filings and live circuits kinda make me nervous..
Quick question. How long can the battery be disconnected before the memory risks being wiped out when replacing it? If it's only safe for a few seconds then it's probably best to solder in a battery holder first in order to quickly put in a new battery 1 second after cutting off the old battery's positive leg.
Also, is it better to leave the unit plugged in to the wall or can it be unplugged?
Ok, so it's safe to connect the new battery in parallel? As you know, doing this will double the amperage on the board but the voltage will remain the same. Can we take our time to ensure the connection is good or should we cut off the old battery immediately after connecting the new one?
