I know this is a long shot, but I figure if there's a Religion category, i should be able to ask a question about AA batteries too
I have little to no electrical background but i will explain the situation
I have a powered door lock on the side door of my house. I'm sick of replacing the batteries almost weekly, so i'd like to see how i can replace them with an ac to dc adapter
I have seen the first 20 google search results, but i have an issue not covered by those links.
With the four AA batteries in the internal battery box in the lock, positioned in series
when i measure the battery box +/- it reads 5.98 volts dc, and the lock works perfectly.
when i move the battery box to the other end of a 20 foot copper wire run, the voltage is still the same and the lock still works perfectly
when i connect an ac to dc adapter to the 20 foot wire instead of the battery box, the lock exhibits these symptoms:
with a DC6V 2.0A ac to dc adapter: it barely budges, the bolt doesn't move, but the lock is powered
with a DC6V 0.200A ac to dc adapter: it moves a little bit more but not enough to unlock it (have to put in the unlock code 7-8 times to move the bolt the 5 inches)
the dc adapters test at 6.28 volts DC output
so the question is what specifically can i do to get non-battery power to this lock?
