AA Dummy Cell Battery Eliminator
A printed AA-sized dummy cell (14.2 mm diameter, 47 mm body, about 50.5 mm overall with an M3 socket-head cap screw as the + nub) that lets you power a wall clock, remote, toy or sensor from a 1.5–3 V supply instead of batteries. The two M3 terminal screws self-tap into 2.6 mm pilot holes, and the supply wires run in two 1.8 mm side grooves and tuck under the screw heads through end-face channels. The – end has a 7 mm × 1.6 mm counterbore so a low-head M3 screw sits almost flush.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
AA Screw Terminal Battery Holder
A four-cell AA holder (98 x 74 x 20 mm) with snap-in open-top channels on 18 mm pitch for 14.5 x 50.5 mm cells, so you can see and swap cells without a tool. Each cell end gets a contact window plus an M3 heat-set boss (4.0 mm bore) on top of the 9 mm end wall, so brass straps and ring-lug wires bolt down with M3 screws instead of being soldered to flimsy tabs; four corner ears take M3 clearance screws for chassis mounting.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
