1.5V Battery adaptors with magnet extension by valand70

Last crawled date: 3 years ago

Does it ever happened that you desperately need a battery (or few) and the only ones you have are of a different measure ?
Well, as long as the one you need is bigger than the ones you have, here is a little customizer to build your adaptors.
To extend the contact areas you can use different things...aluminum paper, a piece of metal, a screw, a spring, a piece of metal wire, or little magnets.
I have these little 1.5mmx5mm magnets that I just put on the + pole and the extension is done, add the sleeve and you have the battery you need...
Radius_1 is the diameter of the battery you need, Radius_2 is the diameter of the battery you have, same for heights.
The top hole too can be the size you like.
The measure for Height you enter is the total one, from bottom to the top of the positive pole; in the customizer is calculated a 1mm top clearance for the + side.
The only thing you should consider is to add about 0.15mm for the inner battery and the pole hole diameters.
Measures are tipically as follow:
Type=diameter x height
AAAA = 8.3 x 42.5mm
AAA = 10.5 x 44.5mm
AA = 14.5 x 50.5mm
A = 17 x 50mm
B = 21.5 x 60mm
C = 26.2 x 50mm
D = 34.2 x 61.5mm
Magnets 5x1.5mm
