Is there a safe or better way of using an AAA battery in place of an AA battery in small electronic devices/ sensors, when in bind like pandemic?
For possible use in small electronic devices without moving parts; remotes (IR, Bluetooth, RF etc) or sensors (temperature/ humidity type sensors) etc.
PS: Not using a motor, so this question title though similar, is not related.
There are plenty of sites/ you tube videos that talk about using an aluminum foil as a connector.
Given how it's a crumpled sheet and not a SOLID type connector, I would think it is subject to weird electrical properties (and hence not recommended), as compared to a SOLID connector.
Only if devices has some kind of "spring loaded" connector which allowed them to use "either" AA or AAA.
(Although FireStick 4K remote connectors are nice cylinders (spring loaded) & not just thin coiled dpring wires (unless something of that type might help).
Is there a safe, decent, SHAPE/ OBJECT / MATERIAL that can be easily be used in place without the flaws with such hacks with foil?
So, the solution would revolved around:
- Conductive item (preferably solid) to fill in for the Length & not dodge / wiggle around
- Non conductive surround/ wrap around stuff to fill in for the Width an prevent dodge / wiggle around
Given the uncertain times ahead of us (this could have impact for 6-12 months on all kinds of supply), I've found both answers useful - and better than Foil ball. Open to more.
PS: We are in an asian city locality surrounded by Hot Zones - even medicine & food are hard to procure. A friends building, one case was detected - police lock down for 2 weeks now.
Its not the time to be close minded or nit-picky given that both are decent solutions, if one ends up with AAA's at home (due large no of devices) and needs AA in a pinch.
- One "adapter-kit" is something to keep, get if one is able to, for longer term, a must have that I was unaware of, given that AAA batteries & devices are common & around
- (kinda like have all kids of screwdriver heads even if you rarely use a certain type),
- Other - DIY w object or similar from home/ hardware (a bolt in linked SE answer)
- Would appreciate more such "DIY" ideas with the decent "electrical properties", better than a foil ball.
