All The Single Ladies, Put A Switch On It

Girl buys new pack of fresh batteries. Girl doesn’t realize unused batteries lose their charge overtime albeit slowly but still, it’s like money slowly pissing away. If only there were a way to keep the internal charge from being active until you needed it. Girl figures it out. Put a switch on it. The science is simple. I mean you’re essentially just switching the anode off to prevent current from flowing but does this actually work? Energy doesn’t seem to be something that likes to stay put. Maybe one of you could speak to it, figuratively that is.

  • Great ideal! I think it's useful!

    What a spectacular display of the designer’s ignorance. Self-discharge results from unwanted chemical reactions and decomposition of unstable components within the cell. There is nothing at all to switch on and off.

      I suppose the comment about unused batteries could have been Yanko’s misunderstanding. A switch might be used to stop a device from using (typically a tiny trickle) of standby power, if it does not already have a physical switch built in on the outside of the device. For many devices and battery chemistries the standby current is probably small compared to the self-discharge rate anyway.

      But what devices are we talking about here? If you can be bothered cracking open the case, flicking a switch the batteries, replacing the case, then repeating the process again when you decide you want want to use the device, presumably you are putting the device into storage for a very long time. Why not just the batteries out altogether while you have the device open?

        And then re-use the batteries in another device.

        You've made good points, but that remark about ignorance really wasn't needed. Constructive critisism is only good if there is more constructiveness than critisism.

  • AlienzExist says:

    Its a 5 minute concept. Notice the one illustration used over and over. And typos on the actual battery.

  • Armin says:

    Btw, why not just use rechargeable batteries?! When you’re not using the device, charge them (if they’re Li-Ion etc.).

  • wodingdong says:

    good!awesome!

  • ChenJie says:

    think about the comic “pull the switch~~~” :-)
    maybe it can be better if there are lithium battery

  • XX says:

    that is interesting

  • ryan says:

    What a waste of time! why dun just take out the battery!

  • werasd says:

    Design is nice, but product useless.
    And when the battery is in use it’s covered up, so design doesn’t matter.

    how long does it take to read up battery on wiki?
    geez…. stop embarrassing yourselves so-called designers

  • Silky Johnson says:

    Wouldn't the lost capacity from the volume that the switch displaces coupled with the extra cost to manufacture negate the "conservative" idea that this design is intended to promote?
