The Power of Four

Quarter Block Battery divides the battery cell into four equally powerful pieces. Each piece screws onto the next, making them kinda modular. The purpose is to discard the empty quarter and replace it with a juiced-up one. In the long run, the cycle of replacing and using up all four quarters may prove to lengthen the original life of the battery. But I’m not so convinced about it. Nevertheless I think if we get our physics and chemistry right, we may have a winner in our hands.

    Would there be an indicator on each of these pieces? Would the energy not deplete evenly across all modules?

    This is simply not how batteries work at all. When you put them in series like this, the current flows through all of them and they are drained equally. If one cell in the series has less charge than the others, its “internal resistance” is higher and it can overheat and cause damage to the device. That’s why makers of battery devices tell you not to do that!

    Many devices already use multiple cells in series. They just have contacts, no screw connections. If you “designers” are going to do any kind of engineering design – which is what this is – you need to talk to an engineer, or even an engineering student!

    The problem with using batteries to the last of its energy is not that they cannot be stacked like this. In fact in mant applications many batteries are stacked inside the device. However it is not recommended to use batteries half-empty with full ones for other reasons.

    Well stated. Nuff said.


  • matt says:

    very poorly conceived. electricity will run and drain through all the contact points and show no preference to one quarter. add the carbon footprint of making 4 products where one will do is counter intuitive.

    this design is use best english 😀 yeay all your base belong to us

    Oh… It is very impressive what you explained. Thank you to let us know the knowledge that you have. I had thought it was a very good idea at all before i saw your comment. Somehow thanks

    I mean to Amanito

    I don’t think the idea is simply to let you stack batteries. If I understand the concept correctly, I think they’re trying to maximize residual charge. If it’s just one battery, then when it dips under the threshold of being able to charge the device, it may still have 10 or 20% of its charge, depending on the energy demands of the device. Currently, all of that goes to waste. The idea here is that by having other units in the group that are fully charged, you can drain a little more energy out of each individual unit.

    It’s an interesting idea to tackle this problem, but the big issue is that it requires you start with four batteries of unequal charge (or at least one unequal) to make good use of it so that one runs out before the others. And the dynamics of energy resistance when the batteries are in series isn’t addressed, either (as already mentioned). It’s a neat idea, though, and could have some potential!

    Alright then, Brian T. If you’re so good, you invent a new battery!
