Turn regular non-rechargeable batteries into rechargeable
ones.
This device checks the heat and stops the current if
overheated. Also has a cooling device so that can achieve
better effectiveness.
The device is surrounded by a lightweight but durable
material which will catch the energy
and distribute it, in case
of an exploding battery.
Of course it will have a display with an estimate of the
battery's power upon insertion and time expected till filling.

Watts Clever Battery Charger Even Works With Non-Rechargeable Battery [Loris, Apr 24 2013]

How does this device and the other device work? |
|
| |
A long time ago, I saw adverts for chargers that "work
even with non-rechargeable batteries". |
|
| |
So, presumably then, the problem is that normal
batteries either overheat or accumulate gas if you
try to recharge them? |
|
| |
They were taken off the shelf after explosions
occurred. |
|
| |
So my idea checks the heat, --woops, read
carefully the specs on the link, their's does too...
and stops the recharging
if things start going wrong. |
|
| |
So what makes it special is that it is enclosed in a
special cover that will safely absorb the energy in
case of an explosion. |
|
| |
Could the e - forget it, i have an idea. |
|
| |
It does not address the fact that under recharging a paste battery inevitably produces small bubbles of h2 gas, which are in turn trapped in the battery and can cause the battery to rupture or explode if it becomes shorted in latter applications. Thus the danger of a battery failure increases even after the charging process. It is perfectly possible to recharge a non-rechargable battery, but this process will result in a battery that could be significantly more likely to suffer a critical failure. |

A "rechargeable" battery, in general, is one in which the
chemical reaction which occurs on discharge is simply
reversed when the electromotive force is applied back to
the battery in the other direction. |
|
| |
A "non-rechargeable" battery operates via a chemical
reaction which cannot be reversed simply by pushing the
electricity back through it. Perhaps some of the reaction
products escape, or diffuse away from the electrodes, or
any of a number of other things can make the the
reaction "non-reversible" (q.G.) The product of the
attempt can be a partial-charged battery, a hot battery,
a leaky battery, a bomb, a flaming battery, a short
circuit... Failure modes abound. And predominate. |
