What's the fastest way to discharge the internal rechargeable battery in 
a wireless USB keyboard?

The white keyboard in question has a type-C USB port for connection to a 
PC, and a USB dongle of course. It also has a switch to select wired 
(mis-lablled as "OFF"?) and wirelss mode (mis-labelled as "ON"?).

BTW, the keyboard in question has LEDs under all keycaps. You can choose 
light shows using hot keys.

Why would you want to discharge the battery? For battery life it's
best to leave it charged.  As regards risk I think it's trivial,
problems only tend to occur when charging or discharging the battery.

Long-term storage!! I dunno when I will or might use it again.

Battery life is not important.

You sure about that?

Isn't it safer to discharge all energy before
leaving or disposing of rechargeable batteries?

I indeed worries about fire risks storing stuffs
with internal rechargeable battery, notably
self ignition or spontaneous combusion without
flame nor heat. Think hot weather!!

I would just leave it in its "last used" state.

The last thing you want to do is to store it fully discharged - depending on the 
battery design, it may never recover from a full discharge.

Cheers,

As I said in the another reply, I don't care about the life of that 
stupid but dangerous rechargeable battery. :)

But is a fully discharged r.b. still a fire disk?

Will a fully discharged r.b. self ignite/explode/combust?

A fully discharged battery /may/ not be in a safe state.

Just remove the battery, dispose of it, and replace later (with a new cell) when 
required.

It's cleverly enclosed in a plastic casing! Any other way(s) to 
discharge it? Say, via the exposed Type-C USB port of the keyboard?

It's more likely the keyboard will take power over USB than supply power 
over USB ...

Why would you want/need to do that ?  What do you think (c|w)ould go wrong 
if you didn't ?

But the fastest way would be to open the keyboard, take some electrical wire 
and connect the positive and negative battery terminals.  Depending on the 
kind of battery it might cause sparking and a glowing, *very* hot battery 
though.  It might even explode. But hey, its fast. :-)

You mean when its "on" the wireless mode is active - regardles of if the (PC 
/ USB) connector is plugged in and its recharging the battery - and when its 
"off" the wireless doesn't work - even though it could still charge the 
battery - and its just a standard PC / USB keyboard ?

What do you think that the switches labeling should have said instead ?

Keyboard in question: Acer OKW132 mechanical keyboard

ON  - WiFi Active LED flashes. That keyboard is in wireless mode,
       I suppose.

OFF - WiFi Active LED no longer flashes. I suppose that means
       wired mode, and I need to plug in the USB cable from the PC.

Regardless of the state of the switch, the type-C cable always
charges the battery, as displayed by the battery LED.

I haven't had the time to open the keyboard, because you need
to unmount all Cherry switch first, nearly 80 of them.

Thats a description of what the switch (supposedly) does, not an answer to 
my question.

Also, that led is blinking as long as its in wireless mode ?   I would go 
crazy because of the distraction (I would either disconnect/remove the led 
or throw the whole keyboard out)

> I haven't had the time to open the keyboard, because you need

The last time I opened a keyboard I could just remove the plastic bottom 
shell and leave the actual keyboard (with its buttons) with the top shell. 
It might even just be a foil keyboard, with a small circuit-board located 
under the leds (the mechanics of the keys being a part of the top shell).

I don't mind flashing lights. You can turn your back or close your eye 
and eyelids to ignore it. It's just light.

Unless your brain is born with weaknesses that reacts crazily when 
seeing flashing lights, or hearing drum rolls. :)

Only cursed or conditioned persons or patients
have the problem you described? It reminded
them of muzzle flashes?

... which means whoever fired a weapons that
flashes? You are a gun owner and/or lover?

Okay... that's interesting, Your Honor. :)

Can you do it via its Type-C USB port?

Mr. Man-wai Chang,

> Can you do it via its Type-C USB port?

Definitily not.

There is a bit of electronics between the cables power-lines and the 
battery - to make sure that the battery doesn't load to fast and not gets 
over/under charged (both can kill a battery rather quickly), and also to 
make sure that when the connector pins *accidentily* gets short-circuited 
you don't end up with a laptop-bag or backpack bursting into flames (or just 
fries the keyboards electronics).

And for the record : you should *never* short-circuit a battery (or any 
power-source for that matter).

But as asked, why do you think you should discharge the keyboards battery to 
begin with ?

Because the circuit prevents discharging
via the USB-C port? So as not to affect
the charging process? :)

Just wanna stop using the wireless USB keyboard
in question, wrap it and put it back into the box.
Then stuff it somewhere fire-safe.

That's all. No evil ideas. Not trying to blow
up anything. Well...

Evil people might read this thread, sneak into
my home then steal my wirelss keyboard and
use it to do evil. Well.... I have lost many
things without me knowing it.

Just let it self discharge in storage. As long as it is in a cool 
environment with no risk of the battery being crashed, it will be fine.
Alternatively disassemble and dispose of the battery before storing.

So to quickly discharge a rechargeable battery, the only way is to 
extract the battery out of secuerd casing, and short its anode and 
cathode (which are protected by chips) with a fuse?

That's really tricky for babies and kids.

That explained why they make USB port's pin smaller, narrower, finer 
while increasing the power. :)
