Best optical mouse with long battery life?

K

kony

curious about what you do with them then...
drive them to another council ?


Many places in the US now have a core charge, where have to
pay a fee for the new battery and it gets refunded when you
turn in the old... thus the recycling is done profitably by
the battery seller.

Its no big deal, just neutralise it and its fine.


That's a rather silly argument.

What IS a big deal if you just neutralize it?

Atom bomb? No big deal.
Deadly nerve toxin? No big deal, just neutralize it.
Bitchy wife? No big deal, neutralize.
Firebreathing dragon? I thought you neutralized her!

No, it is reasonably long enough that it's no big deal to
swap out a RECHARGEABLE battery.

In other words, what do we care how long each pair lasts
when rechargeable, so long as you don't consider it a PITA
to swap out cells every other day?



yes but they necessarily make tradeoffs to get that longer
life. Sometimes they use a less bright LED, or more
aggressive sleep mode where every time the mouse sits for a
tiny bit of time it has a minor lag when you move it again.

I don't notice any trade-offs... it works flawlessly.
Sleep-mode ? I don't notice it sleeping at all... if it does, it wakes
up REAL fast.
So: less energy consumption with same or better performance is ALWAYS
good

what he meant is, to add acid to the hydroxide. you then get water and
a salt: if you would add hydrochloric acid, you would have water and
potash (which again is used to kill people by injection: heart
failure).

Nevertheless: I would not hammer the cells open to get at the
hydroxide. That is dangerous stuff, it dissolves skin tissue (like
your cornea) in a BAAAAAD way. Worse than strong acids.
Used to get drainpipe going again.
I once got a drop of NaOH (comparable) on my thick woolen SOCK. You
can still see the dent in my FOOT.

So, contrary to Rods advice: do not mess with things you don't know
about.

We'll see...

Pity you cant neutralise heavy metals, child.
Atom bomb? No big deal.

Wrong, as always. You've gotta problem with
the radioactivity that cant be 'neutralised', child.
Deadly nerve toxin? No big deal, just neutralize it.

Even someone as stupid as you should be able to work out the difference
between a nerve toxin and heavy metals, if someone was actually stupid
enough to lend you a seeing eye dog and a white cane, child.
Bitchy wife? No big deal, neutralize.

Easier said than done, child.
Firebreathing dragon? I thought you neutralized her!

Pathetic, really.

It might just be completely trivial to neutralise KOH, but not that
easy with a hell of a lot of other stuff like heavy metals, child.

Nope, KCl. Potash is K2CO3
(which again is used to kill people by injection: heart failure).
Nope.

Nevertheless: I would not hammer the cells open to get at the hydroxide.
That is dangerous stuff, it dissolves skin tissue (like your cornea) in a BAAAAAD way.

Completely trivial to ensure that it doesnt do that.
Worse than strong acids.

Nope, try conc nitric some time.
Used to get drainpipe going again.

Nope, that is NaOH.
I once got a drop of NaOH (comparable)

Nope, quite different, actually.

Clearly applys to you in spades.

Nope, KCl. Potash is K2CO3
Sorry: that is CARBONATE of potash.
However: "potash" is used with various adjectives. KOH would be called
caustic potash too.
yep


Completely trivial to ensure that it doesnt do that.

Yes, and dangerous too.
Nope, try conc nitric some time.

yep: caustic stuff is much faster...
Nope, that is NaOH.

yep, but NaOH too. (I even was sold concentrated H2SO4 to do that.
melted my PVC pipes real quick. but that is another story).
Nope, quite different, actually.

nope: different AND comparable.
Try that with conc nitric acid some time.

I would have had time to rinse. But i have to take the word of my
local chemistry expert on that. Ain't gonna test it.
Must admit that a welding torch might be even faster...

depends on what you would like to use as a definition of
"neutralize".

Neutralize a bankrobber/terrorist ? kill
Neutralize a fragmentation bomb ? defuse
neutralize an acid/hydroxide ? bring pH to 7
neutralize heavy metal ? put it in a closed container/chemical
reaction to safer molecule

Generally it would mean "change extreme behavior" or something like
that...

any way, I would not tell MY to open up a KOH container...trivial or
not.

That is getting too anal.


Thats overstated too, the small volume of rechargeables
is a trivial problem compared with car batterys.



See above.




There isnt any point in getting all anal with the very
low volume of rechargeables that do get disposed of.

Wrong. Especially when they contain things like nickel and cadmium.
Contamination of ground water with heavy metals is a big problem and I
seriously doubt the volume is as low as you assume it is.

ultimately, EVERY battery gets disposed of somehow. So check
production statistics.... then you know...

If it suits your needs, great. Others may be able to notice
the difference though, and will want something else.

Neutralize can have more than one meaning.

Neutralize the threat from the (thing) for example.

it doesn't change the questionable judgement you show,
suggesting it is reasonable to neutralize SLA batteries.
What would you do THEN? Throw away that large bit of lead
too? Think a bit before making such suggestions, the old
batteries should not be neutralized, they should be taken to
a proper recycling center as-is. Anything else is
problematic in one or more ways for no good reason.

Neither of which are a particularly important problem
environmentally with the tiny amount seen with the very
small number of rechargables that do get disposed of.

Not from the small number of rechargables that do get disposed of.
and I seriously doubt the volume is as low as you assume it is.

Corse it is when compared with the volume of non
rechargeables and stuff like lead acid batterys disposed of.

Even you should have noticed the significant
differences in volume of the heavy metals involved.

Nope. The word potash used alone refers to what
gets produced with relatively primitive processes.

And neither is produced when KOH is neutralised with HCl

Potash isnt.

I dont need to take anyone's word on it, I've seen one fool do it.

No might be about it.

There is no definition that applys with heavy
metals, they cant be 'neutralised'
Neutralize a bankrobber/terrorist ? kill

neutralize an acid/hydroxide ? bring pH to 7
neutralize heavy metal ? put it in a closed container/chemical
reaction to safer molecule

Nope. There is no 'extreme behaviour' when weak acids and alkalies
are neutralised, most obviously with vinegar and baking soda etc.
or something like that...
any way, I would not tell MY to open up a KOH container...trivial or not.

Alkaline batterys are a different matter entirely, no need
to start hyperventilating about them any time soon.

If they were a serious health risk, they'd have huge warnings on them.

They dont for a reason.

It tracks badly, like a 4 year old Logitech I used to have.
Mouse technology is so much better than that today. If I
had one and hadn't a different mouse for my laptop yet I'd
probably reserve it for that use, it's not a horrible mouse,
just nowhere near as good as many current mice.

Hmmm...it is a "terrible" mouse, but not a "horrible" one?

According to my thesaurus:

Main Entry: terrible
Part of Speech: adjective
Definition: horrible

Almost seems contradictory. <g>

Lead acid storage batteries are, and have always been recyclable. They seldom
wind up in landfill sites. In fact The typical new lead-acid battery contains
60 to 80 percent recycled lead and plastic.

Not on a tiny AA or AAA battery you can't...
They dont for a reason.

they are taken in by recyclers just because of health risk. the zinc
and manganese oxide are not much trouble. It 's the KOH that they want
off the streets.
You won't DIE when using pliers on them, but still... NOT my kids...

Not in the context it was used in it doesnt.

Never ever did anything even remotely resembling anything like that.

I clearly JUST said that the KOH he was hyperventilating
about isnt a problem, its completey trivial to neutralise that
and end up with something environmentally innoccuous.
What would you do THEN? Throw away that large bit of lead too?

There is no lead in the alkaline batterys being discussed.
Think a bit before making such suggestions,

Go and **** yourself.
the old batteries should not be neutralized, they
should be taken to a proper recycling center as-is.

Wrong with the alkalines being discussed.
