I currently use a Dell optical mouse that came with my Dell WinXP
media center. Unfortunately the mouse uses up batteries very fast! My
computer is left on 24 hours day, and usually the mouse needs two new
AA batteries every 2 - 3 weeks.
A mouse with rechargeable batteries would be a better solution, but is
there not an optical mouse available that uses regular batteries but
doesn't drain them so fast?
As an environmentally-conscious type of person, I don't use anything *BUT*
premium-grade rechargeables. Why? Well, batteries contain sulphuric acid
(even the rechargeable ones, I believe - though someone correct me on that if
I'm wrong) which is a major pollutant, especially if it leaks into waterways
and it's the type of poison that accumulates. Say a stork eats a fish that
has died of sulphuric acid poisoning. If it eats enough of them it, too,
will die. If a scavenger then eats the stork, it may very well succumb, too.
And it's not just fish in rivers. H2SO4 is a very strong acid (I believe its
pH to be 1 or 2). Imagine what an acid that strong would do to *anything*.
It's also a major contributor to acid rain (the other being carbonic acid).
Now, although rechargeable batteries may also contain H2SO4, decent ones will
replace at least 100 non-rechargeables, ergo that's 100 times less H2SO4 in
landfill (okay, I'm aware that facilities exist for the safe disposal of
batteries at most council tips, but you have to take them there yourself and
many people will just put batteries in with the normal rubbish, which then,
probably, will end up on a landfill site somewhere. I actually think councils
should provide 'battery boxes' for old general-purpose batteries which would
then be collected once a month. I think that some councils will pick up - and
dispose of - old car batteries for you (but ours doesn't)).
Then there's the financial aspect. A pack of 4 AA Duracell batteries (the
bog-standard ones, I'm not talking about the M3 variant) will set you back
about £4, i.e. £1 per battery. Now, I think I paid £10 for a 4-pack of very
decent rechargeables not that long ago. Okay, the initial outlay is 2.5 times
as much, but look at the longer-term picture. By buying the rechargeables,
not only will you be doing the environment a favour, but you'll have saved
yourself £90.
Now, isn't that something worth thinking about?
