SubjectIs my Apple wireless keyboard's battery life inaccurate?
Message-ID<VbCdnSMKhITuVifJnZ2dnUU7-SudnZ2d@earthlink.com>
Hello.

On my Mac mini (mid-2011) at work, I use a small Apple wireless 
(Bluetooth) keyboard (no keypad). For several weeks, its upgraded Mac OS 
X 10.9.5 (all and since 10.7.5) has been showing my battery life going 
down until 1% (14% was the warning one that alerted me, but I didn't 
change the battery yet). It has been stuck at 1% for several weeks so 
far and the keyboard still works fine. It seems like the battery power 
is inaccurate? Is there a way to get an accurate reading? I'll change 
its battery once the keyboard starts acting weird/odd. ;)

Thank you in advance. :)

I've never found it to be all that accurate, especially when using
rechargeable batteries. And I don't think it matters much anyway. When
the batteries die, you'll know it and you can replace them. Advanced
warning isn't important.

Rechargeable batteries. Hmm, I have no ideas if these recharges, but 
then I never tried recharging them. They were new when I installed them.

I would think one would know whether or not the batteries they purchased
are rechargeable at the time of purchase. It's pretty obvious.

You wouldn't want a battery to leak.

Deep discharge is damaging to rechargeables mounted in series.

What on Earth are you going on about? If the device powered by the
batteries stops working due to insufficient charge, then that is ample
notification that the batteries are dead and need to be replaced or
recharged. Having a battery strength monitor doesn't change this.

Batteries are rarely equally discharged towards the end, so there is a
risk of pole reversal in a serie of batteries.

actually they do unless one is defective.

that's only an issue in a battery pack.

I doubt that applies to standard AA(A) batteries. And I don't see how
this has much to do with Mac OS X's battery level indicator anyway.

it does if one battery prematurely fails, but since they're individual
battery cells, you can easily replace the defective one. 

the problem is in a battery *pack* where you can't get at the
individual cells. if one cell fails you have to toss the entire pack.

it doesn't.

I am saying that it is not worth the risk to disregard the low battery
warning.

In my experience, with well matched rechargeable batteries, the battery
indicator is dropping so quickly at that point that there is little to
be gained anyway.

If you are happy to kill rechargeable batteries early, go ahead.

You're talking nonsense. I've used low self-discharge NiMH rechargeable
batteries with Apple mice, track pads, and keyboards for many years, and
have *always* waited until the battery actually died to replace/recharge
them.  I'm still using the first set of batteries from 2009 are still
going strong. I use them daily with no problems what-so-ever.

When I wait for the periferal to stop working, I often have problems
with the recharge. One of the batteries will stop charging within the
first hour or two. Waiting a bit and putting it back in again resumes
charging. I take that as an indication that the battery had suffered
some slight abuse. I have seen this both with my old charger that I use
with non-LSD batteries and my new Apple charger that only works with LSD
batteries.

Perhaps your charger is less fussy.

it stopped charging because it was fully charged. an hour or two is
typically how long it takes. 

putting it back in will cause another charge cycle, and if the charger
does not sense a full charge, it's going to overcharge the battery
which is bad.

the charge protocol is the same for lsd or non-lsd nimh batteries.

perhaps you don't understand how rechargeable batteries work.

Your charger is not my charger. A full charge is 12 hours on my old
charger. The Apple charger is faster, but not that fast. Fast charging
degrades battery life.

The Apple charger refuses to charge non-LSD batteries.

Why don't you read up on battery chemistry and charging in stead of
making a fool of yourself.

i never said it was.

that's a very slow charger and likely a dumb charger that doesn't sense
when the battery is fully charged.

improper charging is what degrades battery life. 

fast charging when done properly does not make a significant difference
in battery life and the batteries are cheap anyway so it doesn't really
matter. 

*really* fast charging (i.e., 15 minutes) can shorten life but the
apple charger doesn't do that.

the problem is that there are a lot of cheap chargers that do not sense
a full charge and overcharge the battery, which is what kills them (and
potentially can cause a fire). 

the better chargers have end of charge detection and stop charging (or
reduce to a trickle).

bullshit.

first of all, the charge protocol is the same so there's no point in
that and second, there's no way for it to know the difference anyway.
lsd batteries have thicker layers inside for a lower self-discharge.
otherwise they're the same.

the apple charger (as will any good charger) may reject batteries
because they've degraded or are defective (or not rechargeable at all),
but that has nothing to do with lsd or non-lsd. nowhere in the manual
for the apple charger does it say only lsd is supported.

i know far more about batteries and how to properly charge them than
you do.

12 hours to charge is absurd. You had a sub-standard piece of crap
charger. And no, fast charging does not degrade battery life unless it
is STUPID fast charging. iOS devices are very smart about charging.

You don't know what you're talking about.

Battery level indicators are vague guesses at the best of times. They
can also easily be fooled by simple problems such as dirty contacts.

What are you talking about? You replace the batteries when they die, and
you recharge them while you put in your other rechargeable set. Repeat
every 6 months or so.
