Nursing camera batteries?

In the UK, a decent NiMH low drain rechargeable is about 10x the price
of a disposable for say 2000MaH. 1.2V for rechargeable, which affects
comparisons - I've not found it an issue in use.

Worth it to me, plus the relatively low waste. Although not of much
relevance to cameras nowadays ;-)

very relevant for grips, flashes, other accessories and even a couple
of cameras.

it's not a conflict, thus nothing to reconcile.

There was a time when you could be counted on to be helpful when asked
a straightforward question. Those days seem to have gone.

I have recently read, in conjunction with suspected battery problems
on a third generation iPad, that it is desirable to discharge to zero
once a month or so. The explanation is that it allows battery
management system in the iPad to recalibrate itself. The explanatikon
was minimal and I didn't understand it. Does it make sense, even if
only in terms of iPads?

it makes sense. what part did you not understand?

The part where it contradicts your advice "discharging them fully is a
very bad idea... "

it doesn't contradict it at all.

add that to the list of things you don't understand.

So, what practice do you follow? Do you never fully discharge your
batteries or do you preiodically fully discharge them?

this is not about me.

diversion attempt fail.

It was not an attempted diversion. It was an attempt to get your
advice.

which was already given and you obviously did not read.
it's also not my advice either, but that of battery technology itself.

Never mind ...

yep.

And the advice of device manufacturers is that for the sake of the
battery management it is necessary to run the battery down to zero
from time to time. It's not possible to fully reconcile the two
requirements. How should this conflict be dealt with?


If you are talking about NiMH, Since they do not have memory, you can
top them off for everyday purposes. However if you do a deep discharge a
d recharge once in a while, it will prolong the life of the batteries.

Thanks Peter. I will take your advice on this matter ahead of nospams.

no

every cycle wears it down a little.

Rather like trying to carry on a discussion with you. :-(

once again, you fail to understand something and blame others.

I can't say about Lion. But my statement was based upon research
conducted on NiMH batteries to be used for medical purposes. And yes
cycles do cause the cathode to wear down. But a a periodic total refresh
increases the life. You can research that for yourself.

1) Don't fully discharge you batteries, it's bad for them.

2) Unless you fully discharge your batteries from time to time they
are likely to not properly charged.

correct.

false. where did you get that idea?

and that wasn't the issue anyway.

See the paragraph at the head of this article.

yep

See also your comment which followed.

yep

What to do? What to do?

one thing would be to learn before spewing.
