I have a West Mtn Radio CBA-II battery analyzer:

I've tested a few of the flea market NiMH batteries claiming to be
3000ma-hr and found them lacking. I'll post the graphs (if I can find
them).

Incidentally, did you know that it requires one or two initial charge
cycles to get an NiMH battery up to full capacity? I didn't believe
it so I ran some tests:

It's not much, but it's certainly real. Note that the load was on the
high side at 1C resulting in measured battery capacity lower than
claimed. This is normal, but I was in a hurry.

Anyone have experience with these? Just typical rechargable batteries for
camera. Any tips on charging these properly?

If it's only run by a timer, it's a piece of junk. It probably
assumes that the batteries to be charged are totally discharged, and
after 8.5 hrs of charging, will be fully charged. That sucks because
a half charged battery will be overcharged by that method. If the
batteries get warm, they're being overcharged.

What it should do is look for a decrease in terminal voltage,
indicating EOC (end of charge).

Hi Jeff, Thanks for the info. That pdf is where I learned that this charger
only runs for 8.5 hours and it recommends stopping at certain times for
certain mah batteries. It works nice for me because I can plug it into 120
or 220 where ever I am. And my batteries are always depleted before I charge
them.
Only problem is that I bought the battery pack for my ht and it takes 10 but
charger only charges 4.

http://www.ebay.com/itm/160593039544... 4.m1497.l2649

But the batteries I bought were these ones

http://www.ebay.com/itm/New-Camera-R...item4cf59ac314

I have bought these batteries before for my home phones and they work great.
The home phones batteries lasts for weeks without putting back on the
charger. I guess I am used to the ni cads because I like to deplete 100%,
just a habit.

But that charger pumps out 360 ma at 2.8v and if I do the math that tells me
they charge completely at 8.3 hours. That falls within the operating range
of the charger. Why does the instructions say 8.5 hours for the 2650 mah
battery for full charge? Is the charger that innefficient that there is 20%
loss? Or were the first couple charges not effective like you said. This is
the third charge and the HT emptied quickly. Plus I am now pulling the
charger and plugging in again only for about 1.5 hours. Would you recommend
that?

Since it is for my HT I would only assume it qualifies for antenna subject,

I am surprised that absolutely none of the dozen local electronic stores and
box stores had any idea what I was talking about, even the energizer tech
support line were scratching their heads, yet seems so logical a question
for me because I want those battery lives to last as long as possible and
charging is the answer there. Hense my original question about the charger.

These batteries measure all 1.38 volts when charged pretty consistantly and
1.17v when depleted, other than that I cannot measure the efficiency of the
charger to predict time of charge, according to the manufacture it should be
9.9 hours, according to the math 3000mha devided by 360 ma of the unit says
8.3 hours to charge full capacity.

Which is it?

I have a pretty good question here Mark, Robby, just because you don't know
the answer, don't make it look like you are smarter than me.

So Robby, you called me an idiot, yet I asked the question, and you haven't
any idea about the question. Same to you Mark. Just because you don't know
about rechargeable AA batteries, keep your ignorance to yourselves. I am
asking, and just because you don't know a thing about AA batteries, well, I
recommend either you asking or take a course.

The best thing for you two to do is when someone asks a question, and you
don't know the answer, haven't even a clue. Just hang on the side there and
watch (or listen) and you will learn also.

I think I may have answered it myself anyway, I am charging for a full
charge then about 15% more which re-sets the timer. And I also agree with
Jeff, the first few charges in their genisis are important.

So there you go Mark and Robby, see you learned something here today, you
can thank me. Why not thank someone who helps you learn, instead you call
them names, fling some mud.

Good luck

Hi guys

I think i have answered my own question again. Jeff you are right, the
charger I have is lower end and while good for traveling, it is lmited.

The older chargers aren't suitable for the newer batteries. With 3000 and
3500 mah batteries out now and these older chargers are only good for lower
amp hour batteries, you need the smart chargers. Here is one I am going to
try and will give you all a report later on as to its workability.


http://www.thomasdistributing.com/Ac...er_p_3012.html


If anyone has comments on this charger, I sure would like to hear. Seems
like it is a good smart charger but only runs up to 2900 mah so my batteries
that are 3000 mah may work well.

I didn't say it was limited. I said it was a piece of junk. I have
mine in my digital camera bag, for use only in emergencies.

My favorite cheap NiMH AA charger is another piece of junk that I
picked up at Radio Shock. Model 23-1305.
http://www.digicircle.com/item_desc.php?make=RadioShack&model=23-1305%2030-Minute%20Battery%20Charger&id=29506745
Works with AA NiMH only, charges in 30 mins, and hasn't killed any
cells, yet. It's smart enough to recognize that a cell is partly or
fully charged. I erratically retest my NiMH batteries for capacity
loss after charging with my CMA-II battery analyzer. No problems yet.

If you want to do something better, try converting your HT battery
pack to Li-Ion. You'll need an external Li-Ion charger and some
mechanical work, but the resultant huge increase in capacity will be
worthwhile. I've done this for a few home toys (flashlights, alarm
system, battery backup, etc) but have not tried it with an HT. See
model airplane and model auto sites for chargers.

If not, go shopping for an NiMH "smart" charger.

If someone wants to answer an off topic post, that's is up to them, I, and
several others don't encourage them by refusing to answer. Your logic(?) is
flawed if you think owning an HT that has an antenna means your battery
questions are relevant - they are not. That same logic would give you or anyone
else the right to ask about an automobile engine simply because the car has an
antenna, be it 10, 6 or 2 meter, it doesn't make it on topic. Only an idiot
wouldn't understand that.

What happened to Hams? Used to be such a knowledgeable bunch, still are
however there are lots who are wanna bees and you can patrol the newsgroups
looking for whatever.

When you become one, be sure to LEARN about the basics, or at least learn where
to go to be on topic. A good general information place to start would be
alt.ham.radio but be forewarned, don't ask about your sauna rocks, or any other
non-amateur radio related subject, it will only give you away as an idiot or
troll. Your "handle" seems appropriate at least. If you are going to insist you
are a licensed ham, prove it first. You have certainly provided enough
information to prove you aren't. One more time, if your question doesn't relate
to the title of the group, don't bother asking there, go to any group that is
simply a ham radio group, not an antenna group, not a digital group, nor any
other group your question directly relates to, not because you happen to have an
antenna in the next room, or a modem packed away in a box somewhere.

I have a pretty good question here Mark, Robby, just because you don't know
the answer, don't make it look like you are smarter than me.

Your attempt to egg us on, well, I can only speak for myself at least, will not
work. I can't speak for Mark, but I will only state that I most assuredly know
about this topic, and let me add, your musings are so far off base, they have
been entertaining, if nothing else. I, like many, do not encourage repeated
abuse by people like yourself. People who, in spite of being told repeatedly
that your posts are off topic in this group, continue to IGNORE those who tried
to help you by pointing you to one of the other groups where your ignorance will
be hidden from view by virtue of not being off topic. If you continue to ignore
this fact, then you are rightly labeled as ignorant. I can only surmise you are
either a politician, or a salesman of some sort. A car salesman perhaps? Or
maybe a tire, (or do you spell it tyre there) jockey? Oh, and I don't have to
be ignorant of batteries, (I am quite knowledgeable in fact) to make it look
like I'm smarter than you are, you are proving that just fine all by yourself
thank you. You would have been much better off not responding to my post.

So Robby, you called me an idiot, yet I asked the question, and you haven't
any idea about the question. Same to you Mark. Just because you don't know
about rechargeable AA batteries, keep your ignorance to yourselves. I am
asking, and just because you don't know a thing about AA batteries, well, I
recommend either you asking or take a course.

Again, your crude attempt to provoke an answer out of me at least won't work.
I'll leave it to Mark to give you his response, if he even bothers to give you
one.

Speaking of responses, this will be my last, regardless of how much you try to
provoke one. I can only speak for myself, but I would hope everyone else here
ignores your future off topic posts, as amusing as they might be, they have no
place here. If you feel this is unfair, comment about it in alt.ham.radio, or
better yet, find a Canadian amateur radio group, perhaps they will have more lax
rules.

Hi Tom

Thanks for the comment. But I respectully disagree. While I have qso with
some of (in my opinion) the most intelligent people I can talk with on the
HF and VHF bands. Especially on the HF bands because you must identify
yourself regularly. However on the internet I find when you have a
conversation with someone they are always asking you what color underwear
you are wearing or something stupid like that. Not the same as on my HF
rigs. I prefer the HF to the internet anyday. However, I do use this group
as a resource for information, my server doesn't give me many newsgroups
related to the questions I have asked. But if I ask the question, I get 10
responses, and half of them are flinging mud at me, the other half some
useful information I feel good. And I am thankful. And I still say there is
a lot of intelligence in here, and I love it.

I learned more about batteries this last week and today's way of dealing
with them and I know many readers here did also. Big win win. Crazy thing
is, I just refreshed my memory as I learned all this long ago, but forgot
it. Damn for braincell degeneration. Anyone recommend anything for that?
Scotch and vodka and vitamin b doesn't work. I can contest to that.

But back to your opinion of identifying yourself each time, and identifying
yourself entirely. Remember those 50% who fling mud? Well they are capable
of anything these days and anonamously throwing rocks through your windows
late at night is possible with some of these wackos. So the reason some
don't identify themselves all the time may not be because they are not hams,
they just want annonamity (spelling?) to keep their guard up as this
internet really brings out the worst in some people.
