Hi
Anyone familiar with the Energiser CHDC-CA Battery Charger? That just
happens to be the model number of the one I have but very common all over
the place and just the typical AAA and AA battery charger. Charges 4 at a
time. It is timer operated meaning it operates for about 8.5 hours and shuts
off preventing over charging. The manual says it will charge 2650mah AA
batteries in 8.8 hours then shuts off automatically. I try to deplete the
batter as much as possible. The unit's output is 2.8v 360mh . Now I believe
also its max charge time is 8.5 hours or auto shuts off at 8.5 hours.
Now, my new batteries ni mh are 3000 mah . Now if you cross mulitply you end
up with a 10 hour charge time mathematically, that can be done, just charge
1.2 (or 1.5) hours longer and remember to stop it. But if you factor it
differently as the 3000mah divided by the 360 equals the 8.3 hours to
charge, not needing the additional charging.

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

I can contribute only a little: Ni-MH batteries and Ni-Cd batteries are
different as to how they take a charge. While many Ni-Cd's no longer
display a memory effect, some do. As far as I know, there's no memory
effect for Ni-MH. This means you need to treat each type differently.

Would I be out of line to ask you what kind of battery you use and then
narrow the discussion to that type?

Hi Sal

I bought the ones off ebay that came from hong kong in about two weeks.
Package of 24 aa batteries and aaa batteries. These are nickle metal
hidryde. There shouldn't be a memory like the cadnium ones. These are the
3000 mah batteries and just wondering about charging them with my older
battery charger that only explaines about the 2650, so I don't believe my
batteries are charging to full capacity. Not even close.

I have called almost every Henry's and the Energiser's tech line.

Now Energiser cannot advise anything, they only sell batteries up to 2500mah
and chargers to same. Now I imagine soon they will be selling 3000mah
batteries as Panasonic and so many other mfgs do already. The batter charger
I have is obsolete now, 2 years old and actually they still sell it at
Henrys.

So I suppose my options are to buy a battery charger that is smart charger
that measures through trickle the capacity of the charging battery and shuts
off when trickle gets low enough. Or, use this charger and after its 8.5
hour automatic shut off time to pull out then push back into wall plug to
add about 1.5 hours of charge and not forget or it will run the cycle of 8.5
more hours and dissapate heat or overcharge the batteries reducing their
life.

The batteries measure 1.38 to 1.39 volts after the 8.5 hour plus the extra
about 1.5 hours charge. They measure about 1.17volts when empty.

Whats a poor boy to do? Come on Dave, I know you know. And you know that I
know that you know that These are for that battery pack for the HT that I
use to measure the gnd radiation for my sauna rocks. Very important.

He's an idiot. He doesn't care that his posts are always off topic, and at least
some people doubt he even has a license. He clearly doesn't understand batteries
and charging them, nor much of anything else it seems. Just do what most people
do - ignore him.

Hi Robby
Thanks for the repy. I assure you I am not an idiot but can you tell me
about the batteries?

Maybe he needs the batteries for his sauna.

Hi David

Batteries for my sauna? Now I never thought about that. 6000 watts ? Now
that is awsome.

I am afraid that the gnd radiation from the granite rocks I used might
interfere with the pulse charging action of today's smart chargers.

But I wonder how many AA batteries would have to be used inline to deliver
6000 watts for about an hours sauna?

You tell me that David and I will tip my hat to ya.

Yep. I have one. Piece of junk. Works only with NiMH. It will kill
a NiCd battery and will overcharge a partly charged battery.
http://data.energizer.com/PDFs/chdc.pdf
"Best used with Energizer NiMH batteries."
Note that it's obsolete.

Now, my new batteries ni mh are 3000 mah.

Maybe, under ideal conditions and with a very small load. Otherwise,
I've never seen a 3000ma-hr battery.

I have a West Mtn Radio CBA-II battery analyzer:
http://www.westmountainradio.com/product_info.php?products_id=cba3&navcode=/cbaLink1
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:
http://802.11junk.com/jeffl/NiMH/
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).
