New Member needs help with Battery Test Readings

I am trying to sort out my drawerful of rechargeable Ni-MH batteries. I decided to use for the first time the Test function on my La Crosse BC-1000 charger. The results of my first foray are here:

These batteries are rated 2100 mAh. After the test finished, the charger indicated as follows for the four batteries:

1. 1713 mAh
2. 2.00 Ah
3. 2.02 Ah
4. 2.00 Ah

Why is the first reading in mAh but the other three in Ah? Are are four batteries shot? Or is #1 the only bad one?

Thanks!

Hmm, don’t know why my picture didn’t show up. I pasted this URL in the “Insert Image” dialog; Dropbox - File Deleted

The charger may have formatting settings that change at 2000 mAh, I wouldn’t sweat that. Next, I’d say to run them all again in the same slots now that they are all discharged. Then a third time in different slots. Average the values then compare.

The display screen appears to be only able to display a “1” on the first digit (cannot display a “2”), thus when it goes higher than 1999, it will become “blank-2.xx” display —- at least that’s my guess.

As the above mentions, try rotating the batteries and re-test in another slot (maybe mark them first) — it could be each slot just has a slightly different reading, or the first battery is slightly more degraded than the other 3 batteries, but 1700mAh seems to still be OK, just slightly degraded… (which may mean its internal resistance may have gone a bit higher too; but may need a different charger / device to check resistance, which is also another important characteristic to test for batteries, in addition to capacity test readout.).

Make yourself at home, HowieG!

There is a link in my signature on how to post pics on BLF.

Some people seem to have trouble posting pics from Dropbox.

I clicked on your link, then right clicked on your image and chose "open in new tab", then took that image's URL and that's what I posted.

Thanks everybody for your very helpful posts! Thanks, too, to racoon city for getting my picture up. I will check out your advice on posting pictures.

I do not see an image in your post, just an empty box

Maybe Dropbox doesn't play nice with BLF?

the link in post 2 works to show the image

copy image location works to post that image here (using insert image icon):

> Are are four batteries shot?
no

> Or is #1 the only bad one?
no

the rated capacity is 2100mAh (=2.1 Ah)
the tested capacity of 2.whatever is very close

the 1713mAh = 1.713Ah, and is 19% below new capacity, it might not last as long, but it is not “shot”

That copies the exact same URL that I used to post the image, by the way.

I think you copied the image, not the image address.

they are not the same, and your post does not include the insert image tags… (The ! at begin and end of the image address)

That's because I am using the Advanced Post Editor, and the "! trick" doesn't work with the Advanced Post Editor.

Also, the "! trick" is not required for the Simple Post Editor.

Im not using a trick… I used the Insert Image icon, which has the effect of framing the link that I got with copy image location, between ! !

anyway
I respect your efforts to help the OP with image posting… I hope he figures it out… it Can be done :slight_smile:

I am using Opera, which is similar to Chrome.

Copying image address gives you the exact same URL as my method that I described earlier (in Opera.)

It may be different for different browsers.

Okay, I didn't know that.

I thought that exclamation marks only show up if you type them.

...

Wow, this thread really got derailed.

I looked very closely at the image address you posted:

it is in no way identical to the image address I posted…

I dont know why

It does appear that your way of posting images does not use the ! marks, it uses a different code that says
<img src=

if it works for you, there is nothing wrong with doing it that way…

I hope the OP figured out whatever he needed to know :slight_smile:

Like I said before, I'm using Advanced Post Editor and you're using Simple Post Editor.

...

Which internet browser are you using?

I agree your post editor uses different codes

also agree different browsers pull different image addresses

here is the result using Safari, for my earlier post I used Firefox (both work):

I don't have Safari, but I confirm that Firefox gives a different URL than Opera.

So I learned a couple of different things about posting images on BLF today.
