Title: a plotting of output from a AA battery with Mooshimeter
Post by: Westbranch on December 19, 2015, 04:10:33 PM
Wish we could get these types of graphs for our batteries, tells a good story... reminds me of those for LiFePO4 batteries discharge profile

Should be able to do that with the Classic and WB Jr.  Just a Simple Matter Of Programming  (SMOP)

Right you are boB....

I was thinking about their usefulness if we had those before purchase if available...

What sort of batteries are you looking for profile graphs of, WB?

Hi Clod, the ones showing in my sig line..  there is nowt available by the maker... and I have had one unintended deeeep discharge one one of my banks but it appears to have recovered.. just curious to see what the maker 'planned' as a recoverable DOD

Ahh, yes. Makes sense. :)  It seems to me that many battery types can recover so long as you do not push them into reverse. The idea of keeping them all balanced at the low point to have them all be dead at the same time, thus not killing each other.

Isn't a battery by default when it is first made near a zero charge? Then energy added to it. It would suggest that a very small amount of ~100%DOD are not detrimental. However, relying on that would be.

Or have I it wrong and that even post manufacturer due to dissimular metals and electrolite there is still a potential? I can see that being the case with an electrolitic battery such as AGM/ PB cells but for lithiums ? Hmm. It is a different process entirely. One of inter-chelation of atoms while another being strictly a chemical exchange.

As an aside, I have a Mooshimeter. It's an excellent device.  Accurate, hands free mutlimeter - can measure power (simultaneous Volts/Amps) and can do remote logging with it.  Very useful for RE systems among other things. Good support from the developer as well.

Costly?

$120 (https://moosh.im/product/mooshimeter/).  Includes case and leads. Free IOS and Android apps for it. 

A bargain IMO.
