I slm imagine a single cell not being harmed by 0 volts; a few other types of cells can survive this. The point of my comment was that just because the pack recharged and could start an ICE doesn’t mean it still has normal amphour capacity.

See Shelf Life page Indeed, it’s the only thing that ever has! I need to let Phoenix Contact know too. It’s not a matter of trust, Bill. The battery was at zero volts for about two weeks. Got it, continue to print. Or do the test yourself. Or, is the battery shipped in an “off” state, where the cells are in fact still charged but the BMS and output is off? Their charger won’t recharge a dead pack. Do you have any test data on this?
All other best offers will be declined!!!! That’s fact; confirmed by the data.

The A cells I have are indeed pretty well matched. You’re more familiar with these than I am, Davide. SOC curve was even flatter than A cells! To exit the OVP state, apply a load to discharge to the battery.
Mencken — Lee A. However, A M1 cells are different and have been shown to not only survive being discharged to 0, but actually have a lower internal resistance afterward. Not always, but typically. It really doesn’t matter because the cells are unharmed by going to zero volts.
Tiny reverse voltage makes tiny damage. Others have done it.

I believe it not because of their marketing; but because I have a couple dozen of them, and have tested them myself. In reply to this post by Bill Dube. Search everywhere only in this topic. Was there a BMS on that battery? Thu, 28 Jun They are not repeatable, scientific tests.
If it did, it’s a crappy design. I told them about your findings that they should be on the evdl. The results are all the same. The voltage only goes low at the very end of the SOC.
Very little increase in internal resistance over the bulk of the discharge. What are the facts? Lee, you are applying you many years of battery experience from other chemistries mistakenly to LiFePO4.
Where is the test data to show that cells were run down to 0 volts, and then tested for capacity, internal resistance, and cycle life? Beginning with the first product offering in the series, the ALM 12V7, A’s ALM batteries can be deployed as direct drop-in lead acid replacements or as the modular building block for larger systems. Did you have an ammeter in the battery? They are guys doing uncontrolled experiments, with no documentation, and simply saying what seemed to happen by 12f7.
Read more about the condition. By pressing ‘print’ allm you will print only current page. Back to home page Return to top. Weigh less than half of comparable lead acid batteries. I want to know why a new battery arrived dead.
Mouser had all these batteries came in from Phoenix Contactboxed up and ready to ship back since they all read 0V, some are already in transit. It is powered exclusively from the series string of cells it is monitoring.
One or more of the cells inside could easily be at zero volts, and you would never know the difference. ASystems has done extensive testing as well. Regardless, all cells will be very badly damaged by reverse voltage. Start of add to al layer. Not at all; I’m only poionting out that there will only be voltage after 3 years if the load on the cell for that entire time is essentially zero!
