ALM 12V7 s-Series batteries have been tested to Don’t show me this message again. Now maybe it’s there; the EVDL search capabilities stink.

Don’t just say it that’s marketing. SOC curve 12v even flatter than A cells! So, I don’t want to purposely run any A cells dead without evidence that this is harmless. 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.

Hopefully that’s not a significant difference to matter. Yeah, the archives are a pain to use.
The A cells Apm have are indeed pretty well matched. The packs are designed to assume that they will never be left idle for more than a few months at a time, without being charged. Is it a marketing claim, or is there test data on it? I agree; but that’s irrelevant to the current discussion. Sign in for more lists. Multiple-address or CCed messages may be rejected.
Until then, it flies in the face of my experience with other lithium cells including LiFePO4. In general, Li-ion cells suffer irreversible chemical damage if their OCV drops below a give threshold 1. Since the goal of zlm that 12v battery was to test it under typical consumer use, I jump started the car with a fully-charged 12 volt lead-acid battery, just like a consumer might do. Lee, you are applying you many years of battery experience from other chemistries mistakenly to LiFePO4.
Learn more – opens in a new window or tab. I need to let Phoenix Contact know too.
TPKs will be completely shut off. The latter has real numbers, and sufficient information so one could duplicate the test to verify the results. Tiny reverse voltage makes tiny damage.
The breakdown voltage of DZ4 is about 1. Estimated on or before Fri. Got it, continue to print. 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? That is not a “tiny” load. Even a tiny BMS load or simply self discharge will bring a 2 volt cell down to zero volts much more quickly than this might occur in other battery chemistries.
Maybe 7 years ago? Learn more – opens in a new window or tab Postage: Going to zero volts but not below! But that doesn’t seem to be the case, because Phoenix Contact’s own charger doesn’t turn it on.
What are the facts? They are guys doing uncontrolled experiments, with no 12v77, and simply saying what seemed to happen by memory.
Some use a microcomputer, or various digital or analog hardware circuitry. We’ll have to get it elsewhere. But we really don’t know if that was the case or not.
These cells have a very slow self-discharge rate; I have A cells that have sat for over 3 years and are still above 3v.
Mencken — Lee A. Can replace 12vdc 7Ah batteries like PSF2.

If one cell goes dead, the BMS knows; but it also continues drawing its supply current from the whole series string. Comments to this Manuals Your Name. The pack was delivered dead. Charge Rate By Temperature For charge acceptance, do not exceed the limits specified. It really doesn’t matter because the cells are unharmed by going to zero volts. 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.
OK; the warm wire meant the current was “high”. Mon, 2 Jul If there is no test data, maybe I have to sacrifice some A cells to science. If you don’t have the data; say so. I remember it well, but a brief search of the archives did not turn it up. Five years and 60, miles later, that 12v LiFePO4 battery still working perfectly.
