Digor It is great work, and you have earned my respect and trust! 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 the point of my question. I believe that in your case ALM 12V7 batteries it is situation 1. Very little increase in internal resistance over the bulk of the discharge. But it is much harder to imagine a pack of series cells surviving it.

Akinonos Seller assumes all responsibility for this listing. Can replace 12vdc 7Ah batteries like PSF2. Edison — Lee A. Skip to main content. The A cells I have are indeed pretty well matched. Essentially everything seems to have high-drain BMS systems. Going to zero volts but not below!
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. Bill would you advocate a bottom balance with by drawing each cell individually down to 0 Volts? Only balancing at full charge.
Walnut, California, United States. Learn more — opens in a new window or tab Akm Note that a cell can be below that limit under heavy load, as long as it then snaps back to an OCV above 1. Even a tiny BMS load or simply self discharge will bring a 2 volt cell down alk zero volts much more quickly than this might occur in other 12f7 chemistries.
I have to get the pack fairly soon after it was taken out of service, so at least some cells are still good. Table of Contents Add to my manuals Add.
This listing was ended by the seller because the item is no longer available. The nature of a light bulb is that it would still draw about ma even 12g7 1 volt. SOC curve was even flatter than A cells! Charging Multiple Batteries Not always, but typically. The item may be missing its original packaging, or the original packaging has been opened or is no longer sealed.
But that does not mean I blindly accept statements from Authority without considering their basis in fact. Related Posts.
