  Thanks for sharing this.

  It looks like the cutoff voltage for LiFePO4, the minimum voltage after which there should be a total power cutoff is around 2.8V. Discharging further is equal to more or less serious, but always, damage to the cell. It also looks like the effects of such over discharge might be less serious for LiFePO4 than it is for Li-Ion cells. However… doesn’t this 1500$ device have a Battery Management System, BMS, a small circuit to implement the cutoff voltage? What the hell?

  0.9V on a lithium cell? And it still charged? …

  I wouldn’t be able to sleep under the same roof with these recovered cells charged again, being scared they could catch fire.

  Next time just replace them, maybe upgrading total capacity if you happen to open the device anyway.

  You are totally right. Median and average alone mean shit without each other and without deviation, and such article like this is considered by me a manipulation without further correctness check. The same shit is with journalists confuckulating percentages with percentage points.

  In over 10 years I was made aware of these practices by my university professor I haven’t found a single article which got that right.

  Well, this is exactly what mathematicians do.

  Why downvotes? They are both right, with an exception of MacBooks. Otherwise, you are limited by use cases predicted by the manufacturer, even if it “just works”.

  I use both iPhone and MacBook, with the latter mostly as a Unix that, again, “just works”, but I can even go as far as compile whole GNU userspace natively with Gentoo Prefix (one of many options).

  Brother for life. You bet it. I got one toner refill for like $6 for Brother laser printer which is happily chugging along with factory installed drum after 2600 pages printed during over 6 year period. No DRM, no driver drama, and you know what happens to jet printers with such sporadic usage.

  Hah look at the downvotes, you can’t have civilized discussion these days.

  Your last paragraph and my last sentence is the whole culprit for me. The money I have to pay here for good heat pump with COP 2 at -30 and the associated electric bills have currently no chance here to ever be cheaper than burning gas either nor more friendly for the climate where my government burns coal to produce electricity.

  And no, I cannot install enough solar to power this heat pump in the winter or offset the cost of electricity during summer (inverters already turn off in the summer, no electricity is produced as too many neighbors have solar and voltage rises above shutdown threshold in the grid)

• ⁨Comment⁩ on ⁨Oxford study proves heat pumps triumph over fossil fuels in the cold⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  The COP coefficient falls down drastically to 1 as soon as temperature drops below -5C and they basically start working as an electric heater. It wouldn’t be a problem if I wasn’t living in a country with the most expensive electricity in Europe which is produced mainly from coal…
