Review on Dyson V8 Absolute: The Ultimate Cordless Vacuum for Effortless Cleaning by Ha Joon

After a year and a half, the period of work in turbo mode decreased to 2-3 minutes. After stopping in turbo mode, the battery controller needed to be reinitialized: connect the battery to the base for five seconds and everything works again. I ordered a new battery on Ali, everything works. There you can also take an additional bracket for brushes that did not fit into the regular storage, and filters. Now about the old battery. It turned out to be possible to disassemble it only destructively. The electrodes are soldered to the elements by spot welding, and the electrodes can only be removed from the controller board with a soldering iron. The elements showed themselves to be practically alive, i. E. at a discharge current of 400mA, their capacity is 2500 mAh each (there are six in total). The elements themselves are of an unusual size: two millimeters thicker than the standard 18650 and five millimeters longer. This makes it difficult to use them elsewhere after they stop supplying the current required for turbo mode. Which is disappointing. The elements are thought to have slightly different chemistry. Perhaps, but this does not prevent the use of standard Li-ion chargers. The Chinese sell batteries on standard 18650 cells. While I use this for a month, the flight is normal.
