Says dV/dt and monitors each cell.  Says charges 2000 ma (fairly fast) with one cell, and 500 ma with 8.  The Maha regulates current at each cell, individual settings from 200 ma to 2000 ma (but only for four cells).Sounds right to me too.  The special Eneloops are like double price for only a few percent more capacity.Two sets of white ones are double price too, but 200% more capacity.  It doesn't seem a big deal to swap them out quickly, as needed.  Recycle tells you when they are getting low.They simply don't risk overcharging, because they have to last for years.Possibly undercharging is the same thing, but the batteries also power the starting motor, so they save some for it.  In fact, on a Prius, the air conditioner and the water pump are also electric, running on the same batteries (the motor shuts off stopped at traffic lights, but the AC continue on).    It also has a smallish 12V car battery for lights and electronics (charged from the HV batteries), but importantly, that operates a relay to switch in the high voltage battery. When the 12V is dead, you jumper start it just to activate the relay to the real starter motor battery. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />The Prius is certainly not a muscle car, won't win any races, but performance seems extremely adequate to me.  Texas has 75 MPH limits on interstate highways, and it does it all day.   It does not have a shiftable transmission with gears, but has a ring gear setup that the computer controls. Driver only sees Drive and Reverse.I don't know. They show charge status, but capacity is not shown.The batteries are in steel case, 3 or 4 feet long, under the back seat. Basically they are D cell capacity, but are made square for packaging.  The assembly is said to cost over $2000 to replace. Junk yard batteries are popular in that event.I think it is just the capacity mah number that matters.  Capacity does decrease with age and use, but if it will still actually deliver 2000 mah, then it still does what it was spec'd to do.  Capacity does decrease with age and use.LOL.  I don't think I'm very special. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />   I'm just interested in how things actually work, where many don't care.  I feel at at disadvantage to those with the ability to turn out the special pictures.  The "art" aspect just seems not my thing.</blockquote>
