I replaced the main battery in a Gen1 Prius. Fiddly. Had to get a strong buddy to help lift it in and out of the car, but we did it in a long weekend. A full set of ‘used but tested’ cells cost something like $750 but that was probably 8 years ago.
Is it really unclear? If you had never heard of a product, you would much less likely purchase it. If Coke stopped advertising today, they’d start a very slow but real loss of market to it’s competiton, be it Pepsi or whatever. Note that a LOT of advertising is not for you. It’s for the corporate buyer at name your favorite restaurant so that they think that they’ll get more consumers in the door because they have Coke products, as opposed to some other brand.
I’m still rocking my 3rd gen. The biggest problem is actually that my eyes are starting to have a heard time reading it in lower light. A little larger screen like on the newer models would be nice, but there’s not really any groundbreaking updates to drive me to upgrade. Battery life is still pretty good for a 6 ish year old Device.
Actually the low cost part of this was that they weren’t upgraded cells. Just tested-good cells from other battery packs. Most of the time it’s just a couple cells in the bigger battery that have issues, and they take those out of the pool and make a good amount of $$$ because we were required to send back all of our cells. Assuming that of the 26 (iirc) cells that 3 or 4 were bad that’s a big profit margin for sure. The car worked great after swapping them out.
