2 min charging time on a 2016 coin cell. Nice.
The fact they are in 2016 Coin Cells tells me they are no where near market ready with the standard coin cell of a 2032(or even the cr123 is a crucial design and test). I have not seen a cr2016 coin cell in a circuit design in my lifetime and there is only one time I can remember seeing a cr2016 in a toy.
I am going back to that charge time, if 2 min is the charge time on a 2016 coin cell, I would love to see the charge time on a 18650 G+Al Battery. Those stats are very important to EV’s if GMGMF is going to be battery manufacture to reckon with.
18650 takes about 3 hours to charge, but we are talking about a 3000mAh battery, G+Al is(1.8v to 2.0v cutoff) 150mAh. So the 18650 is 20x the power of the coin cell, in theory I would say that the 2 minutes times the 20 is 40 Minutes of total charge time for a 18650 G+Al battery. Theory as we know doesn’t always prove to be the exact real world expectations of the product in physical form.
Here is the next question that arises, I pointed out energy density previously and if the G+Al is going to be competitive with lithium, they have to reduce their footprint on their batteries. The energy density of lithium to G+Al was a 1000% difference. Meaning lithium packs more of a punch in a smaller space. May take more time to charge, but to Product Managers retail space and product design have to be symbiotic. And I have a hunch, lithium is chosen, lighter and smaller.
They have to cut ties with 2016 designing and testing and get to the heart of battery usage 2032. They are wasting precious time on design and testing. Just an FYI, just because you perfected the 2016 platform doesn’t mean it will behave the same on the 2032 platform. No one battery is a like, they behave different. Sure you put in double A’s and it does what you want but why did the last set work longer/shorter than this set?!?!
At my last job, I told them about batteries having this mysterious side to them, they have this mystery box of unknown power. They laughed at me, 8 months later they came back to me wanting to know more about this mystery box. I still laugh to this day about that product launch, 2 years later and $2.5 million behind budget. Glad we were able to get it launched though.
