I wasn’t aware that faster charging shortens lifetimes. Does that mean that (using completely made-up numbers) that a battery will reduce to 80% its initial cap

I wasn’t aware that faster charging shortens lifetimes. Does that mean that (using completely made-up numbers) that a battery will reduce to 80% its initial capacity after 10,000 slow charges, but after 10,000 fast charges its capacity would reduce to, say, 50%?
- userbinator 9y agoYou have the right idea, but your completely made-up numbers are not even close --- the standard is 80% capacity after 500 cycles at the normally specified (1C) charge rate. If my vague recollection of the last time I read about this is correct, at 2C (twice as fast), after 500 cycles the capacity remaining may be more like 20%. It's definitely nonlinear.
