I don't think people would only charge when the battery runs out. More likely people would charge weekly, say on a weekend night or during their weekly WFH day or something like that. A 14-day battery life would then mean an average of 10.5 days of protection, which isn't too bad. > You can argue that you'd be more dilligent about recharging but I'd counter that at scale you'd be the outlier. I don't know about this. For bicycle users, charging their rechargeable headlights and taillights regularly (typically once weekly) is very much a habit already. This is just another thing to charge at the same time, which is a time they aren't riding their bicycle.
