In their tech specs:

> Battery lifespan: Will last for approximately 500 cycles, 8 times/day measurements in normal temperatures of 77 °F (25 °C) when new battery fully charged

> Battery life: A typical user can expect to charge HeartGuide approximately 2-3 times per week, depending upon the frequency of use of HeartGuide’s features

500 cycles at 8 cycles per day. Does that not mean that they expect the battery will fail after 62 days?

No, by cycles they mean charge cycles. 2-3 times a week is 166-250 weeks. About 3-5 years of active use.

I read that as 500 / 2.5 per week -> 200 weeks -> 4ish year lifespan.
