will they at least have 76 percent of charge?
Because this voltage is somekind of neutral voltage for the chemistry used and cells with this voltage age the less. There are two aging effects, if I recall right, one happen in lower voltages and one in upper voltage. Indicated voltage value is a compromise, sweet spot for longetivity.Many recommend, when storing cells for long periods, only charging them to ~3.7V-3.85V. I haven't heard an explanation for why, tho. But it sounds like OP is not storing cells so much as preparing them to be ready for use when needed, in a year if it takes that long.
