Battery knowledge · Capacity, energy, power and ratings
Continuous and peak current
The current a cell can supply indefinitely without exceeding its temperature limit, and the higher current it can supply for a stated few seconds. Peak ratings are only valid for the duration and starting temperature given.

Example
C-rate, current and duration
5 Ah × 1C = 5 A. Ideal duration: 1 h (60 min).
Voltage cutoff, losses, temperature and rate-dependent capacity are excluded.

A C-rate becomes an actual current only when capacity is known.
5 Ah × 1C = 5 A. Ideal duration: 1 h (60 min).
I = Q × C-rate; t_ideal = 1 / C-rate
Illustrative model. Voltage cutoff, losses, temperature and rate-dependent capacity are excluded.
Use in Lemonergy
Separate nameplate ratings from test results.
This is a reference concept. No executable Lemonergy block has been verified for this term.
