Capacitor
The capacitor recharge rate is a non-linear function—the rate at any given moment depends on how much energy is stored at that moment. Near zero and near full capacity, the recharge rate is very low, and it peaks at 25 percent. The important thing to remember is that the recharge rate declines dramatically once it falls below 25% of capacity.
