Читайте РТМ'ы. Например: Renata: "The total amount of recharge energy due to leakage by the blocking diodes should not exceed 1% of the battery's nominal capacity during its total service life. A higher input of recharge energy may harm the battery or reduce its performance."
Rayovac: "The diode used in a circuit design with a BR Lithium cell should minimize leakage to within 3% of the rated capacity of the cell over the lifetime of the cell's use."
Varta: "Underwriters Laboratories requires for lithium cells/batteries a circuit, which must contain a protective component to prevent charging. In case of diode failure a current limiting resistor must be chosen according to the values listed in Tab. 10." Для 2032 - в таблице приведено 5 мА макс.
