Inverse current Lithium primary batteries are not rechargeable. Therefore, if there is a possibility of electric current flowing from the main power source to the battery, the circuit must include two suitable blocking diodes in series or one blocking diode and one protective resistor in series (refer to drawing in chapter SAFETY GUIDELINES) Use a silicium diode of small inverse current to prevent charging. 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 re-charge energy may harm the battery or reduce its performance. Example: A CR2450N battery with a nominal capacity of 540 mAh is expected to supply power for 5 years. The amount of tolerable re-charge energy is 5.4 mAh, corresponding to an inverse current of 0.123 µA for the total service life. Consequently, a blocking diode with an inverse current not greater than 0.1 µA should be selected. Please note that the inverse current of blocking diodes varies with temperature.http://www.renata. …esignersGuide-2011.pdf Стр. 39
