When the battery voltage is lower than VDET1 – VHYS1 and charger is removed, the EC9528A series can be released fromthis condition . Remark: Please contact our sales for the products with detection voltage value other than those specified above. Table2: Delay Time table Remark Please contact our sales office for the products with detection voltage value other than those specified above. |
