تنشيط بطارية 12 فولت ضعيفة وقياس الجهد الوهمى للبطارية l علاج مشكلة البطارية الجافة لا تقبل الشحن

Reviving a dead 12-volt battery and measuring its phantom voltage: We measure the battery voltage with a multimeter, setting the function switch to constant voltage, and record the reading. Then, we connect a 5-watt light bulb and measure the voltage again. If the first reading is slightly lower than the second, the battery voltage is real. If the difference is large, the battery voltage is phantom or false. If the voltage is low, we open the battery cover and add 10 ml of dilute nitric acid or hydrochloric acid. We charge the battery for 5 hours, then measure the voltage without the light bulb and again with the 5-watt bulb connected. We observe an improvement in the dry battery's voltage. Don't throw away your old motorcycle battery! Learn how to measure battery voltage. We also measure phantom battery voltage if the battery gives a reading but doesn't work, and learn how to revive a dead 12-volt battery. To repair and recharge a dead dry battery, we open the top battery cover, open each cell, add 5 ml of dilute nitric acid or hydrochloric acid, and charge the battery at the appropriate voltage for 5 continuous hours. We find that the battery accepts charging and the battery's amperage is determined.
