How a Battery Works

When the battery is dead we get a lower voltage, this one reads 1.07V so it''s completely dead. However, sometimes we could still get a voltage of around 1.5V even if the battery is dead. To fully test the battery, we need to test it under a load condition to check if it''s still useful. For that we need a resistor. Test Battery
