    At 1.5V the battery is defective.  New batteries are 3V and usually a little more than 3 volts.

    Please press the blue Accept as Solution button below if this post answers your question.

    Below 3.1 volts under load is dying battery.

    Below 2.0 volts is dead battery.

    DL2032 batteries are not expensive.
