How to check whether the voltage of a high-temperature battery is stable?

The voltage of a high-temperature battery can be affected by various factors, such as temperature, state of charge, and load. Therefore, it is recommended to measure the voltage under different conditions to ensure that the voltage is stable under different operating conditions.

To check whether the voltage of a high-temperature battery is stable, a multimeter can be used to measure the voltage of the battery under different conditions. Here are some steps you can follow:

After charging or discharging, let the battery rest for a few hours to stabilize it.

Set the multimeter to measure DC voltage and select a range suitable for the battery voltage. For example, if the battery voltage is 12V, set the multimeter to measure the DC voltage within the range of 0-20V.

Connect the red lead of the multimeter to the positive terminal of the battery and connect the black lead to the negative terminal.

Take a voltage reading and record it.

Repeat this measurement several times within a few minutes and record each reading.

Compare the readings to see if the voltage is stable or fluctuating. If the reading is relatively constant, the voltage is stable. If the reading changes significantly, the voltage is unstable.
