On my multimeter, the voltage readings get inaccurate over time due to battery discharge. My meters all use 9 volt batteries.

How can I tell when to change out the batteries?

Thanks.

Sounds like time to change the multimeter instead!

Have you tried one of the lithium rechageable PP3 / 6F22 , they have
inbuilt BMS which switches out the battery for protection when it gets
to about 6V. The EBL ones do this. C+
