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+

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.
