Sub For 1-AA Battery?

Hi all~ Years ago, I used to use the Audio Technica AT813 mics, and instead of the 1 AA, I used to put in 2 smaller batteries that would slightly increase the voltage & improve performance. Does anyone recall what battery that might have been? BTW, because if the higher voltage, I was instructed to remove them when not in use...?
Thanks & be well~
