Hi,
I have a portable design which use 2x16 LCD. The whole boards required 50mA. Initially I use 2 CR2032 in palleral to supply 3 V to the board. However, the LCD starts flickering.
I use bench supply to develop the system and I didn't notice the problem. Only after I switch the design to battery supply, the board doesnt work.
The battery datasheet can be found here:

Please advise me what kind of battery I should use. Thanks!
