My evolv dna 250 says check battery when i use it.

[Sendhalp]

I was using this mod like  a month ago. I then stopped using for 1 month and didnt touch it. Now when i try to use it it dosent on so i went to buy new batteries as i thought my old ones were faulty. But now when i hold the button it just says check battery and i am unable to do anything . Btw i am using a macbook . Thank you.
