Hello everyone, I have purchased a red 100mw 650-658 focusable laser diode and i t says the current I need is 200mah. Honestly I don't even know what that means. The only baterys I have access to are normal batteries from companies like duracel,energizer and Panasonic.( AA,AAA,9V ect) . what batery and how many of them do you think I should use?
