Forum:Special summoning

Hey i have a question and i need help ASAP. I am using my batteryman deck and my opponent activated mirror force while i had charger and two AA's on the field. I had an Industrial Strength in my hand. Can i use his affect to special summon him in my battle phase??

Also, if I have summoned batteryman industrial strength by his summoning conditions then he is sent to the graveyard, am i able to special summon him using battery charger or portable battery pack????
