a few battery questions Answered
i got 2 questions
1st. i was shopping at target today and noticed that the big energizer rechargeable "D" size batteries has the same mAh rating as the smaller "AA" rechargeable energizers i have at home (2500 mAh) can any one explain this?
2nd. i've seen some pics around the site of custom "D" sized "AA" battery holders that hold 4 "AA's" in a "D" sized space ( https://www.instructables.com/id/SA59T0CFB11L31B/ ), but i haven't seen any instructions on how to make them. can some one make an instructable about this? (preferably one that can be made to hook up the" AA's" in parallel)
