Part supplier sources maintained Wednesday that Apple had recently been pushed into switching battery supply for the iPad 2. Apple moved some of its orders from Simplo to Dynapack at the end of September after Simplo's eastern China plant produced some leak-prone lithium-polymer packs, according to Digitimes. Apple's use of safer lithium-polymer batteries kept them from showstopper fires, but the recharging problems were enough to require better.
