If you're new to AirPods, considering buying a pair, or just want to pick up some new tips.
Apple Changing iPod Battery Technology?
Danionics supplied polymer lithium-ion batteries for the current Apple iPod, but according to Niels Kryger Anderson, Danionics' managing director, Apple has now chosen a prismatic (fluid based) lithium-ion battery for upcoming iPods.
Implications/advantages of changing from polymer to fluid based Lithium ion based batteries is unclear.
Danionics was not the only supplier of iPod batteries, and in light of the recent iPod battery controversy, they note that Danionics iPod batteries should still perform at 80% of full capacity even after three years of extensive use.
