• Samsung 543 NAND memory (SAMSUNG 543 K9W8G08U1M PCBO CAI643CA)
  • Memory datasheet - Pages upon pages of information on this memory chip
• Li-ion battery (PR-622020 5J0600021 I484ER01AI)
  • Not much is really known about this battery. In the DAH-1500 and DAH-1500s players, they use a cell battery, but the battery in this model is a bag-type. One DAH-1500i however did have a cell (a 180mAh), so the battery seems to vary per player. No idea about who makes this particular one.
  • Disassembling the DAH-1500i - Has battery specs as well as user contributions
