Song Meter SM3BAT
  • Battery Specifications: The recorder uses four (4) standard D size disposable alkaline batteries or rechargeable NiMH batteries. Battery life can vary widely depending on the battery type, brand, charger, temperature, and other factors. The following battery life cycles are typical and assume 10-hour nights and nap mode activated for full spectrum:
    • Alkaline batteries (estimated 12,000 milliamp hours at 1.5V each):
      • Full spectrum on 1 channel: 18 nights
      • Full spectrum on 2 channels: 15 nights
      • Zero crossing on 1 channel: 20 nights
      • Zero crossing on 2 channels: 15 nights
    • NiMH batteries (estimated 10,000 milliamp hours at 1.2V each):
      • Full spectrum on 1 channel: 12 nights
      • Full spectrum on 2 channels: 10 nights
      • Zero crossing on 1 channel: 13 nights
      • Zero crossing on 2 channels: 10 nights

Memory Cards:

Song Meter SM3BAT
  • The four (4) memory card slots can be populated with at least one (1) and up to four (4) memory cards of assorted capacities. The device supports all class 4 or faster SDHC or SDXC cards.
  • Memory Sizes: Up to 2 terabytes (2048 gigabytes) supported total capacity using 256 GB SDXC memory cards for all four (4) memory slots. This is the maximum currently available; higher capacities may be available in the future.
  • Formats: FAT32 for SDHC or exFAT for SDXC
  • Compression typically increases effective capacity by 40%.
