Important Installation & Soldering Notes

  • Soldering Required: This internal battery uses bare pre-tinned wire leads and requires micro-soldering to the motherboard contacts. Observe polarity strictly: Red is Positive (+), Black is Negative (-).
  • Water Resistance Notice: Opening the Forerunner housing breaks the factory adhesive seal. We recommend cleaning the bezel edges thoroughly and applying fresh electronics-grade sealant upon reassembly. Battery replacement alone does not restore factory water resistance.
  • Professional Installation Recommended: If you are unfamiliar with delicate electronics disassembly or soldering, professional installation by an electronics repair technician is strongly advised.
