Key Features

• Samsung Grade A+ 18650 Cells: Premium Korean-manufactured lithium cells provide stable 11.1V output with minimal voltage sag, ensuring precise infusion rate delivery across the full charge cycle — critical for vasoactive drugs and high-alert medications.
• Ultra-Compact Form Factor: At just 33 x 27.59 x 10.15mm and 147g, this battery maintains the syringe pump's lightweight portability, ideal for space-constrained ICU bed stations and intra-hospital transport scenarios.
• Reliable Infusion Power: 2600mAh capacity delivers extended runtime for continuous syringe pump operation, supporting long-duration infusions of sedatives, insulin, chemotherapy agents, and parenteral nutrition.
• Zero Memory Effect: Li-ion chemistry supports partial discharge and frequent top-up charging without capacity degradation — perfectly suited for clinical environments where pumps are docked and undocked between patient care tasks.
• Drop-In Replacement: Precision-molded to exact OEM dimensions with secure connector fit — no modification required, plugs directly into EA111/EA313/EA3 pump battery compartments.

Safety Protection

• Over-Charge Protection: Terminates charging at 12.6V (4.2V per cell) to prevent cell damage and thermal runaway.
• Over-Discharge Protection: Cuts off output at 9.0V (3.0V per cell) to prevent irreversible capacity loss and ensure pump low-battery alarm triggers correctly.
• Over-Current Protection: Limits discharge current to safe levels, protecting both battery and pump motor during high-torque startup and occlusion events.
• Short-Circuit Protection: Microsecond-level circuit interruption to prevent fire, pump damage, and patient safety incidents.
• Thermal Protection: NTC thermistor continuously monitors cell temperature; suspends charge/discharge if temperature exceeds safe limits.
• Cell Balancing: Active balancing maintains uniform voltage across all 3 cells, maximizing pack capacity and extending service life.

Certifications

• CE Certified — Complies with EU Medical Device Directive safety and performance requirements
• UL Certified — UL 2054 safety standard for lithium battery packs
• RoHS Compliant — Free from lead, mercury, cadmium, and restricted hazardous substances
• UN38.3 Tested — Passes all T1-T8 UN transportation safety tests for lithium batteries
• IEC 62133 Certified — International safety standard for portable sealed secondary lithium cells and batteries
• ISO 9001 — Manufactured in an ISO 9001 certified facility
• UKCA Certified — UK Conformity Assessed marking for Great Britain market compliance

Installation & Maintenance

• Initial Charge: Fully charge the battery (~3-4 hours) before first use to activate all cells and achieve maximum runtime.
• Charging: Use only the XINKE pump charging dock or a compatible 11.1V Li-ion medical device charger. Never use Ni-MH or lead-acid chargers — voltage mismatch will permanently damage the battery.
• Storage: Store in a clean, dry environment at 15-25°C (59-77°F). For long-term storage (>3 months), charge to 40-60% (approximately 11.4-11.7V) and recharge every 3 months. Never store fully discharged.
• Cleaning: Wipe battery housing and contacts with a dry, lint-free cloth. 70% isopropyl alcohol may be used on housing surfaces only — never on electrical contacts.
• Replacement Indicator: Replace when pump displays persistent low-battery warnings shortly after a full charge, or when battery runtime falls below approximately 3.5 hours (70% of original capacity) under standard infusion rates.
• Disposal: Li-ion batteries must be disposed of at certified e-waste recycling facilities. Never incinerate, puncture, or dispose of in general medical waste. Follow hospital biomedical waste disposal SOPs.

FAQ

• Q: Is this an original XINKE battery?
  A: No, this is a high-quality compatible replacement built with Samsung Grade A+ 18650 cells and full safety protection circuitry. It meets or exceeds OEM specifications but is not manufactured by or affiliated with Beijing XINKE Huada Medical Technology Co., Ltd.
• Q: Does this work with all three models — EA111, EA313, and EA3?
  A: Yes. EA111, EA313, and EA3 share the same battery platform and connector. This replacement is a direct drop-in for all three models.
• Q: How long does the battery last on a full charge?
  A: Under typical infusion conditions (single syringe at 10mL/hr), expect approximately 5-7 hours of continuous cordless operation. Actual runtime varies with infusion rate, syringe size, and motor load.
• Q: Can I charge the battery while the pump is running on AC power?
  A: Yes. XINKE syringe pumps support pass-through charging — the battery charges automatically while the pump operates on AC mains power. No need to remove the battery for daily charging.
• Q: Why Samsung cells? Are they better than generic cells?
  A: Samsung Grade A+ 18650 cells offer superior cycle stability, lower internal resistance, and better consistency compared to generic alternatives. This translates to longer service life and more predictable runtime — critical for clinical environments where battery failure can compromise infusion therapy.
• Q: What certifications does this battery carry?
  A: CE, UL, RoHS, UN38.3, IEC 62133, UKCA, and ISO 9001. MSDS documentation is available upon request for hospital procurement compliance.
