Key Features

• Grade A+ Li-ion Cells: High-quality 18650 cells deliver stable 14.4V output with consistent capacity, ensuring reliable NPWT pump operation throughout the entire wound therapy session.
• Lightweight & Portable Design: At just 185g, this compact battery maintains the RENASYS GO's portability advantage — patients can remain mobile during post-acute wound care without being tethered to AC power.
• Extended Therapy Runtime: 2600mAh / 37.44Wh capacity provides sufficient power for typical NPWT treatment cycles, allowing uninterrupted negative pressure delivery during patient ambulation and transport.
• No Memory Effect: Li-ion chemistry supports partial discharge and frequent top-up charging without capacity degradation — ideal for clinical settings where the device is charged between patient use.
• Drop-In Replacement: Precision-molded to exact OEM dimensions (65.4 x 34.5 x 47.5mm), ensuring seamless fit in the RENASYS GO battery compartment with secure electrical contact.

Safety Protection

• Over-Charge Protection: Terminates charging at 16.8V (4.2V per cell) to prevent cell over-voltage and thermal runaway.
• Over-Discharge Protection: Cuts off output at 12.0V (3.0V per cell) to prevent irreversible capacity loss.
• Over-Current Protection: Limits discharge current to protect both battery and RENASYS GO pump motor during peak draw.
• Short-Circuit Protection: Instantaneous circuit cutoff to prevent fire, equipment damage, and patient safety risk.
• Thermal Protection: Built-in NTC thermistor monitors cell temperature; suspends operation if overheating detected during charging or extended therapy use.
• Cell Balancing: Active balancing circuit maintains uniform voltage across all 4 cells, maximizing pack capacity and service lifespan.

About Smith & Nephew RENASYS GO

The RENASYS GO is a portable Negative Pressure Wound Therapy (NPWT) system manufactured by Smith & Nephew, a global leader in advanced wound management. Designed for post-acute care settings, this sleek, lightweight device applies controlled negative pressure to a closed wound environment, continuously evacuating exudates into a disposable canister while promoting granulation tissue formation and wound closure. The RENASYS GO is widely used across home healthcare, skilled nursing facilities, outpatient wound clinics, and hospital post-discharge programs. Its compact size and quiet operation allow patients to maintain mobility and dignity during treatment — the built-in rechargeable LG144 battery is essential to this portability, powering the pump during daily activities, sleep, and transport without tethering patients to wall outlets. A reliable replacement battery is critical for uninterrupted NPWT delivery and optimal wound healing outcomes.

Installation & Maintenance

• Initial Charge: Fully charge the battery (approximately 2-3 hours) before first use. The RENASYS GO charging indicator will signal when complete.
• Charging: Use only the Smith & Nephew-provided RENASYS GO charging dock or compatible 14.4V Li-ion medical device charger. Do not use third-party universal chargers without verifying voltage and polarity.
• Storage: Store in a cool, dry environment (15-25°C / 59-77°F). For extended storage (over 3 months), charge to 40-60% capacity (approximately 15.0-15.4V) and recharge every 3 months to prevent deep discharge.
• Cleaning: Wipe battery housing with a damp cloth using mild detergent if needed. Ensure contacts are dry and free of debris before insertion. Never immerse in liquid or use abrasive cleaners.
• Replacement Indicator: Replace when battery runtime drops noticeably (consistent early low-battery alerts) or the RENASYS GO fails to complete a full NPWT cycle on a single charge.
• Disposal: Li-ion batteries must be disposed of at certified e-waste recycling facilities per local regulations. Never incinerate, puncture, or dispose of in general waste.

FAQ

• Q: Is this an original Smith & Nephew battery?
  A: No, this is a high-quality compatible replacement built with Grade A+ 18650 Li-ion cells and full safety protection circuitry. It is not manufactured by or affiliated with Smith & Nephew.
• Q: Will this fit my RENASYS GO device?
  A: Yes. This battery is precision-molded to exact OEM dimensions and is compatible with all RENASYS GO NPWT devices. It replaces part numbers LG144, 510001-144, and Smith & Nephew No.2001584.
• Q: How long does the battery last on a full charge?
  A: Runtime depends on the NPWT pressure setting and exudate level. Under typical therapy settings (-125mmHg continuous), expect approximately 8-12 hours of operation. Higher pressure or intermittent mode may reduce runtime.
• Q: Can I use the RENASYS GO while charging?
  A: The RENASYS GO is designed for cordless operation during therapy. The battery should be charged using the dedicated charging dock. Always have a spare fully charged battery available for uninterrupted therapy during extended use.
• Q: How does NPWT battery failure affect patient care?
  A: NPWT interruption can lead to exudate pooling, increased infection risk, and delayed wound healing. Having a reliable replacement battery is essential for ensuring continuous negative pressure delivery and optimal clinical outcomes.
• Q: What certifications does this battery carry?
  A: CE, RoHS, UN38.3, and MSDS documentation are available upon request.
