Sony VJS111D11N Battery – Engineered for Peak Performance

Designed exclusively for Sony devices, the VJS111D11N battery leverages advanced lithium-ion cell technology to deliver extended runtime. Built to strict OEM specifications and certified with CE/UL/ROHS/ISO9001/9002 standards, it ensures safety and reliability. The precision-engineered interface with premium insulation materials guarantees stable power transfer and maximizes battery lifespan.

Premium Cell Technology
- A-grade lithium-ion cells undergo 100% grading and screening, offering 20% higher capacity retention compared to standard batteries.
- VJS111D11N battery extended cycle life of over 500 cycles (80% capacity retention), providing 1.5x longer service life than conventional options.
Aerospace-Grade Manufacturing
- Electrical Excellence:
  - Resistance welding reduces internal resistance to <15mΩ, while 3μm gold-plated contacts minimize impedance loss.
  - Intelligent BMS (Battery Management System) with <50ms response time provides over-voltage, over-current, and over-temperature protection.
- Structural Integrity:
  - MIL-STD-810G-certified composite housing (ABS+PC) withstands 1.2m drop impacts.
  - V0-rated flame-retardant materials meet UL94 fire safety standards.
  - IP67 water resistance safeguards against accidental spills.
Extreme Environment Validation
- Environmental Testing:
  - 5,000m altitude simulation
  - -40°C to 85°C temperature cycling (1,000 cycles with no performance degradation)
  - 96-hour salt spray corrosion test
- Mechanical Durability:
  - 3,000-cycle plug/unplug testing (contact wear <0.05mm)
  - 10Hz-500Hz full-spectrum vibration testing with zero structural damage
Smart Features
- Adaptive charging algorithm supports fast charging (device-dependent).
- software-integrated VJS111D11N battery calibration ensures accurate fuel gauge readings.
- Real-time monitoring system tracks temperature, voltage, and current with <0.5% error margin.

This Sony VJS111D11N battery has passed Sony’s global lab’s 1,200+ rigorous tests, including full lifecycle simulations of Sony laptops/workstations. For optimal performance, pair with Sony original chargers.
