This is a genuine Yuasa NPX-L35FR rechargeable sealed lead-acid (SLA) battery. Yuasa’s NPX industrial batteries are designed for high-rate discharge applications, and are considered to be among the best SLA batteries on the market.

  • Sealed, leak proof construction.
  • Float service life: estimated 5 years.
  • Service life: 1,000+ charge/discharge cycles.
  • Fire retardant (FR) casing.
  • Excellent performance in either float or cyclic applications.
  • Usable in any orientation.
  • UL listed.

Features and Benefits for the Yuasa NPX-L35FR from the Yuasa NPX-35L Spec Sheet:

  • Designed for high rate discharge applications – used primarily where high wattage is required for a short duration.
  • No gels or other contaminants are added.
  • Superior Value – NPX batteries feature 50% more wattage available and a 30% reduction in size over conventional batteries.
  • Sealed Construction – unique construction and sealing ensures no electrolyte leakage from case or terminals.
  • Electrolyte Suspension System – incorporates a microfine glass mat to retain the maximum amount of electrolyte in the cells.
  • Control of Gas Generation – The very latest oxygen recombination technology effectively controls the generation of gas during normal use.
  • Low Maintenance Operation – Battery is nearly maintenance free due to the perfectly sealed construction and the recombination of gasses within the cell.
  • Operation in any Orientation– Sealed construction and electrolyte suspension system allows usability in any orientation (with no loss of performance or electrolyte leakage).
  • Valve Regulated Design – Equipped with a low pressure venting system that automatically releases excess gas and reseals.
  • Lead Calcium Grids – Provides an extra margin of performance and life (in both cyclic and float applications).
  • Long Cycle Service Life – Over 1000 discharge/charge cycles can be expected depending upon the average depth of discharge.
  • Float Service Life – Expected service life is 5 years in float standby applications.
  • Separators – Special separator material provides efficient insulation between plates. This prevents inter-plate short circuits and the shedding of active materials.
  • Long Shelf Life – Low self discharge rate allows the battery to be stored for extended periods (up to 1 year at normal ambient temperatures) with no permanent loss of capacity.
  • Operating Temperature Range:
    • Charge – 15°C to 50°C
    • Discharge – 20°C to 60°C
    • Storage – 20°C to 50°C (fully charged battery)
