UNIKOR VT Sealed Lead-Calcium Rechargeable Battery is leak-proof and maintenance free. The superiority of NUIKOR VT battery is derived from its uniquely efficient oxygen recombunation technology.

The oxygen evolved from the positive plates diffuses through the microporous glass fibers to the negative plates where it is changed back to water by recombination reaction and, it makes no need of additional water filling.
The result is a maintenance free battery.

• Sealed Construction
  Unikor's unique construction and sealing technique ensures that no electrolyte leakage can occur from the terminals or cases of any VT batteries. This feature ensure safe and efficient operation of VT batteries in any position.
• Absorptive Mat system
  VT batteries make use of fine mat separators(glass fiber) wherein sufficient electrolyte is absorbed to provide longer life and steady service. This system prevents escape of electrolyte from the separator which causes leakage.
• Gas Generation
  VT batteries incorporate a unique design the effectively controls gas generation and allows recombination of inside the battery over 99% of gas generated during the normal use.
• Maintenance-Free Operation
  During the expected floating service life of VT batteries there is no need to check the specific gravity of the electrolyte, or water addition, which means thery require no maintenance service.
• Position-Free and Leakage-Free
  The combination of the sealed construction and the use of absorptive mat separators permits operation of VT batteries in any position without loss of capacity, electrolyte, nor service life. The VT batteries are made to operate in any position
• Pressure Venting System
  VT batteries are equipped with a safe, and low pressure venting system, which operates at 7 psi to 10psi, automatically releasing excess gas in the event that gas pressure rises to a level above the normal rate ensuring no excessive buildup of gas in the batteries.
  Resealing is automatic once the pressure is returned to normal.
• Heavy-Duty Grids
  The VT heavy-duty Lead Calcuim-alloy grids provide an extra performance and service life in both cyclic and floating applications even in deep discharge condition.
• Cyclic Life
  Depending on the average depth of discharge, over 1,000 discharge/recharge cycle can be expected from VT batteries.
• Float Life
  The expected life of VT 6V, 12V batteries using under float(trickle charge) use is 4 to 8 years.
• Low Self-discharge, Long Shelf Life
  At an ambient temperature of 5°C(77°F), the self-discharge rate VT batteries is only3%(approx.) of rated capacity per month. The low self-discharge rate permits storage of VT batteries for up to one year without significant losses of efficiency or appreciable deteriration of performance.
• Operating Temperature Range
  VT batteries may be used over a broad range of ambient temperatures permitting flexible system design and location.
  -Charge : -10~40°C(14~104°F)
  -Discharge : -20~50°C(-4~122°F)
  -Storage : -20~40°C(-4~104°F)
• HIgh Recovery Capability
  VT batteries have an excellent charge acceptance and recovery capability even after deep discharging
