YUASA Lead-Acid Rechargeable Batteries
Rated Voltage: 6V
Series: NP

Application
Uninterruptible power supplies (UPS), emergency lighting, photovoltaic applications, testing equipment and measuring devices.
Features
• Service-free operation
• Very good charging efficiency
• Expected Design Life: 3 to 5 years
• Good cycle durability according to discharge intensity, more than 1000 discharging/recharging cycles
• Extended shelf life at low self-discharge level
• Valve regulated design
• Absorbing GlassMatt technology in which the electrolyte is fully absorbed (AGM = Absorbing GlassMatt Technology)
• Mechanically strong ABS container, extremely flame-retardant according to UL94HB
• NP batteries can be operated permanently when lying on the side; any operation upside down is solely permissible for one discharge
• Corrosion reduction using a lead-tin-calcium alloy to extend service life
• Excellent high current performance

Charging Methods
The valve-regulated Yuasa batteries should only be charged at a constant voltage with a current limitation of 0,1CA to max. 0,25CA.
Trickle Charge
Constant charging voltage of 2,275V/cell at 20°C.
Cycle Use
Constant charging voltage at 2,45 ... 2,5V/cell at 20°C, charging time 20h max.

Service Life Expectancy
The expected operating service life of the NP series is 3 to 5 years. This can be achieved under optimal operating conditions if a permanent battery temperature of 20°C is maintained. The battery with a float charge voltage of 2,275V/cell is charged and one of the local constant charging currents does not cross the effective ripple current value of 0,1CA.
