NPL Valve Regulated Lead-acid Battery (VRLA)
The NPL range is an enhanced NP design resulting in a longer service life (7 - 10yrs).
All other attributes and operational characteristics are the same, thereby maintaining the benefit of a common mechanical and electrical design for users of both products.
FEATURES
• Yuasa VRLA batteries can be used in any orientation excluding continuous use inverted.
• Standard case material is flame retardant to (UL94) HBØ.
• NPL batteries are manufactured in factories that comply with ISO 9001:2000.
• NPL batteries comply with IEC 60896-21+22.
Applications
• Security and Fire
• UPS
• Telecoms
• Emergency Lighting
