Valve Regulated Lead-Acid Batteries
SWL series valve regulated lead acid batteries are an enhanced NPL design resulting in an improved energy to density ratio, giving up to 40% extra discharge capacity. 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. SWL Series are the ideal choice of battery for uninterruptible power supply (UPS) and high rate discharge applications.
Yuasa VRLA batteries can be used in any orientation excluding continuous use inverted.
Standard case material is flame retardant to (UL94) HBØ.
FR option case material is flame retardant to UL94:VØ (oxygen index 30).
SWL batteries are manufactured in factories that comply with ISO9001:2000.
FR option SWL’s comply with BS6290 Part 4 (1997).
SWL batteries comply with IEC 60896-21+22.
Applications for SWL Series valve regulated lead acid batteries
Uninterruptible power supply (UPS)
High rate discharge applications.
Charging Methods (At 20°C)
Standby use: Float charging voltage 2.275vpc
Avoid short circuit.
Do not charge in a sealed container.
Service life and operational characteristics will be affected by temperature.
AC Ripple reduces service life.
SWL (Standard) and (FR) battery types SWL1850; SWL1850-6; SWL2500, must never be installed permanently suspended by their handles; they are not designed for this purpose.
