SWL Valve Regulated Lead-Acid Batteries (VRLA)

The SWLrange is an enhanced NPLdesign 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.

FEATURES• 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.

CAUTION- 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.

WARNING!SWL (Standard) and (FR) battery types SWL1850;SWL1850-6; SWL2500, must never be installed per-manently suspended by their handles; they are notdesigned for this purpose.
