SWL1850 Data Sheet - AETES

1 SWL Valve regulated Lead- acid Batteries ( vrla )The SWLrange is an enhanced NPLdesign resultingin an improved energy to density ratio, giving up to40% extra discharge capacity. All other attributes andoperational characteristics are the same, therebymaintaining the benefit of a common mechanical andelectrical design for users of both Yuasa vrla batteries can be used in any orientationexcluding continuous use inverted. Standard case material is flame retardant to (UL94) HB . FR option case material is flame retardant to UL94:V (oxygen index 30). SWL batteries are manufactured in factories that complywith ISO9001:2000. FR option SWL s comply with BS6290 Part 4 (1997).
