Deep Cycle UPS Battery 2v400ah Sealed Lead Acid For Off Line /
Online UPS Power
1 Equalization charges are not required, reducing maintenance and
2 Our newly developed lead-calcium-tin alloy greatly reduces grid
corrosion resulting in extended life (15-20 year life expectancy in
float service at 20-25°C ambient temperature).
3 Large-sized VRLA Battery Series battery is manufactured in
accordance with JIS C 8707
4 Adding water or taking specific gravity measurements are not
required. There is also no need for an equalization charge.
5 The container and cover are made of flame retardant plastics
which meet UL-94V-0 specifications.
