The Fullriver HGXL200-2 is a 2-volt, 200 Ah (10-hour rate) stationary AGM cell from Fullriver’s long-life HGXL series. It is a single-cell design: you build exactly the bank you need \u2014 12, 24 or 48 V, or a higher string for telecom and UPS \u2014 from identical cells, and if a cell ever needs attention you test or replace that one cell rather than a whole battery. The grids are cast in a lead-calcium-tin alloy for corrosion resistance, which is what gives the series its 20-year design life in float service. Sealed, valve-regulated and maintenance-free, with no free acid to top up or spill, so cells can be racked in any orientation.<\/p>\n
The core of the range for off-grid and hybrid solar storage on houses, resorts and island properties, marina and yacht-club shore installations, and standby power for pumps, gates, communications and security systems. Sized on the 10-hour rate, a bank of these cycles gently every night and is built to keep doing so for years.<\/p>\n
Long-life solar and standby banks are built from 2 V cells for good reasons. Capacity per cell runs far beyond anything a 12 V case can hold, so a big bank is one clean string instead of a web of parallel blocks. Every cell can be measured, equalised and replaced on its own. And HGXL cells are rated at the 10-hour rate \u2014 the honest rate for solar and standby duty \u2014 with the 1-, 3- and 5-hour figures published too, so you can size for heavier loads without guesswork.<\/p>\n
