Protect critical load continuity with a replacement battery kit designed for Vertiv Liebert GXT4 high-capacity UPS systems. The GXT4-288VBATKIT delivers 288 V of lead-acid battery power in a hot-swappable internal format, so maintenance can be performed without shutting down the UPS or interrupting protected infrastructure. Built for the GXT4-8000RT208 and GXT4-10000RT208, this battery kit restores the runtime profile expected from enterprise UPS deployments where downtime is not acceptable. Its 9 Ah capacity and spill-proof construction support dependable operation in rack-based environments that demand predictable backup power and controlled serviceability. For infrastructure teams, the value is straightforward: replace aging batteries before they become a risk, preserve UPS readiness, and avoid the cost of unplanned outages. A 2-year limited warranty adds another layer of confidence for environments where battery health directly affects service continuity. When the UPS is protecting storage, network, or compute loads, the right replacement battery is not a commodity part — it is part of the uptime strategy.
