1. Standard Universal Size for Direct UPS Replacement

   The standard 1516594mm shell size matches most mainstream 12V5Ah UPS battery compartments globally. Plug-and-play replacement without modifying the UPS cabinet structure, greatly reducing after-sales installation difficulty.

2. Fully Sealed Leak-Proof & Zero Maintenance

   Hermetic safety valve sealing technology locks electrolyte inside the battery housing, completely avoiding acid leakage. No regular water refilling required, safe to install inside closed UPS equipment without corrosion risk to circuits.

3. Reliable Stable Backup Performance for Power Outages

   Optimized lead-calcium alloy plate design realizes ultra-low self-discharge rate. It maintains steady voltage output during long-time floating standby, provides sufficient power reserve to protect computers, routers and monitoring devices from sudden power failure.

4. Complete Global Export Compliance Certifications

   All GS series batteries pass CE marking and REACH hazardous substance testing, fully meet import standards of Europe, North America, Southeast Asia and other regions, supporting smooth customs clearance for bulk overseas orders.

5. Long Service Life & Wide Temperature Adaptability
