The 12 V 250 Ah GEL battery is a sealed, maintenance-free deep-cycle battery designed for reliable, long-lasting performance in a variety of applications: solar energy systems, backup power supplies, telecommunications, emergency lighting, and more. Its gel-electrolyte design ensures safety (no spills or leaks), stable power delivery over long discharge cycles, and durability even under harsh conditions. It is ideal for users who require dependable DC power with minimal maintenance and high resilience across different environments.

KEY BENEFITS

• GEL technology with immobilized electrolyte — ensures zero leakage, safe operation even if the battery is tilted or exposed to vibrations.
• Deep-cycle design — suitable for repeated charge/discharge cycles (e.g. solar systems, UPS, backup), with good recovery after deep discharges.
• High capacity (250 Ah at 12 V) — delivers ample energy storage, making it suitable for medium to high power demands over extended periods.
• Low self-discharge and long shelf-life — retains charge effectively when idle, reducing maintenance and ensuring readiness when needed.
• Wide operating temperature range — can function reliably in varied conditions, useful for solar installations, backup systems, and outdoor use.
• Maintenance-free and sealed construction — no need to add water or check acid levels, simplifying usage and increasing safety.
• Versatile applications — from solar energy storage to telecommunications, emergency systems, electric vehicles or marine applications.
