Long-Life Maintenance-Free Lead-Acid Storage Battery — Telecom & Backup Power Solution

• 8-12 year design life — thick high-density plates and advanced alloy composition for extended service
• AGM (Absorbent Glass Mat) technology — electrolyte immobilized in glass fiber, spill-proof and leak-proof
• Low self-discharge rate (< 3%/month) — ideal for standby and seasonal applications
• Wide operating temperature range — reliable performance from -20℃ to 50℃
• Flame-retardant ABS container (UL94-V0) — meets strict safety requirements for indoor telecom installations
• Copper insert terminals — low resistance, corrosion-resistant connections for reliable power delivery
• GEL option available — superior deep-cycle performance and longer cycle life for frequent discharge applications

• Telecommunications — Primary backup power for cell towers, base stations, and fiber optic nodes
• UPS Systems — Battery banks for data centers, hospitals, and industrial uninterruptible power supplies
• Solar Energy Storage — Cost-effective storage for off-grid and hybrid solar power systems

Q: What's the difference between AGM and GEL batteries?

A: AGM offers higher discharge rates and is better for UPS/high-current applications. GEL provides deeper cycle capability (800+ cycles) and better performance in high-temperature environments.

Q: Do these batteries require ventilation?

A: VRLA batteries emit minimal hydrogen under normal charging. For large battery banks in enclosed spaces, natural ventilation is sufficient. For rooms with > 10 batteries, mechanical ventilation is recommended.

Q: How should I dispose of old batteries?

A: Lead-acid batteries are 99% recyclable. Return spent batteries to authorized recycling centers. JYINS supports take-back programs for bulk customers.

Q: Can these be used in series for 24V/48V systems?

A: Yes, connect 2 batteries in series for 24V, or 4 for 48V. Ensure all batteries in a series string are the same model, capacity, and age for balanced charging.
