Lead-acid Rechargeable Battery GRAPHITE 12V 18Ah (model 12V/18AH-SBL/SSB)

GRAPHITE 12V 18Ah lead-acid rechargeable battery (model 12V/18AH-SBL/SSB) is a sealed 12‑volt energy source with an 18 ampere‑hour capacity. It is designed for compact, maintenance‑free operation in standby and cyclic applications, providing reliable backup power for security systems, uninterruptible power supplies (UPS), emergency lighting and small energy storage installations. The battery's sealed construction minimizes electrolyte leakage and allows flexible installation orientation.

Advantages

The sealed lead‑acid chemistry delivers stable voltage output and predictable discharge characteristics suitable for both standby and cyclic use. Its 18 Ah capacity balances compact size with enough energy to support low‑to‑medium load devices for extended periods. The maintenance‑free design reduces the need for servicing, while the robust construction makes it suitable for installation in cabinets or small enclosures. Designed for general compatibility, the battery integrates with common 12 V systems used in security, lighting and backup applications.

Suitable for

• Backup power for alarm and security systems
• Uninterruptible power supplies (UPS) for small equipment
• Emergency and exit lighting
• Small off‑grid energy storage and photovoltaic charge buffering
• Portable 12 V devices and testing equipment

Key specifications

• Nominal voltage: 12 V
• Capacity: 18 Ah (ampere‑hours)
• Sealed lead‑acid construction (maintenance‑free)
• Designed for standby and cyclic applications
• Compact form factor for cabinet and enclosure installation

How to use

Install the battery in a dry, well‑ventilated location away from direct heat sources. Connect positive and negative terminals to the corresponding system leads, ensuring correct polarity and firm terminal connections. For standby applications, maintain the battery on a compatible float charger or charger built into the host device to prevent deep discharge. For cyclic use, follow the system's charging profile and avoid prolonged deep discharges to preserve capacity and service life.

Usage recommendations

Store and operate the battery within recommended temperature ranges for lead‑acid batteries, avoid freezing conditions, and ensure periodic charging if the battery is not in continuous use. Verify compatibility with the charging equipment and protection circuitry of the host system before installation. Dispose of the battery according to local regulations for lead‑acid batteries.
