Gel battery CSSB LX1245CS 12V 4.5Ah – sealed rechargeable power supply

CSSB LX1245CS is a sealed gel rechargeable battery with a nominal voltage of 12V and a capacity of 4.5Ah. Engineered for both standby and cyclic use, this maintenance-free battery uses gel electrolyte technology to reduce leakage risk and to allow safe installation in various orientations. Its compact form factor and stable output make it suitable for low- to moderate-power applications where reliable backup or portable power is required.

Advantages

The gel construction provides enhanced vibration and shock resistance compared with flooded batteries and minimizes electrolyte movement, reducing the potential for spills. Being sealed and maintenance-free, the battery does not require topping up with water or regular maintenance checks, simplifying installation and ownership. The 12V nominal voltage and 4.5Ah capacity deliver a predictable discharge profile for devices such as alarm panels and small UPS systems, while the sealed design supports mounting in confined or variable-orientation spaces.

Suitable for

• Alarm and security systems
• Uninterruptible power supplies (small UPS)
• Emergency and exit lighting
• Small solar and off-grid devices
• Telecommunications and monitoring equipment

Key specifications

• Nominal voltage: 12 volts
• Capacity: 4.5 ampere-hours (Ah)
• Electrolyte type: gel (sealed)
• Maintenance: sealed, maintenance-free
• Recommended use: standby and cyclic applications
• Mounting: can be installed in various orientations

How to use

Before installation, ensure the device to be powered is compatible with a 12V battery and that its charging circuitry matches sealed gel battery charging profiles. Connect the battery to the equipment following correct polarity and secure terminal connections to prevent intermittent contact. For standby applications, keep the battery charged by the system charger and avoid deep discharges to prolong service life. For cyclic use, follow the recommended charge/discharge cycles and use an appropriate charger that supports gel-type batteries to maintain capacity and longevity.

Usage recommendations

Store and operate the battery within manufacturer-recommended temperature ranges; avoid prolonged exposure to high temperatures. Regularly check system charge voltage and replace the battery when capacity drops significantly to ensure reliable backup performance.
