Product information

Description

Sealed Gel 12V rechargeable battery COSI CSB-1228 GEL provides a stable 12 V output with a nominal capacity of 28 Ah in a valve-regulated lead-acid (VRLA) gel format. The sealed gel electrolyte and maintenance-free design make this battery suitable for indoor installations where leak resistance and vibration tolerance are required. It is designed for standby power, cyclic use within manufacturer conditions, and applications where a reliable, compact 12 V energy source is needed.

Advantages

The gel electrolyte and VRLA construction deliver leak-proof performance and reduced risk of acid spills, enabling safe indoor use and varied mounting orientations. The maintenance-free design eliminates the need for periodic water topping. The battery offers stable output under standby conditions and predictable cyclic behaviour when used according to recommended charge and discharge parameters. Its vibration resistance and sealed case enhance longevity in environments with mechanical stress.

Suitable for

  • Uninterruptible power supply (UPS) systems for short-term backup
  • Alarm and security panels
  • Small off-grid or auxiliary solar systems
  • Mobility devices and medical equipment with appropriate specifications
  • Telecom standby modules and monitoring equipment

Key specifications

  • Nominal voltage: 12 V
  • Nominal capacity: 28 Ah
  • Electrolyte type: Gel (VRLA)
  • Design: Sealed, maintenance-free
  • Mounting: Suitable for horizontal or specified alternative orientations
  • Performance: Designed for standby and cyclic operation within recommended parameters
  • Operating environment: Indoor use; avoid prolonged exposure to extreme temperatures

How to use

Install the 12 V gel battery in a well-ventilated, dry indoor location on a flat, stable surface and secure it according to the equipment manufacturer’s instructions. Connect to the system using correct polarity and suitable terminal connections; ensure charging equipment is compatible with gel-type VRLA chemistry and configured for the battery’s nominal voltage and capacity. Avoid deep discharges and follow the recommended charge voltage and current limits from your system documentation to maximize service life. For cyclic use, follow charge/discharge profiles appropriate for gel batteries.

Usage recommendations

Store and operate the battery within the manufacturer’s recommended temperature range to preserve capacity and service life. Use a charger with gel/VRLA settings or an adjustable charger set to the appropriate float and cycle voltages for gel batteries. Periodically inspect terminals for secure connections and clean any corrosion with appropriate precautions. Replace the battery when capacity falls below acceptable levels for your application.
