Product information

Description

The COSI CSB-1240 GEL is a 12V 40Ah sealed gel lead‑acid battery designed to provide reliable standby and cyclic power in a compact maintenance‑free package. Its gel electrolyte construction minimises the risk of leakage and allows installation in a variety of orientations. The battery is intended for systems that require stable 12V DC power with moderate capacity and predictable discharge and recharge characteristics.

Advantages

The gel electrolyte and sealed construction eliminate the need for regular water topping and reduce the risk of spillage, making the battery suitable for indoor and enclosed installations. The battery delivers stable voltage under load and offers good deep‑discharge recovery compared to standard flooded lead‑acid types. Its maintenance‑free design and robust casing support safe, long‑term standby operation and repeated cyclic use in appropriate systems.

Suitable for

  • Uninterruptible Power Supplies (UPS) for small to medium systems
  • Alarm and security systems
  • Telecommunications equipment and network devices
  • Solar backup and off‑grid 12V systems with moderate energy needs
  • Emergency lighting and medical standby devices

Key specifications

  • Nominal voltage: 12 volts
  • Nominal capacity: 40 ampere‑hours (Ah)
  • Battery type: sealed gel lead‑acid
  • Design: maintenance‑free, valve‑regulated
  • Installation: can be mounted in multiple orientations due to gel electrolyte
  • Typical applications: standby and cyclic use with moderate depth of discharge

How to use

Install the battery in a well‑ventilated area away from direct heat sources and corrosive environments. Connect using appropriate battery leads and terminals compatible with the device’s polarity and current rating. For standby applications, keep the battery on a suitable float/standby charger to maintain full charge and prevent sulfation. For cyclic use, follow the recommended charge algorithm for gel lead‑acid batteries: controlled constant current charge followed by a lower constant voltage phase until current tapers to a small value.

Usage recommendations

Store and operate the battery at moderate ambient temperatures for optimum lifespan. Regularly check connections for corrosion and ensure the charging equipment is set for gel battery parameters (lower charge voltages than flooded types). Replace the battery when capacity drops below the level required for reliable operation of your equipment.
