Cosel UPS batteries utilize an automatic safety valve (VRLA) to prevent gas inhalation into the battery, affecting its performance, and also to avoid damage to the battery due to abnormal internal pressure caused by gases produced during charging, etc. The fully enclosed batteries do not emit electrolyte or acid mist under normal float charging. Additionally, the batteries are paired with battery trays using proprietary patented technology, ensuring safer use of the battery assembly.

Key Product Features

No maintenance required

Utilizing the exclusive gas recombination technology (GAS RECOMBINATION). No need for regular liquid topping up and maintenance, alleviating user concerns post-purchase.

High safety and reliability

Utilizing an automatically operable safety valve (VRLA) prevents gas from being吸入 into the battery, affecting its performance, and also safeguards against internal pressure damage caused by gases produced during charging. Furthermore, under normal float charging, there is no electrolyte or acid mist discharge. Additionally, the battery tray, using our proprietary technology, is designed for use with the batteries to ensure safer battery assembly operation.

Long service life

At 20°C, the float life of FM series small sealed batteries is up to 3-5 years, the float life of FM fixed sealed batteries is up to 8-10 years, the float life of FML series batteries is up to 10 years, the float life of FMH series batteries is up to 10 years, the float life of GFM series and solar deep cycle series batteries is up to 15 years, and the float life of GFMJ series batteries is up to 18 years.

Low self-discharge rate

Utilizing lead calcium alloy, the self-discharge rate of the battery is reduced. Under an ambient temperature of 20°C, Cosda's batteries can be used normally without needing to recharge for 6 months.

High conductivity

Utilizing silver-plated copper core terminals and special design ensures electrical performance.

Strong directional characteristics

Special separator (AGM) securely absorbs the electrolyte, preventing it from flowing. The battery will not leak whether it is standing or lying down, ensuring normal operation.

Highly adaptable to environments; pollution-free

Operable in ambient temperatures ranging from -20°C to +50°C, suitable for desert and alpine climates. Can be used with special power supplies for explosion-proof areas.

Battery rooms do not require acid-resistant and corrosion-preventive measures and can be housed in the same room as electronic instruments and equipment.
