Gel battery BLOW 12V 28Ah for UPS, standby power and backup

Sealed gel battery BLOW 12V 28Ah is a maintenance-free, valve-regulated lead-acid battery designed for UPS units, standby power supplies and backup installations. The gel electrolyte and robust construction provide a stable 12V output and a rated capacity of 28Ah, delivering reliable power for short- to medium-duration outages. The battery is suitable for indoor installations where a spill-proof, vibration-resistant power source is required.

Advantages

The gel design prevents electrolyte leakage and reduces the need for servicing, while the valve-regulated construction minimizes gas emissions and eliminates the need to add water. Its sealed casing and vibration resistance increase operational safety and longevity in enclosed equipment compartments. Consistent 12V output and a 28Ah capacity ensure predictable runtime with compatible UPS and standby systems.

Suitable for

• Uninterruptible Power Supplies (UPS) for home or small office systems
• Standby power for emergency lighting and alarm systems
• Telecommunications and network equipment backup
• Small-scale renewable energy systems and charge controllers
• Portable power modules and testing equipment

How to use

Install the battery in a compatible UPS or enclosure following the equipment manufacturer’s instructions. Ensure correct polarity when connecting; observe the recommended charge parameters of the host device or charger for gel lead-acid batteries. Place the battery in a well-ventilated, temperature-stable area away from direct heat sources. Regularly check the host system’s indicators and perform periodic capacity tests according to the UPS or system maintenance schedule.

Usage recommendations

For longest service life, store and operate the battery at moderate ambient temperatures and keep it charged when not in use. Use a charger or UPS with gel/AGM-compatible charging profiles and avoid deep discharges where possible. Dispose of the battery in accordance with local regulations for lead-acid batteries.
