Sealed Lead Acid Battery Green Cell AGM51 12 V 17 Ah, VRLA, maintenance-free, 167×77×181 mm, 4.8 kg

The Green Cell AGM51 17 Ah 12 V is a sealed lead acid (VRLA) battery engineered for stable, maintenance-free power in equipment that requires a compact 12 V supply. With a capacity of 17 Ah and a compact form factor, this battery provides a balance of stored energy and footprint suitable for standby and cyclic applications. The unit is supplied in a sturdy black housing and is intended for use where a sealed, spill-proof battery is required.

Advantages

The AGM51 uses absorbed glass mat (AGM) technology within the VRLA design to reduce internal resistance and improve charge acceptance. Its sealed construction eliminates the need for electrolyte maintenance and allows for installation in multiple orientations. The battery’s moderate weight and small dimensions make it convenient to install in confined spaces, while the construction offers reliable performance across typical operating conditions for lead acid batteries.

Suitable for

• Uninterruptible Power Supplies (UPS) for home or small office equipment
• Emergency lighting systems and exit signs
• Alarm and security systems
• Low-power mobility devices and portable equipment
• Backup power for telecommunications and network devices

How to use

Install the battery in a dry, well-ventilated enclosure designed for lead acid batteries, ensuring secure mechanical fixation and correct polarity connections. Use compatible chargers and charge controllers specified for 12 V VRLA/AGM batteries and follow recommended charge voltages and temperature compensation where applicable. For standby applications, maintain a float charge according to equipment manufacturer guidance; for cyclic use, follow the charger’s cyclic charging profile. Avoid deep discharges below the recommended depth of discharge to prolong service life.

Recommendations

Store and install the battery at moderate temperatures, avoiding prolonged exposure to high heat or freezing conditions. Periodically inspect terminals for secure connections and clean corrosion if present. Replace batteries that show persistent capacity loss or visible damage. Dispose of the battery according to local regulations for lead-acid battery recycling.
