Batteria al piombo-acido sigillata (VRLA) 12V 9Ah Extralink – AGM, 1 pezzo, nero

The Extralink Sealed Lead Acid (VRLA) Battery 12V 9Ah is a maintenance‑free, rechargeable battery designed for backup power applications. Constructed using AGM (Absorbent Glass Mat) technology, this single black unit provides stable 12 V output and a 9 Ah capacity suitable for UPS systems, alarm panels, emergency lighting and other small to medium standby loads. As a VRLA battery, it is spill‑proof and does not emit gases under normal conditions, allowing flexible installation and reducing the risk of electrolyte leakage and corrosion.

Advantages

AGM construction ensures a sealed, valve‑regulated design that delivers reliable voltage stability and low internal resistance. The battery requires no maintenance, is spill‑proof and can be mounted in various orientations. Its compact form factor and consistent charge/discharge characteristics make it suitable for repeated cycling in standby and occasional use scenarios. The sealed design also reduces environmental contamination and eliminates the need for special ventilated locations during normal operation.

How to use

Install the battery in a compatible holder or compartment following the equipment manufacturer’s polarity markings and connection instructions. Use a charger or charging circuit designed for 12 V SLA/VRLA batteries to avoid overcharging; follow recommended constant voltage charging parameters for AGM batteries. Ensure connections are secure and check voltages after initial charging. For UPS and alarm installations, connect the battery to the designated battery terminals and verify the system performs switchover and battery charging functions as specified by the system manual.

Recommendations

Store and operate the battery at moderate ambient temperatures for best life; avoid prolonged exposure to extreme heat or freezing conditions. Periodically inspect terminals for secure connections and clean any corrosion. Replace the battery when capacity falls below the level required by your backup application or when the device indicates end‑of‑use life. Dispose of used batteries according to local regulations for lead acid batteries.
