Description

A high-quality, maintenance-free battery manufactured using modern AGM (Absorbent Glass Mat) technology, it is a reliable energy source designed for the most demanding backup power systems. The device belongs to the MWP series, which is characterized by a significantly extended design life of over 12 years. This makes it an ideal choice for installations where long-term stability and infrequent cell replacement are critical.

The main advantage of AGM technology is the complete absorption of the electrolyte in glass fiber mats, which eliminates the risk of leakage and allows the battery to operate in almost any position. It is a fully safe and maintenance-free solution that does not require topping up water. The battery exhibits very low internal resistance, which translates to higher terminal voltage and longer runtimes, especially during high-current discharges.

The product has a wide range of applications - from alarm systems (SSWiN) and fire protection systems (PPOZ), through buffer power supplies and UPS systems, to emergency lighting installations and industrial automation systems. The sturdy housing made of durable plastic provides resistance to mechanical damage, and the M5 screw terminals guarantee a secure electrical contact and ease of installation. By choosing this model, you are investing in a premium product that provides peace of mind and continuity of power for many years of operation.
