Sealed AGM battery Volt Polska VPRO 12V 40Ah — rechargeable lead‑acid battery for UPS and standby use

Volt Polska VPRO 12V 40Ah is a sealed AGM rechargeable lead‑acid battery intended for UPS, standby and backup power applications. The battery delivers a nominal 12 V and 40 Ah capacity in a maintenance‑free, spill‑proof housing that uses absorbed glass mat (AGM) technology. Its sealed construction reduces the need for regular service and allows horizontal or vertical installation in confined equipment racks, telecom cabinets and emergency power modules.

Advantages

The sealed AGM design provides low self‑discharge, good cyclic and float performance and minimal gas emission under normal charging conditions, making it suitable for long‑term standby use. With a compact rectangular case and standardized terminal arrangement, the battery supports straightforward replacement of common UPS and alarm system batteries. Maintenance‑free operation and spill‑proof construction improve safety during handling and reduce installation requirements in confined or indoor environments.
