Sealed VRLA AGM battery volt polska OPTI 12V 150 Ah (6AKUV150AG) for standby and deep-cycle use

The Sealed VRLA AGM battery 12V 150 Ah from volt polska, model OPTI, is a maintenance-free lead-acid battery designed for both standby and deep-cycle use. Constructed with absorbed glass mat (AGM) technology and a sealed, spill-proof case, the battery is intended for applications where reliable power backup and energy storage are required. Rated for long float service and capable of occasional deep discharges, this 12V 150 Ah unit suits installations that demand stable voltage, low self-discharge and minimal maintenance.

Advantages

This AGM battery provides a sealed, maintenance-free design that eliminates the need for electrolyte topping and reduces installation constraints. Its VRLA construction ensures spill-proof operation and safer handling in confined or vertical installations. The absorbed glass mat plates improve cycle life compared with conventional flooded lead-acid types, offering consistent performance for float charging and intermittent deep-discharge cycles. The battery delivers steady voltage under load and has low self-discharge, which helps preserve stored energy during long standby periods.

Suitable for

• Uninterruptible Power Supply (UPS) systems for data centres and IT equipment
• Telecommunications backup and base station power
• Solar energy storage and off-grid systems
• Mobility and electric vehicles requiring deep-cycle capability
• Emergency lighting and security systems

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 150 Ah (at specified discharge rate)
• Battery type: Sealed VRLA, AGM
• Designed use: Standby (float) service and deep-cycle operation
• Construction: Spill-proof, maintenance-free sealed case
• Performance characteristics: Low self-discharge, suitable for long float periods

How to use

Install the battery in a well-ventilated, dry location on a stable, non-conductive surface and secure it to prevent movement. Connect using appropriately rated cables and terminals, observing correct polarity. Charge and maintain the battery using a charger or system configured for sealed lead-acid/AGM batteries with appropriate float voltage settings to avoid overcharging. For deep-cycle operation, follow the charger manufacturer’s recommended charge profiles and allow controlled recharge after discharge to maximise cycle life.

Usage recommendations

To ensure long service life, avoid prolonged storage at full charge or at deeply discharged states and perform periodic voltage checks during storage. Use a compatible charger with temperature compensation where possible, and follow installation guidelines for ventilation and secure mounting. Replace batteries as part of scheduled maintenance if capacity decline impacts system reliability.
