Sealed AGM Rechargeable Battery QOLTEC 6V 4.5Ah, max. charge current 1.35A

Sealed AGM rechargeable battery QOLTEC 6V 4.5Ah is a valve‑regulated lead‑acid (VRLA) unit designed for standby and cyclic use. The battery provides a rated capacity of 4.5Ah at 6V and is built with absorbent glass mat (AGM) technology to ensure maintenance‑free operation, low self‑discharge and consistent voltage output. Its compact sealed design makes it suitable for installation in confined spaces where spill‑free, reliable power is required.

Advantages

The AGM construction delivers good charge acceptance and low internal resistance, enabling stable performance under varying loads. Being sealed and valve‑regulated, the battery does not require water topping and reduces the need for routine maintenance. Low self‑discharge helps retain capacity during storage or infrequent use. The battery supports both standby applications where it maintains a charge until required and cyclic applications with repeated charge and discharge cycles when used within the recommended limits.

Suitable for

• Alarm and security systems
• Uninterruptible power supplies (UPS) for small devices
• Emergency lighting and exit signs
• Electronic toys and ride‑on devices
• Small electronics, sensors and measurement equipment

Key specifications

• Nominal voltage: 6 V
• Rated capacity: 4.5 Ah (at specified discharge rate and temperature)
• Battery type: Sealed AGM (VRLA)
• Maximum recommended charge current: 1.35 A
• Construction: Non‑spillable, valve‑regulated lead‑acid cells
• Typical applications: Standby and cyclic use

How to use

Install the battery in a suitable holder or compartment with correct polarity. Connect to the host device or charger following the device manufacturer’s wiring diagram. Charge the battery using a charger designed for sealed lead‑acid/AGM batteries, observing the maximum recommended charge current of 1.35 A and appropriate charge voltage for 6 V batteries. Avoid deep discharges and ensure the battery operates within the ambient temperature range specified by your equipment to maximize life. When replacing an existing battery, match nominal voltage and capacity to maintain system performance.

Usage recommendations

Store batteries in a cool, dry place and recharge periodically if kept in storage. Use a compatible AGM/VRLA charger with correct voltage regulation and temperature compensation where applicable. Do not short‑circuit terminals or expose the battery to open flame. Dispose of the battery according to local regulations for lead‑acid batteries.
