Sealed Lead-Acid VRLA AGM Battery CARSPA MS4.5-6 6V 4.5Ah for UPS and Backup Power

CARSPA MS4.5-6 is a sealed lead‑acid VRLA AGM battery with a nominal voltage of 6V and a capacity of 4.5Ah. The battery features a compact, robust construction designed for applications that require reliable short‑term power in confined spaces. It is maintenance‑free, hermetically sealed and can operate in any orientation, making it suitable for UPS, backup power systems, alarm panels, small electronics and marine installations where liquid electrolytes or vibration can be a concern.

Advantages

The VRLA AGM construction delivers low internal resistance for high discharge currents, increased vibration and shock resistance, and longer service life compared with many conventional lead‑acid designs. The stronger container materials and sealed design prevent leakage and allow operation in tilted or vertical positions. Its size‑to‑capacity ratio provides good power output relative to footprint, useful for starting and high‑current devices like inverters and starters.

Suitable for

• Uninterruptible power supplies (UPS)
• Backup power systems and emergency circuits
• Alarm and security panels
• Small inverters and starters requiring high discharge current
• Solar and standby power installations
• Marine and mobile equipment where tilt and vibration occur

How to use

Install the CARSPA MS4.5-6 in accordance with the equipment manufacturer’s instructions, observing correct polarity and secure terminal connections. Use an appropriate charger or charging circuit designed for sealed lead‑acid AGM batteries and avoid overcharging. The battery may be mounted in any orientation; ensure adequate ventilation and protect from sustained high temperatures. For UPS or backup systems, follow the system’s maintenance and testing schedule to verify charge state and readiness.

Usage recommendations

For long service life, store and operate the battery at moderate temperatures, keep it charged when not in use, and use a charger with an AGM/VRLA charging profile. Avoid deep discharges whenever possible and replace the battery if capacity noticeably decreases.
