Lead-acid VRLA AGM battery CARSPA Pb Battery MHPower 6V 4Ah (sealed, maintenance-free)

Sealed CARSPA Pb Battery MHPower VRLA AGM 6V 4Ah is a valve-regulated lead-acid battery with a nominal voltage of 6 V and a capacity of 4 Ah. It is manufactured with a reinforced container and AGM (Absorbed Glass Mat) technology, producing a compact, spill-proof and maintenance-free unit intended for standby and cyclic applications such as UPS, alarm systems, emergency lighting and small equipment.

Advantages

The MHPower construction offers extended service life compared with many conventional batteries, greater resistance to shocks and vibration, and a higher power-to-size ratio. Its sealed AGM design allows operation in any orientation without leakage and reduces maintenance needs. Low internal resistance supports high discharge currents, making it suitable for starting and inverter applications as well as backup power.

Suitable for

• Uninterruptible Power Supplies (UPS) for small systems
• Alarm and security systems
• Emergency and exit lighting
• Small inverters and DC–DC converters
• Solar and other standby power installations

When it may not be suitable

This sealed 6 V/4 Ah battery is designed for low-to-moderate capacity backup and cyclic use; it may not be suitable where very high capacity or long runtime is required. It is not intended for open-cell or flooded battery applications and should not be used where specific OEM codes or custom form factors are required.

How to use

Install the battery in a compatible holder or compartment, observing correct polarity. Use a charger or charger mode compatible with 6 V VRLA/AGM batteries and follow manufacturer charging recommendations. For standby installations, connect to the device according to its wiring diagram and test regularly. The sealed design allows installation in different orientations, but ensure adequate ventilation and avoid exposure to extreme heat or direct flame.

What to consider before purchase

• Confirm that 6 V nominal voltage and 4 Ah capacity meet your runtime and load requirements
• Ensure physical dimensions (70 × 47 × 101 mm) and terminal types fit your equipment
• Verify charger compatibility with VRLA AGM batteries
• Consider expected discharge currents and required cycle life for your application

Usage recommendations

Charge with a VRLA/AGM-compatible charger, avoid deep discharges when possible, and store the battery charged in a cool, dry place to maximise service life.
