Lead-acid VRLA AGM battery CARSPA MS65-12 12V 65Ah (maintenance-free)

Sealed lead-acid VRLA AGM battery CARSPA MS65-12 delivers 12 V nominal voltage and 65 Ah capacity in a maintenance-free, valve-regulated design. The compact sealed construction makes it suitable for standby and cyclic applications where a reliable, spill-proof power source is required. Low self-discharge and an AGM electrolyte arrangement provide stable performance in UPS systems, alarm and security installations, telecom cabinets and other backup power setups that demand safe, upright installation and predictable discharge characteristics.

Advantages

The CARSPA MS65-12 offers maintenance-free operation with a valve-regulated sealed design that reduces the need for service and prevents electrolyte leakage. Absorbent Glass Mat (AGM) technology improves charge acceptance and minimizes self-discharge, ensuring longer shelf life and reliable capacity when called upon. The battery is designed for both cyclic and standby use, providing consistent output and tolerance to repeated charge–discharge cycles. Its compact dimensions allow installation in constrained spaces typical for UPS and telecom racks.

Suitable for

• Uninterruptible Power Supply (UPS) systems for servers and IT equipment
• Alarm, access control and security systems
• Telecommunication cabinets and network equipment backup
• Emergency lighting and safety systems
• Standby and cyclic power applications in small equipment enclosures

How to use

Install the battery in a well-ventilated, dry location designed for sealed lead-acid batteries, observing correct polarity and secure terminal connections. Use a compatible charger or UPS charging system configured for 12 V VRLA batteries and follow the charger manufacturer’s voltage and current settings for float and cyclic charging. Avoid deep discharges beyond the recommended depth of discharge for prolonging cycle life and restore full charge after use to prevent sulfation. Regularly inspect connections and the installation environment for temperature extremes, which can affect battery performance and life.

Usage recommendations

For optimal service life, maintain charging system settings appropriate for VRLA/AGM batteries, avoid prolonged storage in a discharged state, and operate within recommended temperature ranges. Replace batteries showing significant capacity loss or repeated inability to achieve full charge.
