Sealed AGM Rechargeable Battery Technocell TC 2,3-12 12V 2.3Ah

Technocell TC 2,3-12 is a sealed AGM rechargeable lead-acid battery with a nominal voltage of 12 V and a capacity of 2.3 Ah. It is designed for reliable standby power and compact energy storage where maintenance-free operation and spill-proof installation are required. The battery uses AGM (Absorbent Glass Mat) technology to immobilize the electrolyte, enabling safe operation in various orientations and reducing the need for regular servicing.

Advantages

The sealed AGM design provides maintenance-free performance and reduced gas emission under normal operating conditions, while offering good low-temperature starting ability and stable voltage delivery during discharge. Its compact dimensions and sealed construction allow for installation in confined spaces and portable devices without liquid leakage risk. The battery supports both cyclic and float charging regimes and is suitable for frequent discharge/recharge cycles within the rated capacity.

Suitable for

• Backup power for alarm systems and security devices
• Small uninterruptible power supplies (UPS) for networking equipment
• Portable medical devices and instrumentation requiring compact batteries
• Emergency lighting and signaling equipment
• Hobby electronics, model devices, and low-power DC applications

• Nominal voltage: 12 V
• Rated capacity: 2.3 Ah (at specified discharge rate)
• Battery type: Sealed lead-acid, AGM
• Charge modes supported: Float and cyclic charging
• Maintenance: Maintenance-free, sealed design
• Mounting: Spill-proof installation; suitable for upright and limited-angle orientations
• Typical use temperature range: Suitable for standard indoor operating conditions (refer to manufacturer for extreme environments)

How to use

Before first use, ensure the battery is charged according to the equipment manufacturer's recommendations or a compatible charger suitable for sealed lead-acid AGM batteries. Install the battery in the device making sure terminal polarity is correct and connections are secure. For standby applications, maintain the battery on float charge to keep it at optimal state of charge. For cyclic applications, follow recommended charge/discharge profiles, avoid deep discharges beyond the rated capacity, and recharge promptly after use to prolong service life.

Usage recommendations

Use a charger with AGM-compatible charge algorithm and appropriate voltage limits. Store the battery in a cool, dry place and keep it charged during storage to prevent capacity loss. Replace the battery when end-of-life capacity falls below the operational requirement for your application.
