Sealed AGM Lead-Acid Battery Technocell TCL26-12 12V 26Ah — maintenance-free power source

Technocell TCL26-12 is a sealed AGM lead-acid battery with a nominal voltage of 12V and a capacity of 26Ah. The valve-regulated, absorbed glass mat (AGM) design provides a maintenance-free rechargeable power source that prevents electrolyte leakage and supports installation in multiple orientations. The battery is intended for both standby and cyclic use, delivering dependable energy for systems that require reliable backup or portable power without routine servicing.

Advantages

The sealed AGM construction ensures low self-discharge and eliminates the need to add water or perform regular maintenance. Valve regulation maintains safe internal pressure and reduces the risk of spillage, enabling flexible mounting positions. The battery's 12V/26Ah rating offers a balance between compact size and usable energy capacity suitable for a range of small to medium loads. Robust internal plate design and AGM separators improve vibration resistance and support repeated charge/discharge cycles.

Suitable for

• Uninterruptible power supplies (UPS) for home or small office equipment
• Alarm and security systems
• Emergency and exit lighting systems
• Portable or small renewable energy systems (charge controllers, small inverters)
• Mobility devices and small electric vehicles (wheelchairs, scooters) requiring a compact 12V battery

Key specifications

• Nominal voltage: 12 V
• Capacity: 26 Ah (at specified discharge rate)
• Battery type: Sealed lead-acid, AGM (absorbed glass mat)
• Maintenance: Maintenance-free, valve-regulated
• Mounting: Can be installed in different orientations (consult device manual for limitations)

How to use

Install the battery in a clean, dry, and well-ventilated area, following the equipment manufacturer's instructions for polarity and terminal connections. Use compatible chargers or charging systems configured for sealed lead-acid AGM batteries and observe recommended charge voltages and temperature compensation where applicable. For standby systems, keep the battery on float charge per the system's specifications; for cyclic use, follow the recommended charge/discharge profiles to maximize cycle life. Avoid short circuits and ensure terminals are protected from conductive debris.

Usage recommendations

Store and operate the battery within recommended temperature ranges to preserve capacity and service life. Periodically check charge status and terminal condition; clean terminals and ensure secure connections. Replace the battery when end-of-life capacity or internal resistance indicates insufficient performance for the intended application.
