Sealed AGM Rechargeable Battery Technocell TCL12-12 12V 12Ah

Technocell TCL12-12 is a sealed AGM rechargeable battery with a nominal voltage of 12V and a rated capacity of 12Ah. The valve‑regulated, maintenance‑free construction uses absorbent glass mat (AGM) technology to immobilize electrolyte, providing spill‑proof operation and reliable standby performance for compact installations. The battery is intended for standby power and predictable cycling in applications such as alarm systems, uninterruptible power supplies (UPS), emergency lighting and other small DC devices.

Advantages

The sealed AGM design offers maintenance‑free operation and reduced risk of leakage compared with flooded lead‑acid batteries. Its valve‑regulated construction minimizes water loss and extends usable shelf life when stored correctly. Compact dimensions and a low self‑discharge rate allow flexible placement in cabinets and enclosures while maintaining readiness for standby use. The battery supports predictable cyclic performance and consistent voltage output under typical load conditions.

Suitable for

• Alarm and security systems
• Small UPS units and backup power modules
• Emergency and exit lighting
• Telecommunications and monitoring equipment
• Portable DC devices requiring sealed lead‑acid power

How to use

Install the battery in a clean, dry, well‑ventilated enclosure and connect using appropriately rated terminals and cables. Ensure correct polarity when making connections and follow the host device instructions for charging and commissioning. Use a charger compatible with sealed lead‑acid/AGM batteries and apply the recommended charging voltage and current profile to avoid overcharge. For standby applications, maintain a regular inspection schedule to check terminal tightness and cleanliness; for cyclic use, follow the equipment manufacturer’s cycle‑charge recommendations.

Usage recommendations

Store the battery at moderate temperatures and recharge every few months if kept in storage. Avoid deep discharges where possible to prolong service life. Replace the battery at the end of its rated life or when capacity falls below application requirements. Dispose of used batteries according to local regulations for lead‑acid batteries.
