## Long description

Technocell TCL28-12 is a sealed AGM lead‑acid battery with a nominal voltage of 12 V and a rated capacity of 28 Ah. It is designed for stationary power applications where a compact, maintenance‑free energy source is required. The battery features a valve‑regulated, spill‑proof construction that supports both standby (backup) and cyclic use, making it suitable for uninterruptible power supplies (UPS), alarm and security systems, telecom equipment, emergency lighting and small off‑grid solar installations.
Advantages
The sealed AGM design provides low self‑discharge, reliable performance in standby and cyclic operation, and reduced maintenance compared with flooded batteries. The valve‑regulated construction ensures safe operation in different mounting positions without electrolyte leakage. Compact dimensions and stable voltage output make this 12 V, 28 Ah battery easy to integrate into cabinets, enclosures and small battery banks. It also offers consistent recharge acceptance and is suitable for long float service in backup systems.
Suitable for
 Uninterruptible power supplies (UPS) for home and small business
 Alarm, access control and security systems
 Telecommunications and network equipment backup
 Emergency and exit lighting
 Small off‑grid solar or hybrid systems and portable power setups
Key specifications
 Nominal voltage: 12 V
 Rated capacity: 28 Ah (at specified discharge rate)
 Battery type: Sealed AGM (absorbent glass mat) lead‑acid
 Construction: Valve‑regulated, spill‑proof
 Intended use: Standby (float) and cyclic applications
 Typical mounting: Horizontal or vertical orientation allowed
 Maintenance: Maintenance‑free (no electrolyte topping up)
How to use
Install the battery in a well‑ventilated, dry location inside an appropriate enclosure or rack, following manufacturer recommendations for terminal connections and polarity. Use compatible chargers or charge controllers set for sealed lead‑acid/AGM charging profiles to ensure correct float and cyclic charge voltages. Avoid deep discharges where possible; recharge the battery promptly after use to extend service life. Ensure proper cable sizing and secure terminal connections to minimize voltage drop and heating.
Usage recommendations
For backup applications, keep the battery on float charge with a thermostat‑compensated charger or a charging system set to the manufacturer’s recommended float voltage for AGM batteries. For solar or cyclic use, configure the charge controller for AGM profile and limit depth of discharge to improve cycle life. Store batteries at partial charge in cool, dry conditions and recharge every few months if left unused.
