## Summary description

12.8V 18Ah LiFePO4 rechargeable battery by t6 power (model T6LFP0003) provides stable DC power for UPS, backup systems, telecoms, and small renewable projects. LiFePO4 chemistry offers long cycle life, thermal stability and consistent voltage. Compact sealed design suitable for rack, cabinet or portable installations where reliable 12.8V power is required.

## Long description

t6 power T6LFP0003 is a rechargeable 12.8V 18Ah LiFePO4 battery designed to deliver stable DC power for UPS units, backup systems, telecommunications equipment and small renewable energy installations. The battery uses lithium iron phosphate chemistry to provide a long cycle life, predictable voltage under load and improved thermal stability compared with many lead‑acid alternatives. Its sealed, compact construction allows installation in racks, cabinets or portable enclosures where reliable 12.8V backup power is required.
Advantages
The LiFePO4 cell chemistry ensures extended cycle life and consistent capacity over hundreds to thousands of cycles while maintaining a relatively low self-discharge rate. The battery’s nominal 12.8V output provides a stable DC source for 12V systems without the weight and maintenance needs of lead‑acid batteries. Its sealed design reduces installation complexity and eliminates frequent topping‑up. The compact form factor supports space-constrained setups and simplifies integration into UPS cabinets, telecom racks and portable power modules.
Suitable for
 Uninterruptible Power Supplies (UPS) for small to medium deployments
 Backup power for network and telecom equipment
 12V DC systems in small renewable installations (solar charge controllers, inverters)
 Portable power stations and field service equipment
 Emergency lighting and security systems
Key specifications
 Nominal voltage: 12.8 V
 Nominal capacity: 18 Ah
 Battery chemistry: Lithium iron phosphate (LiFePO4)
 Form factor: sealed, maintenance‑free rechargeable battery
 Typical operating temperature range: suitable for normal indoor installations (see manufacturer guidelines for extremes)
 Typical applications: UPS backup, telecom power, small renewable energy storage, portable DC power
How to use
Install the battery in a well‑ventilated, dry location within the rated temperature range. Connect to compatible 12.8V charging systems, UPS units or DC loads observing correct polarity. Use a charger or battery management system (BMS) designed for LiFePO4 chemistry to ensure proper charging voltages and cell balancing. For installation in racks or cabinets, secure the battery to prevent movement and avoid short circuits by protecting terminals. Follow the equipment manufacturer’s instructions for series or parallel connections; parallel connection requires matched batteries and an appropriate BMS or charge controller to ensure safe operation.
Usage recommendations
To maximize service life, store and operate the battery within recommended temperature limits, avoid deep discharges when possible, and use a LiFePO4‑compatible charger or a UPS with LiFePO4 charging profile. Periodically inspect terminals and mounting to ensure secure connections and clean contacts.
