Tridonic PACK-LiFePO4 4.5Ah 3 CON Emergency Battery Pack – 28003806

The Tridonic PACK-LiFePO4 4.5Ah 3 CON is a rechargeable lithium iron phosphate battery pack designed for compatible Tridonic emergency-lighting control gear.

The pack contains three 1.5Ah LiFePO4 cells connected in parallel, providing a total rated capacity of 4.5Ah at a nominal voltage of 3.2V. Because the cells are connected in parallel, their capacities combine while the nominal pack voltage remains 3.2V.

Unlike Tridonic’s stick and side-by-side battery arrangements, the 28003806 is supplied in a protective remote-box enclosure. This makes it suitable for luminaires where the battery must be positioned separately from the emergency driver or where a contained battery arrangement is preferred.

The battery incorporates protective electronics for deep discharge, overcharging, short circuits and excessive temperature. Its LiFePO4 chemistry provides good energy density, low self-discharge and a long expected service life when installed, commissioned and maintained correctly.

This battery must only be used with Tridonic emergency-lighting equipment that specifically lists part number 28003806 as an approved battery option. Compatibility and the resulting emergency duration depend on the connected emergency driver.

COMPATIBILITY

The 28003806 is intended only for compatible Tridonic emergency-lighting control gear.

Compatibility must be confirmed using the current Tridonic battery-assignment table for the relevant emergency driver. The required battery depends on:

• Emergency-driver model


• Required one-hour, two-hour or three-hour duration


• Emergency output power


• LED-module voltage


• Permitted battery capacity and configuration


• Connector arrangement


• Available installation space

Do not select this battery solely because another battery has the same nominal voltage or capacity.

The 28003806 appears as an approved battery option for selected Tridonic EM converterLED products, including certain BASIC, SELFTEST and PRO models. Approval varies by driver model and required duration.

INSTALLATION AND COMMISSIONING

This battery is intended for installation by a competent person inside or alongside a suitable emergency luminaire.

The battery should be securely mounted away from excessive heat, sharp edges and components likely to damage the enclosure or connecting cable.

Only connect the battery to a compatible Tridonic emergency-lighting unit. The connector must not be modified or forced into incompatible control gear.

New LiFePO4 batteries may require two or three complete charging and discharging cycles to achieve their full rated capacity. Each activation cycle should include:

1. A complete 24-hour charge


2. A full emergency-duration discharge


3. A further complete recharge

If the first full-duration test is unsuccessful, recharge the battery for 24 hours and repeat the test.

Avoid repeatedly cycling the battery during building installation or commissioning. Keep it disconnected until a stable, permanent mains supply is available.

STORAGE INFORMATION

• Store in the original packaging.


• Keep the battery disconnected during storage and transportation.


• Store in a dry, low-humidity environment.


• Recommended storage temperature: −20°C to +35°C.


• Recommended relative humidity: 60% ±5%.


• Avoid corrosive gases, direct sunlight and excessive heat.


• Do not store the battery in a discharged condition.


• Recharge within the period specified by Tridonic.


• Do not leave the battery connected to an unpowered emergency driver for an extended period.

BATTERY SAFETY

• Use only with emergency equipment approved by Tridonic.


• Do not short-circuit the battery terminals.


• Do not open, dismantle, crush, puncture or modify the battery pack.


• Keep the battery and connecting cable away from sharp edges.


• Do not expose the battery to fire, excessive heat or direct sunlight.


• Protect the battery from moisture and water.


• Transport and store it in its original packaging.


• Follow the applicable lithium-battery transport requirements.


• Replace any damaged, swollen, leaking or overheated battery immediately.


• If battery fluid makes contact with skin, rinse thoroughly with water and seek medical advice where necessary.


• Dispose of the battery through an authorised battery-recycling facility.


• Do not dispose of it with general household or commercial waste.

IMPORTANT COMPATIBILITY INFORMATION

The 28003806 is a 3.2V battery pack containing three parallel cells. It must not be confused with a three-cell series battery.

Connecting it to equipment requiring a different voltage, cell arrangement or battery-management system may damage the battery or emergency control gear and could create a safety risk.

Always verify the exact Tridonic article number in the emergency driver’s current technical documentation before ordering or installation.
