Tridonic ACCU-LiFePO4 7.5Ah 5A CON Emergency Lighting Battery – 28002325

The Tridonic ACCU-LiFePO4 7.5Ah 5A CON is a rechargeable lithium iron phosphate battery designed for use with approved Tridonic emergency-lighting control gear.

Its five cells are arranged in one long, slim stick measuring approximately 354 mm. This linear arrangement is suitable for compatible luminaires that provide sufficient length but have limited width or height. The battery pack has a rated voltage of 3.2 V and a total rated capacity of 7.5 Ah.

Integrated electronics provide deep-discharge, overcharge and short-circuit protection. A built-in thermal sensor supports safe charging and helps protect the battery when connected to compatible Tridonic emergency control gear.

LiFePO4 technology provides high energy density, reliable high-temperature performance and good charge retention. Under suitable installation, charging and temperature conditions, the battery offers a design life of up to 12 years.

A plug-in connection simplifies installation and replacement. The battery must only be used with Tridonic emergency-lighting units that specifically approve article 28002325 or its battery type, capacity and configuration.

INSTALLATION AND COMMISSIONING

The battery must be connected only to compatible Tridonic emergency-lighting control gear.

For a new battery to reach its rated capacity, Tridonic specifies two to three complete activation cycles. Each cycle consists of:

• A complete 24-hour charging period


• A complete emergency-duration discharge


• Recharging before the next discharge cycle

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

Install the battery away from heat sources and within the temperature limits specified for the associated emergency driver. During construction or commissioning, leave it disconnected until a stable, continuous mains supply is available.

Do not leave the battery connected to an unpowered emergency unit for an extended period. Excessive cycling or prolonged storage in a discharged condition can significantly reduce battery life.

IMPORTANT COMPATIBILITY INFORMATION

Check the current datasheet for the connected Tridonic emergency unit before ordering. Matching the connector alone does not confirm electrical compatibility.

Confirm all of the following:

• Tridonic article number 28002325


• 3.2 V battery requirement


• 7.5 Ah rated capacity


• Five-cell linear configuration


• Connector type and polarity


• Available space for the 354 mm battery


• Required emergency duration


• Approval for use with the exact emergency driver

Emergency duration depends on the emergency control gear, LED load and system configuration. This battery must not be connected to third-party charging equipment or used as a general-purpose rechargeable battery.

SAFETY INFORMATION

• Do not short-circuit, open, crush or damage the battery


• Keep away from water, moisture, direct sunlight and excessive heat


• Keep the battery and its cables away from sharp edges and heat sources


• Do not throw the battery into a fire


• Disconnect it during extended luminaire storage


• Transport and store it in its original packaging


• Do not use a damaged or leaking battery


• Follow applicable lithium-battery transport requirements


• Dispose of it through an approved battery-recycling facility


• Do not place it in general household or commercial waste


• Opening the battery invalidates the manufacturer’s warranty

COMPARISON WITH RELATED 7.5Ah VERSIONS

• 28002325 – 5A: Five cells in one linear stick, approximately 354 × 22 × 24 mm


• 28002326 – 5B: Five cells in a compact side-by-side arrangement, approximately 92 × 72 × 19.5 mm


• 28002327 – 5C: Five cells divided into 3+2 separate sticks; longest section approximately 223 × 22 × 24 mm

All three versions provide a 7.5 Ah capacity, but their physical arrangements differ. Select the configuration approved for the emergency driver and suited to the available luminaire space.
