How do I safely replace the battery in my Eterna PRCIRMW3 LED Circular Bulkhead?

Replacing the battery in your Eterna PRCIRMW3 LED Circular Bulkhead requires following these steps for safety and proper function. Always begin by switching off the electricity at the mains, including both the permanent live and switch live, and allow the existing batteries to completely discharge. Once this is done, you can proceed with the replacement. First, remove the diffuser. Then, take the battery case out of the gear tray and remove the old battery, carefully cutting the wires. Before installing the new battery, write the current date on it. Next, fit the new 3.2V 1500mAh Lithium battery, ensuring you use a suitable connector. After the new battery is in place, refit the gear tray and the diffuser. Restore the power supply and allow the unit to charge for 24 hours. Following the replacement and charging, it's essential to perform a comprehensive operation check and update your test record. If, after following these steps, the light does not remain lit for a full 3-hour test period, consider the need for further inspection. Remember to allow the unit to charge for a full 24 hours after the replacement is complete.
