Description

This 3.6V 1800mAh nickel-cadmium rechargeable battery is designed as a replacement power pack for Duceri emergency lighting units, specifically the EM3WNMDLK, EM3WNMCDLK and EMD3WNMDLK models. The battery pack consists of sealed nickel-cadmium cells configured to deliver 3.6V nominal voltage with 1800mAh capacity, providing backup power to emergency exit signs and emergency lighting heads when mains power fails.

Emergency lighting regulations in the UK require that battery-powered emergency lights maintain illumination for a minimum duration during power outages, typically 3 hours for most commercial and residential applications. This 1800mAh capacity supports that requirement in compatible Duceri units. The battery connects via the pre-wired red (positive) and black (negative) leads terminating in a connector that matches the Duceri units' internal socket, allowing straightforward replacement without rewiring.

Nickel-cadmium chemistry offers reliable cycling performance across repeated charge-discharge cycles, maintaining capacity over the typical 3-5 year service life of emergency lighting batteries. The sealed construction means the battery requires no maintenance beyond periodic testing of the emergency lighting unit itself. The 200mm length allows the battery to fit within the compact housing of Duceri emergency light fittings without modification. CE marking confirms compliance with EU safety and electromagnetic compatibility standards.

Frequently Asked

Which Duceri emergency lights is this battery compatible with?

This battery is a direct replacement for Duceri models EM3WNMDLK, EM3WNMCDLK and EMD3WNMDLK. The pre-wired connector matches the internal socket on these units. If you have a different Duceri model, check the existing battery voltage and capacity before ordering.

How long does the battery last before needing replacement?

Nickel-cadmium emergency lighting batteries typically provide 3-5 years of service life depending on the frequency of discharge cycles and ambient temperature. UK regulations require testing emergency lights monthly and conducting a full duration discharge test annually, which helps identify when battery capacity has degraded below the required threshold.

Can I fit this battery myself?

Replacing an emergency lighting battery involves working with mains-connected equipment. If you are not a qualified electrician or competent person under the Electricity at Work Regulations, the replacement should be carried out by a qualified professional. The battery itself is plug-and-play via the pre-wired connector.

Does the battery come pre-charged?

Nickel-cadmium batteries are typically supplied with a partial charge. Once fitted into the emergency light unit and connected to mains power, the unit's internal charging circuit will bring the battery to full charge over the following 24-48 hours.
