Description

This 3.6V 1800mAh nickel-cadmium rechargeable battery is designed for series connection in Duceri emergency lighting systems. The battery pack consists of three individual cells sealed in a white cylindrical housing, with red (positive) and black (negative) wiring terminating in a white connector plug. CE certification and recycling symbols are printed on the casing.

Emergency lighting systems require batteries that can hold a charge over extended periods and deliver reliable output when mains power fails. Nickel-cadmium chemistry provides consistent voltage delivery across the discharge cycle and can be recharged hundreds of times without significant capacity loss. This battery is specifically rated for series connection, meaning it connects in line with other batteries to build up higher system voltages while maintaining the 1800mAh capacity.

The battery measures approximately 200mm in length and weighs 143g, making it compact enough to fit inside typical emergency light housings without adding excessive weight. The sealed construction prevents leakage and the pre-fitted connector eliminates the need for soldering or crimping during installation. The red and black wire colour coding matches standard UK electrical practice, reducing the risk of reverse-polarity errors during fitting.

Frequently Asked

What does 'series connection' mean?

Series connection means this battery connects end-to-end with other batteries to increase the total system voltage while keeping the same capacity. For example, two 3.6V batteries in series produce 7.2V at 1800mAh, three produce 10.8V at 1800mAh, and so on.

How long does the battery last before needing replacement?

Nickel-cadmium batteries typically provide 500-1000 charge/discharge cycles before capacity drops noticeably. In emergency lighting applications where the battery is trickle-charged continuously and only discharged during power cuts or monthly tests, this translates to several years of service life depending on usage patterns.

Is the connector compatible with Duceri emergency lights?

Yes, the white connector plug is designed to fit Duceri emergency lighting units. The connector eliminates the need for hardwiring and allows the battery to be replaced without tools or electrical skills beyond isolating the unit from mains power.

Can this battery be used in other applications besides emergency lighting?

While the battery is rated for emergency lighting, any application requiring 3.6V rechargeable power with series connection capability can use it. However, the charge controller and discharge profile must be compatible with nickel-cadmium chemistry to avoid damaging the cells or reducing lifespan.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund. Customers pay return shipping. Made-to-order, special-order and clearance items cannot be returned. See full returns policy.
