Description
The Duceri 4.8V 1800mAh is a nickel-cadmium rechargeable battery pack configured in series, delivering 4.8V nominal voltage at 1800mAh capacity. The pack consists of four individual NiCd cells connected in series and wrapped in white heat-shrink tubing, with red and black wire leads terminating in a pre-fitted connector for direct installation into compatible emergency lighting units and exit signs.
Designed as a replacement battery for emergency lighting systems, exit signs, and backup lighting installations that require 4.8V NiCd chemistry, the pack provides standby power during mains failure. The 1800mAh capacity supports typical 3-hour emergency lighting run times when paired with LED or low-wattage lamp loads. The series configuration means the cells charge and discharge together as a single unit, simplifying installation and reducing the risk of cell imbalance over repeated charge cycles.
The pack measures 200mm in length, making it compatible with standard emergency lighting battery compartments in UK and European exit signs. NiCd chemistry tolerates deep discharge cycles better than NiMH alternatives and can be stored for extended periods without significant capacity loss, making it suitable for infrequently-used standby systems. The pre-fitted connector matches common emergency lighting battery sockets, though compatibility should be verified before purchase as connector types vary between manufacturers.
The 191g weight keeps the pack light enough for wall-mounted emergency units without requiring additional structural support. NiCd batteries contain cadmium and must be disposed of through dedicated recycling streams — do not discard with general household waste.

Frequently Asked
What type of emergency lighting units does this battery fit?
The 4.8V 1800mAh configuration suits emergency lighting units and exit signs that specify NiCd chemistry at this voltage and capacity. The 200mm length and pre-fitted connector match many UK and European emergency lighting systems, but connector types vary between manufacturers — verify compatibility with your specific unit before ordering.
How long does the battery run emergency lights for?
Runtime depends on the lamp load. At 1800mAh capacity, the pack typically supports 3-hour emergency lighting operation with LED or low-wattage loads (6-10W combined). Higher loads reduce runtime proportionally.
Can this replace a NiMH battery of the same voltage?
NiCd and NiMH batteries have different charging profiles and voltage curves. Replacing a NiMH battery with NiCd requires that the charging circuit is compatible with NiCd chemistry — using the wrong battery type can damage the charger or battery. Check your emergency lighting unit's manual before substituting.
How should used NiCd batteries be disposed of?
NiCd batteries contain cadmium and are classified as hazardous waste. Take used packs to a local recycling centre that accepts batteries, or return them to a retailer offering battery recycling. Do not place in household waste bins.
