Description

The LSU NiMH Battery is a specialized rechargeable power source crafted by Laerdal, tailored specifically for the Laerdal Suction Unit (LSU) and the Laerdal Compact Suction Unit 4 (LCSU 4). This nickel-metal hydride (NiMH) battery is engineered to provide consistent and reliable performance, ensuring that critical medical devices remain operational when needed most.

Key Specifications

• Nominal Voltage: 12 V
• Capacity: 2 Ah
• Dimensions:
• Height: 3 cm (1.18 in)
• Width: 7 cm
• Length: 19 cm (7.5 in)
• Weight: 0.37 kg (0.81 lb)

Environmental Benefits

The LSU NiMH Battery is designed with environmental responsibility in mind. It contains no toxic cadmium and is mercury-free, making it easier to recycle compared to traditional NiCad batteries. The absence of heavy metals aligns with EU Directive 2006/66/EC, and it is marked with the crossed wheel bin symbol to promote proper disposal and recycling.

Performance and Storage

This battery offers long-lasting durability and is not considered a water hazard under normal conditions. It performs optimally when stored at room temperature, with recommended storage conditions ranging from -20°C to 35°C. Charging is best conducted between 15°C and 25°C. At lower temperatures, performance may be affected, particularly at high vacuum levels, but normal functionality resumes once the battery warms up.

Handling and Safety

Proper handling is crucial for maintaining the battery's integrity. It should not be opened, burned, or short-circuited. Disposal should adhere to local regulations, with recycling strongly encouraged. Under normal use, the battery does not release hazardous chemicals and is not classified as hazardous waste in the USA.

Transport Considerations

For transport, the battery is classified under 'Batteries, nickel-metal hydride, UN 3496'. It is generally unregulated by major international transport authorities when properly packed. Packaging must prevent short circuits, mechanical damage, and moisture ingress, in line with IEC 62133 standards.

Operational Note

A notable operational consideration is its performance at temperatures between 0°C and 9°C. Under these conditions, the battery may cause the LSU to shut off unexpectedly at high vacuum levels. Users are advised to operate at reduced suction levels or allow the battery to reach room temperature to mitigate this issue.

The LSU NiMH Battery stands as a robust and eco-friendly power solution, integral to the functionality of Laerdal's medical suction devices, with clear guidelines for optimal use and handling.
