These replacement battery hatches are designed specifically to restore the battery compartment seal on the Laerdal CPRmeter 2 feedback device. Made from high-density, impact-resistant composite, these caps feature internal metal contacts to ensure constant electrical flow from the batteries. They are offered in two specific configurations to match different hardware requirements: Model A includes flexible safety lanyards to prevent the caps from dropping during field changes, while Model B offers a clean, standard cap layout without a lanyard attachment.

Both configurations are packaged as convenient multi-unit replacement packs, allowing training centers to maintain their devices in working order.
