One of our Members has reported that on one of their vessels they found that the battery to the lifejacket had swelled out, resulting in a ruptured battery.

The maker of the battery is McMurdo and the expiry date was January 2002. Below is a picture of the ruptured battery.

When the member alerted its other vessels to this failure, another vessel reported that on checking its lifejackets, two lifejacket lights were found in a similar condition to that above. The expiry dates for their batteries were August 2001 and May 2003.

The member is now in discussions with the manufacturer on this issue.
