Temporary Voluntary Certificate Suspension

Update 26th March 2024

In addition to information previously shared we can advise that in an isolated incident, one caplamp battery experienced a thermal event whilst on charge above ground. Our investigations remain ongoing.

Update 19th March 2024

As our investigation continues, there is no evidence to suggest that batteries manufactured prior to Denchi acquiring the Oldham Caplamp brand are unaffected.

These batteries may have been placed on the market using a numbering scheme different to that used by Denchi.

Additional Part Numbers to be considered: M456623, M456323, M456723, M456823, M456523

Initial Bulletin 12th March 2024

In accordance with IECEx OD 209 Ed 1.1 Clause 4.2.1, a request has been made to initiate voluntary suspension of Certificate of Conformity ANZEx 07.4049X [Lithium-ion L16 battery], effective from 8th March 2024. Manufacturing of the L16 battery has been voluntarily suspended from 1st March 2024, which preceded suspension of the Certificate of Conformity.

The affected product is: L16 Lithium-ion Caplamp Battery
Part numbers: 203000, 203002, 203012

A potential manufacturing defect has been identified which may cause inadvertent internal short circuit and may result in unacceptable heating of the PCB. The defect introduces a possible ignition source although likelihood and frequency of occurrence remain unclear at this time.

An abundance of caution is being exercised in suspending this Certificate of Conformity pending investigation.

Collaboration with the regulator and certifying body is ongoing to assist investigations and obtain timely conclusions.
