The batteries were duracell brand new reading 1.59 at start of dive
They read 1.4 during the dive. I think they were 1.3 at the end of the dive
The 5 minutes was on 15-12m stop, so no temp change. The temp was about 8 degree's
I didn't notice the voltage reading when the primary came back on.
This is the first time it has happened
It was an inland dive site so no salt.
I have tried my best to find conductive lubricant in the UK.
If anybody can point me in the right direction that would be great.
Ok sounds like the cell was fine.. Take a good look at the positive terminal inside the battery compartment..
there are 2 main types of conductive greases..
the cheapest is Carbon conductive grease and is usually the easiest to locate.. Silver conductive grease is a superior product but since its considerable more expensive you have to look a bit harder for it..
1 tube will last you forever.. you just need a tiny dab.. to install, I usually put a very small amount on the battery cap threads.. and a small dab directly on the battery (both positive and negative).. It may be overkill but I have never had a reset or lockup due to a bad contact on ANY device that I have used this with..
a quick google search came up with a few hits in the uk..

For the aluminum handsets I prefer a compound designed for protecting al like noalox or no-ox-id (both found in electrical supply houses).
The stainless contacts have gone along way to aleviate issues but no mechanical electrical contact is perfect 100% of the time.. so I take an extra step for peace of mind.. The only connection thats reliable 100% of the time is a properly soldered connection..
