Umbilical canister became pressurised during dive - why?

[little nick]

Well good news!

c/10 for 16 hours worked - it ran on the bench for 2 hours with no pressure build up!

Thanks to all your advice !

That's great!

Now as long as you don't discharge it too deeply, it should last a while longer. If you have time, that's the best way to charge it in general.

This is teh way forwards for me - I'll only use the fast charger if I need it (1-2 times a year) & use the wall wart (.5A) for the rest!
Now I have 2 battery packs - so it should never be a problem.

The wall wart - although it claims 12v, is putting out 18v which seems a little high to me. I might need to invest in a smart charger.

If it's really only putting 1/2 amp, it doesn't matter what the voltage is. The cells may be as high as 1.5-1.6V each during charge. But if the current is limited to C/10, you're good until the cells fail.

Thanks - you have been a great help. I assume if will be about .5A - but I can't test it.
