We have received over the last four weeks numerous dive computers of different brands with the unpopular “ERR” Display Reading.
Most customer complaints were “Computer eats Batteries” – or high power consumption in technical terms.
The units were tested for power consumption which in rare cases can drain the batteries and needs internal fixing. Two units were identified with abnormal high consumption. None needed a PCB repair.
In both cases salt & mineral build-up on the wet contacts (see picture) were responsible for draining the power within days. The owners would have saved a lot of headache and some batteries by proper rinsing and cleaning the computer after diving. Of the eight remaining computers one was fitted with the wrong size/type battery, explaining the malfunction.
The remaining seven units all came with the same brand of battery.
I don’t really want to mention which brand it is as I think that all are fakes and not the original branded.
All were CR2450 and were supplied by the same source. So if your computer runs out of battery much faster than acceptable it might need some attention and a brand new, genuine or branded power-source.
