Veo 180

[Centrals]

Few questions on the unit:
1. The unit would only switch off when the "No Fly" has wind down to ZERO. WHY?
2. After one dive the battery has drained from full to low(battery sign flashing)!!
Would a change of battery alleviate the problem? Or the unit is faulty?

I really do not understand why it is necessary for the unit to remain switch on for over 24hrs after just one dive.
When I switched on the unit to change the settings, it will take 2hrs for the unit to switch itself off.

Changing battery too often is asking for trouble.

My 180 NX turns itself off well before the No Fly hits zero. After diving it is usually off by the time I finish breaking down my gear. I can hit the button to wake it up and check the stats.

Sounds like something may be wrong with the unit

Thank you.
So it is normal for the "No Fly" to count down to ZERO or another dive is made!! What a waste of battery power!!!!!
Another interesting point is that even dived on gauge mode, it still gives NO Fly warning afterwards!!

I bought this unit recently on line so I will ask for a new battery + O-ring or a new replacement. I use this unit as a back up for my ageing Aladin which has never given me any problem over last 19yrs!

I have a similar unit, Veo 200, and the battery indicator is crap (problem with measuring any Li battery) so you get little or no warning when it goes bad. If any problem presents itself, change the battery.

I clean and lightly lube the o-ring and reuse it a number of time before it is replaced. I have made a point in going to a store that turns over a lot of those batteries because I've had them go bad shortly out of the package. I replace the battery before a major trip so I don't have to change it in a rush in less than optimal conditions and I carry an extra at all times.


Good luck

The battery indicator in Aladin is also not accurate but I only have to renew it every 3-4 yrs.
Oceanic also recommend to renew the battery before every trip.

I have used Veo 180's and now use Veo 250's. The no fly stays alive for 24 hours but I don't think it has a major affect on battery life. I change them about once a year, whenever the battery status is not clear full. What a pain to change! Are you sure the battery compartment isn't flooded? That will cause a rapid battery failure.

This is a brand new unit so I am not going to open it. I am waiting for the instruction from the on-line retailer. I am NOT looking forward to replace the battery from what I had heard.
I fail to see the logical reason to have the computer on for 24hrs in order to wind down the No Fly penalty! It serves no purpose whatsoever.

The problem with Li batteries is that the are made to maintain voltage throughout their life, what happens is they can no longer produce the current to run the unit. Battery life meters are voltage meters and work fine on batteries that decrease their voltage over their life. that is why you get little or no warning before the Li battery is shot. The Veo can run a long time on a battery, I usually change it once a year for my "big" trip, and the only thing that seems to wear it out faster is the backlight, and I'm not sure if it's that or an off battery.

The battery replacement is easy, follow the instructions and have the other battery ready for the switch so you minimize the time. The cover does not take the battery out of the circuit, only physically removing it does. Make sure the o-ring is clean and take your time seating it before you place the cover and close it up. If you don't have the pin spanner "key" get one as it will make your life easier.

It is not just running the no-fly clock. It is also doing desaturation computations until you "finish" off-gassing. If you load up the really slow compartments, that process may run well beyond the 24 hour no-fly time.

Load up a 12 hour (720 minutes) compartment and if it take 6 half-lifes to consider that compartment off-gassed, that is 3 days.
