Vision-Battery-Problem

Hello!

I've the evolution with the new vision software on it.
I tested the VARTA and the DURACELL batteries with the same result. When i put the new bat. in the handset is showing 5,9-6,0V, under solenoid aktivity 5,4V and after i kalibrate my unit twice and one dive the batterie display lose one Brick of three.

anyone the same problems??

Hi,

How long does the battery last before you need to replace it?

With the latest Vision software the battery display latches the display...meaning once you lose a brick the brick wont come back..even if the voltage level does recover.

I'm curious how long the battery lasts though...if you get good times out of it it sounds like this is just how the software works.

I consistently got 17 hours out of the Duracells with my and my wife's evo's and that was staying well within the apparent voltage limit.

Hello!

I don't know how long the batteries last. But I'll test it.

Everything started in oktober...
I was on a diving trip in kroatia, the first 2 dives were ok but then the trouble began. I was down at 45m when suddenly C1 shut down and the B2 had 1 notch. I had enough bailout with me, so i decided to stay on the loop. After the dive i changed the batteries. The next dive it happened again with new batteries (VARTA usable until 2015).

Befor the last dive at home i used contact spray but i dont thrust the batteries.

I dont know, is it a software or a hardware failure??

I had a strange thing happen on my vision inspo on sat and sunday.

On saterday afternoon i preped my unit ready for sunday, whilst switching on the hand set i was met with a blank B1 slot, with the obligatory no C1 no B1 dive now YES / NO message. ( i always use Fujitsu's )

The odd thing was the battery was fine 3 weeks ago (new) and had only done 8hrs. No worrys i replaced the B1 battery with B2, and put a fresh battery in the B2 slot. Turned on again and all was well, out of interest i put the offending battery on the voltimeter.....and guess what 5.85v oh well i wll keep it in my box as a spare.

I finished preping the unit and left it stored over night in the garage (as i always do) it was cold later that night about -4c.

Anyway next day (sunday) kitted up ready to dive, switched on the unit and calibrated up. All went as per normal, all until after about 30sec's of holding calibration the cells went haywire. Cell errors, readings were droping to 0.14 then back up to 0.70 as the soliniod fired then back down then up etc etc.

very odd, as there is no gas flow through the unit as it was not being breathed. So i switch it off and decided to calibrate again (must calibrate flashed on when i got to calibrate YES / NO selection).....guess what same thing again cells going dolaly and errors all over the shop.

well 3rd time lucky it calibrates up again perfectly, but this time holds calibration and the cells all read a nice solid 0.98 for about 10mins or so.

Pre breath goes as normal and the cells are reading correctly and moving up and down as expected. all cells reached well above SP at 6m, I dive to 53m for 61mins. All worked perfect no problems in water temp was around 5c.

Was the strange no B1 on saterday connected to the playing up elecs on sunday?? or was it the fact that it was a cold night on saterday and the cells needed sometime to adjust to the temp change?? in between dives my head of my CCR is always kept in the house, its just when its preped to go diving SWMBO says it has to stay in the garage.

I personly think it was the cold causing the problem with the cells. Either way it's all witch craft with these battery and cell things

To test the battery place an 18 ohms resistor (or as close to 18 ohms) across the battery (it will get hot!!!) and check the voltage. The voltage should drop under this load to about 4.8 volts and go back to its normal voltage after removing the load. This test should exclude a problem with the battery.

I'm not familiar with the vision but agree that to test batteries you Really need to check their voltage under a realistic load, even some nearly exhausted cells show a good voltage under no-load conditions.

As HMC already stated: These kind of battery issues are mostly related to corrosion on the springs in the battery compartement. Check them carefully and remove any corrosion. Contact fluid can improve the connection as well.

P.S. One more test to do to prove that the head is faulty... upon surfacing look carefulyy at the Vision and record the state of the notches. Do not turn off the Vision, but sequentially turn off C2 and the on again and C1 and then on again. If the notches go back to normal (a higher state than one notch), the head is f*****!

Hi HMC,

Maybe I don't understand correctly, but why would the head by screwed? Take a look at Tino's article towards the bottom with the heading:

Is this what you are describing?

Just a FYI...

Upon startup the Vision tests the batteries under load by firing the solenoid the heaviest power consumer. If the voltage drops to low during this test the Vision will let you know. If only one battery you can still select dive now, if both batteries you dont get the option to dive.

Hey HMC and thanks for the detailed response. That was informative.
