Battery switching problem!

diverrob · 29th October 2006, 23:47

I am looking for any feed back anyone may have on the dive I have discribed below

The dive in question was a no decompression dive to 70’. It started out well and at around minute 12 of the dive I got a low battery warning. At the same time I looked at the hand set and saw nothing but lines and black on the screen. The screen would come in and out as I tried to manually switch to CP2 but every time I auctioned a button the screen would go blank (because the back light would use more of the voltage I assume??) after a few attempts to manually switch to CP2 the hand set went completely blank and I was left with only the HUD. I ascended to 20’ adding O2 manually using the HUD to keep the PO2 near the set point and when I got a steady red light on the HUD I went OC. At this point the hand set came back on and I was able to manually switch to CP2 and all was good except the temp stick was not registering so I went back on the loop. Once CP2 was promoted to master I was able to turn on CP1 which stayed as the slave for the duration of the dive. When you look at the file it shows that the dive was only 13 minutes long and the rest of the dive was not recorded even though I was in the water for another 12 min longer than the file shows. My question is why did the system not automatically switch to battery 2 when a low battery was indicated and how can I prevent this from reoccurring?

Hi Rob,

what version of the software are you running? And please report this to APD. This is a major issue.

I have the latest version of software and I have sent a email to SDS

Maybe not running the recommended manufacturers battery type might have caused this? With the vision the batteries should switch automatically and this cannot be done manually as I am aware.

I had a problem with mine not switching batteries...the solenoid didnt fire and I had to inject manually..my problems was nowhere near as serious as that but still caused me to abort the dive.

The log showed the solenoid didnt fire but there was no explanation as to why it didnt swap batteries..even though the display showed both batteries at 3 bars.

Since updating to the new software it hasnt happened again...(touch wood

Funny that, the exact same thing happened to my buddy diving an Evo this afternoon, that's why I'm on RBW now, looking for similar incidents.

He's also got the lastest software loaded on his, Trimx V30 02, mines still the original V30.0 We had completed a 37meter dive and were ascending the shot for a bit of deco when at around 15 meters, he got the low battery warning on B1. He expected B2 to be promoted on accepting the alarm but this did not happen. What happened next was that he got all the alarms coming up, lost temp stick display then the hand set started flashing on and off in rapid succession. Needless to say, this was alarming!

He ended up doing the rest of his deco on open circuit bailout as we weren't really sure what was going on with the unit. When we got to the boat, we had great difficulty turning the unit off as the buttons were not responding too.

AP were called this afternoon after the dive and we are waiting on a reply.

Could this be a cold water issue with battery levels dropping faster than expected? The software came out in the spring/summer. Now it is winter and suddenly we have battery problems.
Or are most inspo divers only now getting to the EOL of their fist battery?

It's hard for me to believe that this is a temp issue. the head, where the batteries are is kept quite warm by the breath and heat of the sorb. I could see cold temperatures being an issue at the beginning of the dive but not at the end where the unit is fully warmed up...IMHO.

You are right in saying that you can not switch batteries but when I finally switched to C2, it also engaged B2 and then B2 stayed primary for the rest of the dive.

It's still a worry, when my mates battery warning came up, the screen went crazy and would not respond to button pressing as everything was just flashing on and off.
