Shearwater AI Tansmitter Battery Change

[lowflyer]

Has anyone decided when or how often to change the battery in the Shearwater transmitter? As far as I can tell, there is no indication on the computer with regard to the charge remaining in the transmitter battery. It will indicate when it gets "low".

Apparently, the battery is good for 300 hrs. But I was thinking maybe I should change it when I change the computer battery. What are people doing?

I wait until it stops working

My transmitter is also read by my OC1, which does tell me if the battery is OK.

When it tells me it is "low" is when I change it.

Hopefully not during a dive or other inopportune time

I have an SPG. Not a big deal.

My DG03 reads it. It's "rated" at 300 hrs so my plan is to change it when it has about 200 hrs. CR2 batteries are CHEAP! Since I am averaging about 150 hrs per year doing vacation diving, I'll probably change it every January 31st.

I figure I've wasted money on AI if I'm going to have an SPG on my recreational dives. Just my opinion, but that's why I want to make sure my transmitter battery is up to snuff.

I dive a 7 1/2 year old Oceanic VT3. I generally change the transmitter battery whenever I change the computer battery. The computer battery status is displayed on the main surface screen. I change it soon after the low battery icon is displayed. Both batteries are said to be good for 1 year/300 dives. I've generally been getting about 200 dives per battery on the computer for the last several years. My transmitter battery has never gone out with this strategy. However, I can also check the transmitter battery status whenever I want to, and do occasionally. Does Shearwater not have this capability?

Shearwater Perdix does not check the transmitter battery. Again, as cheap as CR2 batteries are change it once a month or before every dive trip.
Just my $.02
