I'd been getting my Galileo Luna transmitter batteries from my scubapro dealer because it was an oddball battery that I couldn't readily find anywhere else (including internet). Most recently when I went for batteries, they used a different battery than they had been using. They assured me the batteries came from scubapro, and the transmitter does function.
This battery shipped in my Luna's transmitter:
Varta CR2/3 AA 3V 1.35ah
This battery is the new model replacement:
Expocell ER14335 3.6v 1.65ah 150522
The transmitter doesn't seem to have a problem with the slightly increased voltage, and as you can see by the ah rating, the new battery has 22% greater capacity.
What's more, the ER14335 battery is available all over the internet much less money. I had been paying $25 a battery at the scubapro dealer. Amazon has 4 packs of the ER14335 for $23! I found individuals for around $12 without much searching, too.
Hopefully this helps someone else who needs a transmitter battery. If you're getting "T1 Battery Low" chances are you need a battery. That message does not indicate signal loss, there is a completely seperate error message when the galileo loses signal. "T1 Battery Low" means the transmitter sent battery capacity information (probably voltage) to the computer to indicate low battery.
Here's a photo of the battery installed by my scubapro dealer:
As far as actually replacing the battery.
1. Remove transmitter from your first stage
2. Remove the three phillips head screws from the transmitter
3. Pull the transmitter apart with your fingers
4. Pull the old battery out of the battery holder
5. put in the new battery and put everything back together
easy as pie.
There's an O-ring involved, so keep an eye on that and replace if it starts to get flat or brittle like any o-ring.
I hope this helps someone else. It's been a big annoyance with my Galileo due to how frequent this battery must be replaced. The actual computer battery lasts much longer. I think I've replaced it once in 3 or 4 years, so it's much less painful paying the scubapro dealer's price.
Caveat: I understand there is an "older generation" of galileo transmitters that uses a completely different shaped battery. I don't have information on what year they switched or how to identify which one you've got - except to open your transmitter and see what's in there.
Yes, I know, a thread about changing a battery seems kind of silly... If you've tried to find and replace that varta battery you'll know my pain and perhaps appreciate this information.
