Scubapro Galileo Luna Or Sol Transmitter Battery

    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: th_20160319_1335500_zpss1yqd1wx.jpg

    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.

    I am confused, how long do the new batteries on a new Galileo or Lun computer (and transmitter) should last now?

    Well, scubapro sales people will tell you "years". That seems to be the case for the computer's battery. However after roughly 20 dives, I start getting "T1 Battery Low" warning messages. I had my scubapro dealer ship it off to scubapro and the result of the analysis was that scubapro could find nothing wrong with the computer or transmitter. So, about every 20ish dives, I start getting intermittent battery low warnings and then replace the battery.

    The computer did come back from scubapro with some test dives logged, presumably from some kind of test chamber as the profiles were too "perfect". I assume that means it really was shipped off and tested.

    If you aren't getting warning messages then I wouldn't worry about it. I get the warnings a good 5 or 10 dives before I start getting intermittent transmitter signal loss.

    All of that is resolved with a fresh transmitter battery.

    Thanks for the tip about the new battery. I bought one of the old ones off leisure pro last year.

    I believe the different transmitter models can be identified by the shape.

    BTW, 20 dives is way too few for a battery change. Mine lasted a good 2 years and at least 50 dives. Are you leaving it on a reg pressurized for long periods of time or something? Even then, I believe it shuts off after a period of no pressure change. Would need to check the manual to be sure.

    Nope, I don't leave my regs on a tank at all. I clean 'em and hang 'em on a rack. I can confirm that they do turn off when left on a pressurized tank. When I do boat dives, my procedure is hook everything up and turn gas fully on asap. The transmitter will be sleeping a few minutes later, and I have to wake it up in order to re-check my gas level before splashing.

    That's strange, I've had two transmitters for six years and hundreds of dives and I've only replaced the batteries once.

    How's the new battery working out?

    Any issues with the higher voltage?

    No problems so far. I've only got 6 dives with the new battery (roughly 6 hours).

    Hey there. Thank you for the tip with the alternate battery type. Here in Germany the 2/3 AA Cell from Varta is more common available. I just (must) ordered a new one from a seller in Berlin for 7 €. Perhaps another tip from me: Please be careful with the polarity of the battery during replacement. This is the only cell I know where the knob side is minus and the bottom plus. I replaced mine before I travel to egypt last month and do it wrong. It was complety discharged and I have to replace it again. But I'm a lucky one: I have always backup batteries for computer and transmitter with me.

    I get the batteries for my Galileo Sol at Batteries Plus. Same battery and half the price
