Hi,
Today, after a long time, I finally had the chance to test my new Retra Pro Max strobes underwater.
Unfortunately, the excitement didn’t last long. Underwater, one of the two strobes only turned on briefly before shutting down with the message: "Please charge the battery." It turned off immediately after that.
I had charged the batteries (relatively new Eneloop Pros) the day before and only took them out of the charger this morning. When I inserted them and did a quick test, everything seemed fine.
Frustrated, I had to end my dive early.
When I placed the batteries back into the charger, it displayed the following values:
1.36V – 066mR
1.35V – 120mR
1.35V – 120mR
1.34V – 015mR
After charging for 30 minutes, the values were:
1.48V – 066mR
1.47V – 120mR
1.48V – 120mR
1.48V – 015mR
The charger added 141mAh – 184mAh, meaning the batteries were far from empty.
Honestly, I’m very disappointed. Even the second Retra Pro Max started showing signs of power loss after just 60 shots.
Is there a solution for this? The Eneloops shouldn’t be defective, right? My Sea&Sea D2 strobes worked perfectly with any battery and never had issues.
I definitely won’t buy the Booster Pack—I'd rather sell the strobes before doing that.
Ah, in case it’s important to mention—the water temperature was only 6°C.
