Dano,,,I have your M-680L light for the same reason the original poster said. I never have to worry about recharging because it's stays in my drybag for 6 months until I need it on the boat (even though I dive almost every week). I have a bright pencil light on the tip of my gun that is perfect for under ledges without spooking fish. But on the rare times we are diving in 10ft diameter huge boulders, I need the 680.
It's a great brite light with a push button, battery indicator, and best of all super cheap size 123 disposable batteries. I never leave the batts in the light and carry 3 sets cause they are tiny and take up no room. For those of us that bring a backup light and 'need it to work' when out on a day boat. The M-680L is{was} a workhorse with cheap size 123 batts for a drybag backup light.
Thanks very much for the positive feedback John.
The light you have was a good one, but we have since moved on to what we feel is a better light.
In any regard, this discussion prompted me to break out a few 123 batteries and put them in the newer 970 lumen light. They seem to work and I don't see any obvious difference in light output. The two batteries are more volts than the 18650 rechargeable, but it seemed to work.
I'm going to fire off an Email about this specific question to my factory to see if they can give the thumbs up for the flexibility in batteries. They definitely fit and the light works, but before I recommend that option, I'll need some confirmation.
THANKS guys for bringing this up. If we can deliver even more flexibility with regard to power supply, everybody wins!
