I guess I am alittle slow on the uptake, but I had my TC Frogman in the drawer for a long period of time. Now it does not display the time, it flashes a small message "recharge".

I left it out on the counter under a bright light for 3 hours, but nothing yet.

Do I need sunlight?

Thanks,

Tim

Now I'm starting to hate solar watches, it's been raining and no sun for the past several days!
you don't need necesarrily bright sunlight, even if its cloudy the light is still plenty bright, but of course it will longer to charge the watch. this is particulary the case with a frogman or any other model that uses the ML2016 battery.
but once fully charged you don't have to worry about a few rainy days, weeks, month even.


regards, holger

Yeah, sorry to tell you man, but your Frogman is ruined. Go ahead and box it up and send it on over to me and I'll take that junk off your hands. :-!

my recharging system consist of a 1W/3W LED flashlight (rechargeable NiMH AA for guilt-free lumen), a piece of thick white paper and a rubber band

(1) fold a paper cone and use the rubber band secure it on the business (LED) end of the flashlight
(2) place the open end of the paper code close to the dial of the tough solar G-Shock/Casio
(3) power up the flashlight and adjust the distant and diameter of the "device" so that most light are directed on the solar panel of the G-Shock/Casio
(4) go watch TV or place video games for the rest of the night

recharge and repeat as necessary :)

or simply wear the watch out in the sun for a day and have some fun ;-)

hmmm... i tried to charge a g-shock previously using my led light (those 5 mm led type). didn't work after half an hour and i had to resort to my table lamp..o|

maybe the 5 mm led is too puny? :think: ;-)

I know this sounds stupid, but is it possible to send my solar Frogman to Casio Center and request them to do a conversion to normal battery usage? I think the solar panel can be "deactivated" as not to fry the normal battery. I'm really getting tired of putting out my froggie for a suntan.:roll:

I don't see why not, but I guess it depends on how helpful they want to be. Keep us posted if you decide to go down this route.

Of course I would like to, the solar charging is becoming a hassle, but the problem is whether they have the know-how to do it without damaging the watch.

I've got to ressurect this thread, as I prefer to do so instead of starting a new one :).

I've got two "Black Helios" frogmen now (Yay! :)).

One is functional, the other just has an empty battery icon and is flashing "Charge." As I understand it, this particular one is on Charge Level 4. Does anybody have any experience with how long (approx) it takes to get it up to CL2 or CL3, without using sunlight? The reason for no sunlight: I'm in Northeast Ohio, and the weather is cloudy this time of season. So far, I've had it under a trio of lights running simultaneiously: a 35W fluorescent, a 75W incandescent, and a 100W halogen. It was under this combination for about 2 hours last night. Today, I brought it to work, and it's been under a 45-50W halogen for about 1 hr. Still...no change in the charging status.

So at what point do you either try a new battery, or send in to Casio?

That's too much! I left 2 hour under direct sunlight; after that the LCD got all black and too hot.

Manual says 5 minutes under direct sunlight will full charge the watch.
I've copied this from my other post to save time.

The total charge time for G-Shocks is about 18 - 50 hours of bright, direct sunshine to reach a full charge. 5 - 6 minutes of bright sunshine a day is enough to maintain the charge. A full charge lasts from 5 to 11 months of 'normal' use. It varies from module to module.

Hi Topher,

I use a similar lamp as emergency charger too. It can take days before the battery is charged. An hour is nothing, specially if the battery was totally dead. Leave it under the lamp in a seperate room for about 24h (not too close to the lamp of course).

Cheers,

Sjors

Thanks, I had done a search, and must have missed the links. I had a feeling that the battery was so empty that it was going to take awhile. I didn't realize that 5k of lux from the overcast weather could take more than 20 days at 8hrs per day! :-s

Well...at least one of them works. These are my first Frogmen, and I bought them as a pair hoping that the one just needed a really long recharge. But even after all the reading, I didn't think it would be that long.

:-!

Sjors, thanks for the advice. After reading that it could take 20 days or more of overcast sunlight, I think I'll just leave it in a window sill for a couple of weeks. Luckily, the 1st one has enough battery to function.

After all the reading about Frogmen, I took the plunge on the pair. I must say that once I put one on, it is quite comfortable. They wear much smaller for me than I expected.

One concern I do have: the EL on the one I wear is not very bright at all. Have you notice this on any of your solar Frogmen Sjors? Could it just be part of the battery needing a full charge?

Thanks guys for the help!
