Best Way to Charge a Tough Solar G Without Frying It?

So I finally acquired my first G-Shock. A Frogman, (GW-200MS-1) and naturally, since it's a watch that was released in 2009, it's gonna need a bit of a charge. I've got a few questions that some of you gurus out there might know.

What is the best way to charge it without frying it? It obviously wasnt cheap, and I'll kill myself if I ruin it by leavin it in the light...

If I just wear it around all the time, outside, or say, in a well-lit room, will that keep it charged?

And how long will this solar battery last before it kicks it and I'll have to buy a new battery?

Where should I go to replace the battery if need be? (I've heard some bad stories about local repair shops or jewelers)

I know I've got tons of questions, but I'm new to the whole solar battery thing lol.

Thanks

You wont fry it by leaving it in direct sunlight but if you don't want to do that put it in a glass of cold water before exposing it to the sunlight.
A solar battery will last an eternity I have nearly 40 solar g shocks and only ever had to replace 1 battery in the last 10 years they are quite expensive to buy though compared to non-solar batteries.

It will get very hot ... could burn your wrist if you strapped it on straight from charging without letting it cool down first.

I've read elsewhere in the forum that some place the watch in a shallow pan of water to keep the case cooler.

Others can tell you whether or not the heat can otherwise affect the components.
Also read it somewhere if it gets too hot, the screen will go blank for a while.

In my experience with my PRG-110 which I have had for over 4 years now, I think I had it go down to M once, when I left it in my survival box in my summerhouse in spain for like 5 months, since then it's been on H, by simply wearing it with a T-shirt, i.e. no sleeves. I rarely leave it in the sun specifically to charge. I do however put it next to a window so it can sync overnight (usually at 2:02 or 3:02 am), and skylight (not necessarily sun) hits it in the morning for a couple of hours. I never put it close to incandescents. If I would be in undercharge, I guess I would zap it with my 20,000 Lumen LED flashlight lol.

Best Way to Charge a Tough Solar G Without Frying It?

Well, to answer that question, first you need to know the best ways to Fry your watch for sure. ;-) Then you try to avoid those. I can think of two.

One, use magnifying glass to concentration the power of the Sun onto your watch. While a very effective survival skill, it will for sure, fry your watch. After all what the solar panel needs is light, not heat.


Two, use a solar cooker to "energize" your watch. Well, it's the same principle as the magnifying glass trick, only magnitudes stronger in solar power! It will charge your watch into a crisp charcoal, as well as cooking your chicken.

I can't even believe this thread title. Really??? Is it that difficult?? :roll:

The sun is the best method, I think most of us know that. High-powered flashlights do work too.

First choice in recharging Solar G's?
Southwest Window sill. I've had tons of Solar and MB6's I've charged using the Texas Ole Sol.
Never fried one yet!!!! Not only Casios but Seiko and Citizen Solars too. I've even forgotten to
remove em and still no damage!
No mo battery powered watches for me!!!! I own 8 Casios. All but 2 are Solar G's.

So .. i am assuming that a G Shockhas been fried at some point.

Perhaps by someone leaving in the Mojave Desert where the UV index was high and not checking back.

How much heat does it require to fry a G Shock?

G placed on A car dashboard in the Sun will cook plastic parts.

As always, RTFM, where proper G treatment is documented

just ordered a casio 5610, get it tomorrow....

Because my protrek 6600 isnt respondimg to any radio signals, well it got l3 for a seccond, no fix, Err

and I have fried it in the window sill for 6 hrs, battery still at M


Thus 5160 to compare and wearing while one of them are at low battery,
I really hope I can get this protrek charged for the weekend :)

6 hours isn't enough sunlight. A few days of straight sunlight would be better for the battery and charge indicator.
