Hello,

I have a G757 4030 and I replaced the battery shortly after I had received it. I do not remember what the battery was when I had purchased my G757 off of EBAY. It is in pristine condition.
I had replaced the battery with a (1.55) Volt and the G757 worked perfectly for a little more than a month. Then few days ago, the main screen went flashing as a low battery sign and then stopped. Is this normal for batteries and this watch, I know the history of how much “juice” she likes.

Last time I searched for a cell I had a hard time. What is the battery number for this watch, and what do you the pros recommend the most?

I would be most appreciated, Thank you!

The G757 module is a hungry beast, but shouldnt eat the battery that fast. There is obviously something wrong with the board draining the battery that fast. First try a high qualty battery as the hold the charge of 1.5 for longer. The cheaper batteries go below 1.5v as the lose their power. This sets off the flashing ‘battery low’ on the board. This may or may not work. Other than that you can have the board cleaned to remove any residue of age that may be causing the short to drain the battery so quickly. Lastly you’ll have to either live with it or try and source a new module.

Off the top of my head I cant remember the battery, you can just down the tech guide from the site and it will show you there.

Renata a good battery.

regards

Adam
