How to Recharge a Solar Powered Watch Battery?

Solar watches are a new product in the market, and many big brands such as Seiko and Casio are in the competition. The solar powered watch battery is long-lasting and durable. It can work for up to 10 years. Besides that, users do not have to worry too much about recharging. 

Recharging a solar battery is very easy. All you need is a source of light. The best part is that it can work under sunlight and artificial lights. A solar watch needs to change batteries every five months, but there are some brands such as Casio and Seiko boost for their long-lasting products.

Some of the models last up to 8 months after a recharge. It is really interesting because now you do not have to change the battery too often. Today I am going to tell you how to charge a solar watch with a few simple steps. 

Please remember that it has a lifecycle, and frequent recharging may die out the batteries. I have divided this topic into two parts: normal recharging and temporary recharging. first, let me tell you about- 

Normal Recharging 

You can find a charge level indicator on the dial. If the indicator shows a red sign or zero, it is time to recharge the battery. You have to follow the below process- 

Place It under a Sunlight 

I would suggest direct sunlight, but you can use artificial lights if you have to charge them at night. You can place it on your balcony, or if you are outside, you can keep your sleeves above the wrist to expose the watch to direct sunlight. It can take up to 24 hours in direct sunlight or 50 hours in artificial lights (sometimes on cloudy days). Yes, it is long, but it can give you a power backup of 8 months to 2 years. 

Place it Under an Incandescent Bulb 

Please note that if you are charging it under artificial light, you have to maintain a distance of around 20 inches from the light. Experts suggest that artificial light is not efficient in recharging the battery. It can take up to five days to get fully charged, depending on the power of LED lights. 

Temporary Recharge 

If you want a temporary solution, you can charge the solar watch under sunlight for an hour, and it starts working. As I have said already, you have to place it in the sunlight for a long time to get fully charged. 

On the other hand, you have to wait at least five hours to get a power backup of 24 hours under artificial light. 

That is why I prefer a fully charged battery under direct sunlight. The solar panel on the watch generates power more efficiently under direct sunlight and saves the power in the battery.  

Besides that, I would also suggest maintaining a battery of 35% to 85% for its durability and efficiency. 

Reset the Time 

If the watch has reached the no charge label, you have to reset the time again. Pull the crown on analog mode and leave the crown out for 30 seconds. Now reset the time. 

Now pull the crown out in digital mode, and the clock will start working. You can turn on the display light to check the hands are moving properly. Press two o’clock buttons (depending on the model, my solar watch has this function) to change the seconds, minutes, and hours on display.
