How long does it take the solar panel to fully charge the battery?

A good 100 watt solar panel properly aligned to the sun in very bright sunshine will provide about 5 to 6 amps of charge into a 12 volt battery. A commonly used solar storage battery has a capacity of approximately 100 ampere hours (about the capacity of a fairly large "marine" style battery). This battery would require about 12-15 hours of GOOD sunshine to recover from being HALF discharged. This truth is almost always what's left out of the sales pitches for these "plug and play" solar generator systems. Yes, they may have an output of 1000 watts "continuous power"...but the reality is that the storage battery providing that 1000 watts will only last an hour or so. The math is simple. Don't be fooled by vague specifications. ASK QUESTIONS OF THESE SELLERS!!!

I get only about 12-17% charge to my phone per each charge of this solar device. The solar device takes about 20 hours to charge in the sun

About an hour or two. Sometimes it seemed longer to make sure you get a full charge.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

Yes, about 15 minutes of continuous run time per full charge, I think it takes about 3 hours to fully charge. It is really fun during operation, for a battery-powered R/C.

I don't know about solar panels, I've run mine on a 12v deep cycle battery for about 28 hrs, and it was working fine.

Not by more than a few minutes. Would take three or four full days of sun to charge your battery, and thats when your not using it.

Hello, it will take 2-3 hours to fully charge the battery for the keyboard, and about 36 hours continual working time after full charge.

"Effectively" can/will vary greatly from person to person, I would estimate (based off of other charts/graphs/pics) from other solar panels that it would take between 7 and 9 hours to fully charge a 10" (or so) tablet.

It can take between one and a half to two hours to charge the battery if charged when about 15% of the charge remains. I usually do not let mine completely run out but based on the time it takes for 85% of the battery to charge, I would estimate two hours and twenty minutes to two and a half hours for a full charge.

When the solar battery is fully charged it last all night long. It will go from approx. 6PM to 7AM in the morning when fully charged.

The light will blink green until the battery is fully charged, then it will glow solid green to indicate it is ready to use. It typically takes 1 - 2 hours to charge completely.

It seems to take a while (hours) but I haven't timed it. My routine is to charge the battery after use or the night before I plan to use the hedger.

The light turns green when is done, while it is red when charging. To fully charge the two batteries that comes with the pack you will need approximately 4 to 5 hours. If you add the battery that comes with your camera you will need about 6 to 7 hours to charge all of them but you will have your machine shooting for thousands of photos .

Mine was nearly fully charged when I received it. I have not run the battery completely dead during any single use yet, so I can't be certain. I would guess it should fully charge within an hour.

If the Leaf computer estimates a low range such as 15km remaining then it takes about 4 to 5 hours to bring it back to 100% charge. We charge at night when the electricity is cheaper. We often charge to 80% since this will extend the life of the battery.Good luck and consider the AeroVironment EV charger for purchase...it is a very good unit!CheersBill

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.
