No set answer to that. It depends on the capacity of the battery, the size and efficiency of the solar panel and the intensity of the sunlight.
A few variables are involved like, does the solar panel have a charge controller, what condition the battery is before you start and how much sun is the solar panel receiving.
That depends on the amp-hour capacity of the battery.
That depends on a number of factors, including the specific design of the lights, the age and condition of the rechargeable batteries, and the amount of sunlight reaching the location of the solar panel (partial shade, cloud cover, season, etc.). However, most such devices are designed to achieve a full charge in 4 to 8 hours of direct sunlight.
A very long time. I would guess 48 hours of sunlight at the very least. Even that may not be enough to fully charge the battery. It really depends on how much amperage the solar panel is putting out.

The time it takes to charge a 12-volt battery with a 13-watt solar panel will depend on various factors such as the battery's capacity, its current state of charge, weather conditions, and efficiency of the charging system. On average, it may take around 8-10 hours of good sunlight to fully charge a depleted 12-volt battery with a 13-watt solar panel.
Most likely not. In order to charge the battery to its nominal rated 4.8 volts, youreally need a source capable of more than 4.8 volts open-circuit.You need to take the solar panel and a voltmeter, and measure the output voltageof the solar panel with no load connected to it. If it's more than 4.8 volts, then itwill charge your battery.But . . .That's not saying anything about how long it will take. 0.4 watt is not an awful lotof power, and your solar panel will not even deliver that much before its outputvoltage sags to 4.8 . So I would think that this solar panel will not be an acceptablecharger for that battery.
if they are rechargeble batteries then yes you can but they wont stay charged for that long
To estimate how long a 12V 20W solar panel will charge a 200Ah battery, you first need to consider the panel's output. A 20W panel at peak sunlight (about 5 hours of effective sunlight per day) produces roughly 100Wh daily (20W x 5h). To fully charge a 200Ah battery at 12V, you need 2400Wh (200Ah x 12V). Therefore, it would take around 24 days of optimal sunlight to fully charge the battery, assuming no energy loss and ideal conditions.
Olympus camera batteries last on average the same as other battery brands. To extend the charge life of your camera battery be sure to not use the LCD panel since it drains the battery.
normally 8 hours
The batteries are over the counter watch batteries and they last twice as long as the battery put into the walker
