Use a 12 volt largest marine battery you can get. Keep it charged up and should last all day while out

The correct battery is the 18650. You could also use two CR-123 batteries instead. Either will do the job.

The batteries needed are two D cells, preferably alkaline. A set of batteries should give you 20-25 hours of running time.

Regular AAA batteries do the trick fine. Very compact and bright. Recommended.

Agreed on AA batteries. I do a bit of international photography and can always find AA batteries. It's impossible to find specialized batteries in most of Africa and Latain America, and a charging unit for a specialized battery is just more gear to lug around, with the risk of loss.

Any battery works. But it depends on wattage of pannels some larger pannels are built for 24volt instead of 12volt. Check the specification. It is better to use a deep cycle type. You can have multiple ones, but have an even number of them.

The battery should have been included. If you contact Amazon, they will make it right.

Batteries, but good luck. The quality of the screws locking the battery compartment is so poor that three of us adults could not get them out. I would definitely not purchase this.

Batteries need to be fully charged, depending on sun, it could take a couple of days.

I'm not sure what you're looking for. A battery for the transmitter or helicopter/plane?

A 12volt car battery will work. But most people including me, use a deep cycle marine battery. It lasts longer per charge.

Required one Lithium Metal battery. Regarding duration it's depending how you use.

Mine came with a battery already installed. I have not opened the unit to determine the type.

My understanding is that it is the type of battery. The SL requires the slide-type battery.

It takes a 12V Alkaline battery Type27A (round, about half the length of a AAA)
