It can be used with a solar battery charger.
For Alkaline batteries i recommend putting in great sunlight or buying an electrical battery charger.
i think there is a way back in my country my grandfather used to put the batteries out in sunlight and it worked again i think you have to leave it out for almost 4 hours
A charge controller is a regulator that you used to keep batteries from overcharging as well as undercharging. You need to keep batteries that are in storage charged so a charge controller will help to keep them at the right charge level.

the sunlight hits the batteries and powers them :)
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.
Each has solar pannels that will charge solar batteries until sand builds up on them and stops the sunlight from getting to the cells...Ending our brave little robots' life.
No, sunlight carries no electrical charge.
A battery charger is used specifically for rechargeable batteries. It cannot be used with regular batteries. It's a base that's plugged into an electrical outlet. You place the batteries on the base to charge them to be used multiple times.
A set of NiMH AAA batteries can last roughly a month on a full charge if they are not being used at all and are simply allowed to sit around. In devices such as cameras and small pda's where rechargeable batteries are best used, the batteries can last nearly as long as normal alkaline batteries on a full charge. Exact times depend on the capacities of the NiMH batteries. A charge lasts long enough for a camera to be used normally for several days and hundreds of shots. As long as the NiMH batteries are not allowed to be idle and self-discharge, the life of a single charge is almost as long as a full alkaline battery. The life of the battery itself can easily be several years. NiMH batteries don't need much maintaining and can last for hundreds of charge cycles.
You could put the batteries in a very hot and sunny place where the sunlight could charge it.
By using solar energy to charge the batteries
