Have something that your always needing batteries for? Well I've got a great idea for you! Try rechargeable batteries! I just got some for my digital camera and they're great!! I never run out of a good memory now! They have all kinds of cool stuff for your batteries. They have the green batteries that have been recycled, solar powered charger, and battery testers.
With the rechargeable batteries themselves, they come in all the different kind of battery sizes. You can get any brand you want or green ones as well. With rechargeable batteries, all you do is use them and when they are dead, you just put them in a charger and they charge right up. You never run out of a good battery!
The charger is something different. That's what you put the batteries into to charge. Just like the batteries itself, the charger has all different kinds of them. Different brands and styles. They have chargers that will just charge one battery at a time and they have some that can charge 10 at a time.
The solar battery is usually a solar strip that can charge from the sun. I think that's awesome! So if you have a camera on the beach and you run out of batteries, and having no plug in, you just get this charger out. It charges the batteries right from the sun!
So if you were in the boat I was and needed lots of batteries and knew how expensive they are, I would just get some rechargeable batteries, That way you never run out.
