The Sunbender Build-It-Yourself Solar Battery Charger Kit allows you to construct your own solar powered charger for rechargeable batteries. The kit once constructed can charge two AA batteries at a time.
This build-it-yourself kit comes with all the pieces required for a working battery charger suitable for recharging both NiCd (Nickel Cadmium) and NiMH (Nickel Metal Hydride) rechargeable batteries. The charger will be able to charge the batteries at a rate of 50mAh. This means that for every 5 hours that you leave the charger charging in sunlight, your batteries would gain 250mAh of charge. The charger is designed to take two AA batteries at once. The charger may take a while to charge batteries of a large size from empty, it would be best to then use this to then top up batteries when they are not in use, for instance charging through the day while out camping, to be used in a torch at night.
The Sunbender Build-It-Yourself Solar Battery Charger can be used as an effective educational model to teach children about the benefits of solar power. The construction of the charger kit allows the child to engage with it, helping them to learn. Once made the charger allows you to be able to charge your batteries without the need for mains electricity.
