Batteries :

• NiCd - Nickel Cadmium - These are rechargeable batteries that offer the most affordable pricing, but on the other hand they require frequent charging and are not environmentally friendly.
• NiMh - Nickel Metal Hydride - These rechargeable batteries are more environmentally friendly, the cadmium counterparts holding charge at least 30% longer.
• Li-Ion - Lithium Ion - These rechargeable cell phone batteries are currentyl the most common o the market and a bit smaller, they offer a longer life and dont experience 'memory effect' but on the other hand, are also more expensive than NiCd or NiMh batteries,
• Li-Poly - Lithium Polymer - These batteries are the newest and the lightest available. Like Li-Ion batteries they hold a charge significantly longer than batteries with older technology.
