 We put all the brands to the test, using a pair of identical Mini-Mag AA flashlights, and found our Gaiam Real Goods NiMH rechargeables outlasted the top alkaline battery by almost 30 minutes. Despite the TV ads touting advanced technology, alkaline batteries have not gotten significantly better. But rechargeable NiMH batteries, which have always excelled in terms of environmental impact, have pulled ahead when it comes to performance as well as economic return. A NiMH rechargeable battery delivers 2,200mAh and will do that about 500 times before you throw it away. The best alkalines deliver approximately 1,800 to 2,000 mAh -- then they get tossed. We did the math and found 4,000Ah of power costs 1,425 with throwaway alkalines and only 61 with rechargeable NiMH batteries, including charger and electricity. Our rechargeable battery kits give you everything you need to keep toys and gadgets running, without wasting money and the environment. Our large kit is perfect for households using a wide variety of NiMH, NiCad or Accucell battery sizes. Its charger provides four bays that recharge AAA, AA, C or D cells, plus two bays that recharge 9-volt cells ? doing so faster, and better, than any other charger we've seen. The large kit comes with AC and DC power cords, and can charge off a 10- to 15-watt solar panel with appropriate plug. Large Rechargeable Kit includes: AccuManager 20 Battery Charger, 4 AAAs, 8 AAs, and 4 Cs.
