NiMH Rechargeable D Batteries, 2-Pack
NiMH Rechargeable D Batteries, 2-Pack
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.
Nickel-Metal Hydride batteries just keep getting better and better. Our batteries excel at hard use and deliver steady voltage with no sag all the way down to 10% of charge. This makes them a better choice for heavy-discharge uses like digital cameras or remote-control toys, where you actually get to use more of the stored energy than any other battery type will deliver. There is no memory effect from short cycling and no toxic content. Because they self-discharge over 3-6 months, these cells aren't a good choice for emergency lights. China.
D batteries (7000mAh). 2-pack.
