Great long lasting rechargeable battery. Takes about a year to start benefiting from the cost savings but the're better for the environment starting at day one.

With the price of alkaline batteries it is easy to save some bucks with rechargables and the Tenergy NiMH is a good one. It holds up well for radios and old flashlights. When looking at NiMH batteries, check how many times it can be recharged!

We have used several other brand D cell NiMHs over the years. The other brands have a failure rate of about 33% over the first 2-10 charge cycles. We have yet to loose one Tenergy NiMH D cell after 100+ charge cycles. Great price when you consider how much you can save over its lifetime.

As I still have several D cell flashlights, these come in very handy. I almost hated to fire up the Maglites in the old days. No problem now these do the trick and don't show the voltage sag I used to see on non rechargeables. Well made and time after time they hold a full charge, only time will tell, BUT they will have paid for themselves many, many times over before they start to show there age. Great product.

Great price, awesome battery, they last forever, no complaints! watch out for an update once I get some more \'mileage\' from them.
