These batteries have only 2500 miliamp hours of capacity. Most NiMh rechargeable D batteries have about four times this capacity. Even most nickel-cadmium D batteries have higher capacity than 2500 mah. This battery is simply a sub-c or AA battery enclosed in a plastic shell the size of a D battery. In other words, this battery packs as much power as a AA battery. Stay away from Energizer D batteries. Get another brand such as Powerizer, which has four times the capacity.
We had 8 of these batteries for our daughter's baby swing - it needed 4 at a time, so we would charge the extra set while she used the first set. Regardless of how often we changed them (depending on how much she used the swing, it varied from 3-7 days) we always had a charged set ready. Since she used the swing daily for nearly a year, we would have spent a fortune on regular batteries even if they lasted a day or two longer than these!
I bought these batteries for my daughters baby swing. The batteries last for maybe 6hours on a full charge. I was hoping they would last like normal batteries (15+ hours), but they don't. These rechargeable drain so fast that I had to buy a whole new set just to swap them out while they charge. I wouldn't recommend these batteries.
I have used rechargeable batteries for many years...the NiMH's usually perform quite well. This particular brand and battery size has been very disappointing. Originally used in a light duty hot wire foam cutter it works well. But for anything beyond that light usage, my experience has been that it does not maintain a charge for very long under any other kind of load. Tried to use in a battery operated ornament spinner but it will only last about 1 hour before it needs recharging.
Can't vote thumbs up on this one.
When you pick up this 2 pack you notice how light it is. That's because its really just an AA battery in a D size shell. Read labels before you buy. I wish I did. These only have 2500mh, same as many AA recharge batteries. The "green " theme is just to be PC. They have little interest in selling recharge batteries since it will cut their regular battery sales IMO. Other brands offer 10000mh D size that will last much longer between charges for only a little more cost.
WORKS GOOD IN MY FLASH LIGHT VERY GOOD.
The batteries are economical, environmentally friendly, and on the surface a promising investment; however, they just don't hold up. A standard D cell from this brand will last a week in my daughters swing, its rechargeable counterpart only last for a day and a half at most. IMO that isn't so great.
So far, I've only recharged them once (but it took all night long) I bought a total of 12 batteries for my Mutant wireless indoor/outdoor speakers. The charge is still going after about an hour. I'm going to wait until the batteries die before I charge them again. I bought 2 chargers, because you can only charge 4 batteries at a time and I have 12 batteries.
discharged and REcharged three times; works perfect!
These only offer 1.36 volts!! D size normal battries offer 1.56 volts. These a worn out AFTER they have been charged. I doubt very much if they will work as intented, because once regualr D's get to that level, my unit qui=ts working, and or slows down.

For me, Energizer is the best battery.
Works well. Honestly if you use DD batteries alot (with young kids) then you HAVE to buy a couple of packs of these. Trust me. It'll save you time and money.
I never purchase non-rechargeable batteries anymore! This is a great price for rechargeable batteries.
Haven't had and used these for long however first impression is favorable. Like the fact they are lighter when compared to other similar products and much more reasonable than if purchased at Radio Shack.
I use these batteries for many rechargable hours in flashlights and walky-talky products without failures. I recommend these batteries to anyone who has longterm use for rechargable battery use.
Charge, use... simple as that...
But over time y'all find out ya save money on batteries purchases I used rechargeable before in the past. I had them for over 5 yrs before needing to replace them.
I was happy to finally find rechargeable D batteries for my mag flashlight. They are so much lighter.
Product works great. We were going through batteries at a crazy rate in the baby's swing and now we can just recharge these batteries and keep the swing going.
