I didn't buy these so I could throw them away after 2 or 3 uses. The batteries seem to work OK, but I've had a 15% failure rate after only 3 charging cycles. They advertise up to 1000 charging cycles. So, I contacted customer support to ask if the 15% failure rate was unusual and they never responded to my e-mail. 3 stars for the batteries, minus 1 for bad customer support. UPDATE: Four more batteries have failed in the past 2 recharging cycles so that's 7 out of 20 batteries that have failed in the first 6-7 charging cycles. That's $43.75 worth of batteries I've had to throw away. UPDTE #2 - Another one failed, so that's 8 out of 20 that have failed within the year or so.

I was in market for a nice D sized rechargeable and got so disappointed by those in target/walmart that marks 2500mAh, looks like all that energizer/duracell did was put a bigger shell outside a AA battery and sell for much more money. I got 4 of these Tenergy cells from a friend, and they are simply AMAZING!

Not only the capacity is so huge, but also I heard they are the new generation low-self-discharge, and after a few months use, I can testify that all these are TRUE!

One bad thing for me is that I do not have a good charger, my old D cell capable charger can only do 500mA, so it took a whole day and night for me to charge them, but I have never had to do the recharge often at all, it lasts so long that I feel like it is battery than those disposable duracells, although I have not done any precise measurement.

I believe my last set of duracell disposable lasted about a month or so in the baby swing set, and the tenergy lasts for well over a month in my impression, coz I only had to charge them twice so far within 4 months.

I know my AA NiMHs will dry out in 2 months even if I do not touch them, so the low self discharge seems really helped.

Combining all the facts - 10Ah huge capacity, low discharge, and rechargeable! I am sure these batteries are the best D cells I've ever used!

Over three years of near-continuous use with no failures. Don't be put off by the generic name; I've been using various sizes of Tenergy batteries for five years without any going bad.

If there is one shortcoming to these batteries--and I should stress that the problem lies not only with these in particular--is that the batteries' sleeves seem destined to fail long before the conductive paste inside them ceases to hold a useful charge.

It seems that everything one buys for a newborn requires D batteries, but most rechargeables we saw were AAs in a D shell, giving very short charge life. Not these high capacity batteries. These were certainly not cheap, but we can go weeks without replacing batteries, even in the swing, which our son spent a few weeks sleeping in overnight due to his reflux.

We have been very happy with these and would highly recommend them.

I have had these batteries for about a year and use them exclusively in a LED 3D Maglite. They last quite a while and I only charge them every 6 to 8 weeks-I don't use the flashlight that much maybe about 15-25 minutes daily on average.
I charge them with a Tenergy V-9688 Super Universal Charger which charges each battery individually and seams to work fairly good.
They have one significant problem however. From being pushed together by the reasonably strong spring in the maglite their negative flat ends have been indented where the positive terminals or the spring contacts them.
They just keep getting worse. If you compare them to the USA made Duracell Alkaline D batteries, for example, this area is reinforced to prevent bending. If Tenergy just reinforced this area or thickened the tail end I would give these batteries 5 stars.
They are Made In China, so I shouldn't have expected high quality construction anyway.

I would not recommend these batteries if you have a device with a strong spring or will have them in a row pushing on each other.

I guess I'll be one of the dissenting ones from all the good ratings these batteries have gotten. I bought these batteries for the very expensive price they charge along with the Tenergy T9688 charger. After only a couple of charges, 3 of these D cells have gone bad!!! The charger explicitly says "Bad" when I put them in to charge. Huge waste of money will be looking for better cells from another manufacturer.

I bought the package of 8 and one battery was defective. Amazon stated that for a refund, I had to go through the saler. I can not retun one battery, you have to return all batteries.

I order a total of 10 D batteries, 5 of which turned out to be dead. No help from customer support. I'm going to avoid buying anything else from Tenergy as I've had trouble with their battery chargers as well. Very disappointing experience.
