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