Pros: Not a bad product.
Has the big capacity (~280 mAh, but I doubt that it so. It seems to me that capacity ~200 - 240 mAh).
It is executed from firm, white plastic.
Low enough price (I am cheaper did not see).
It is delivered in packing, with the instruction on an underside.

Cons: Long time of gymnastics, approximately 25 hours this results from the fact that the battery has the big capacity - 280 mAh. Batteries with smaller capacity, are charged much faster.

Bottomline: Not a bad product.
Has the big capacity.
It is executed from firm plastic.
Low enough price.

Pros: I look forward for the 9V rechargable. It is difficult to find in store here.
When it arrived, it had 8.71V, I thought 'Great', and ran a capacity test at 100mA constant current drain... It lasted 25 minutes, Mamma Mia....
That was yesterday. After overnight charging with standard charger, it came out 10.71V (strange, they might have put 8pc of Nimh inside). OK, tire meets the road.... it rans for 1hr 33minutes, rating at 155mAh, Depressed...
Upset about Dx selling these overated battery, for every of the 4 of 5 I bought(haven tested the Soshine yet), they overrates by 2 to 3 times, 1/3 to 1/2 of labelled capacity...
Undetered, I went on the internet looking for reputable shops selling reputable brands of battery, here they are:
Energizer 175mAh $9;
GP GP17R8H(9V size, 8.4V Nimh) 170mAH $5 (This is odd might use 6 pieces of skinny Nimh, not sure)
GP 9V size 9.6V 170mAh, $7
GI 9V 100mAh NICD, $1.75 ~ $2.
And then, there are various brand like Titanium, Noma... yes 250, 260mAH, $5 to $6. I feel batter.
The only brand I trust is Energizer for honost rating...

Cons: I understand Chinese companies (selling to locals) are still in the primitive stage in marketting, relying on selling bogus (rated) products at CHEAP prices. Sooner or later, they will learn that they can sell for $7 just the same 9V by increasing their 'ingredients'. Building brands takes time...
I still blame Dx for not stated in the catalog " DX tested this battery to have the capacity of 155mAh". And there is no shame because DX buy what he thinks are value products. YES, they are still less expansive than elsewhere. This is the way DX should dispells many customs' concern of bad products. (I don't Dx listens. Everybody takes times to get smarter, ;P does everyhody?.....)

Other Thoughts: My Canon cameras, sony camcorder, computers.. are all make in China, they never disappoint me. Many years ago when these startd, I simply passed. Now if they aren't made in China, I must have paid too much... What a turnaround.
And yes, it is NOT easy to send capsules into orbits. Chese consumers are still maturing.
For the time being, it depends on customers to do some hardworks to guide a round. I too, benefit from other telling me which SKU are solder paste (fine grains of solder with flux in past form) from Flux which Dx do not distinguish them.

Bottomline: Bottom line: Life is interesting, I never can tell I would go all the troble of custom-designing and build a current drain tester to review for free... all in the midst of busy days... Good night.

Pros: Cheap, good and useful 9 volts battery.
Good built quality.
Nice package.
No marks, damage or leaks.
Close to marked capacity.

Cons: Maybe a better price??????

Other Thoughts: I bought two and both work very well in my digital multimeter. Perfect for electronic laboratory practice.
Think about various charging cycles before to get full capacity.
Close to marked capacity not like other batteries highly overrated.

Bottomline: Good batteries with nice price and good quality. If you need this kind of batteries it's a good choice.
Real capacity near to marked capacity.

Pros: Very good and well work produkt, very cheep, nice, it last tow houers non stop working time, I'm very satisfied, sory for my english hope you understand everything

Cons: I try it whit whired microphone , it work, nice, recharg it and it work perfect, what else can someone sa for a batery, it work esey, for many thing, for toys, and other stuffs

Other Thoughts: i must by now recharg tool, and will have everything new
