Pros: Considerably low price for D type battery compare to branded batteries such as GP.
No other Cons for this product !!!

Cons: Poor build quality: I’ve bought 2 packs of these batteries & 3 out of 4 batteries deformed after first charge resulting with rounded bottom side (minus pole)!!!
After second charge one battery starts leaking!!!
I have not measured the capacity of the batteries however it doesn't feel like they are truly 7000mAh batteries: I've used it on baby swing and it barely last one month of very little usage.
Unknown manufacture: there are no manufactures details specify on the batteries.

Other Thoughts: After using those batteries for a while I can definitely state that this is very disappointed product that does not worth the money.
On a second thought it would be much better to buy good AA batteries such as Soshine 2500 or 2700 mAh together with AA to D type adaptor rather then using D type rechargeable ones since they are much chipper ,easy to get & you can use them later on with products that use AA batteries.

Bottomline: This product is not reccomended !
