This battery is immediately apparent that this is lighter than the Sony original - the replica brings 21g on the scale, the original 27g.
Here you guessed already that the parcel total "less battery" contains. Since the housing and the protection circuit have a share of the weight, I guess that the energy store is likely to be lower about 1/3.
Positives: the replica battery provides remaining time display, which is offered at Sony with the expensive accessory battery.
Overall, the battery life is not great, the already rather large self-discharge of the original battery inserted intensified with the reproduction part.
But I would still buy the battery and a friend, but it serves as a reserve on trips and events - it extends the term of all times, also costs the original eight times!
