Be carreful,
Sony use classical batteries, with the charger. To charge in 15 minute there i a high currant (in Ah) coming in. If you don't have specific batteries, the classical one may have some problems (heat) or durability.
Sony claims that 15 minute and the charger commes with 2500 mAh batteries.
But sone times the charger stop to charge after 15 minute because of a switch timer. but does mean that batteries are fully charged. For intance GP announced a 15 charger with AA 2500 mAh batteries. but have a look on the User Amnual and you will see, that after 15 minute the 2500 mAh batteries will be charged at 65% of their capacity, so this is the equivalent of 1875 mAh fully charged batteries!!!. So the claim is wrong, but you paid for it. Imagine that your Digicam says 8 mega PXL, but after reading carrefully the user manual you realize that in fact it is 4 mega PXL!!! but this the reallity with some chargers. But who is abble to measure the capacity of the batteries after charging?
Have a look on the back side of the pack. seems that Sony use the same technology as GP, so not real 15 minute.
The only real 15 minute charger that i know is the Varta, so far (i bought it in Europe, but i saw it in several shops in Singapore). Ok they come with 2000 mAh batteries but they are fully charged. OK batteries are specific to accept high current, but charger charges classical NiMh batteries in 1 hour (up to 2500mAh).
Hope this will help.
