It is physically larger (thicker) than to original 4600mAh, SD supplied battery pack so sticks out the rear of the recorder approximately 3/4 inch. That is not a problem unless you need to rest the recorder in a vertical position (standing-up on its back panel). It charges fine with the SD external power supply or with an external Sony-type charger.
Addendum December 11, 2012: The first battery I purchased (in October) is still working well, so I purchased (2) more in December. They are the same quality construction and have good contacts. They fit my recorder perfectly and have the same run time as my first purchase.
When received these batteries were charged to about 7 volts. About 3 hours on a 2 amp charger brought them up to a full charge which is appropriate for a 6600 mAh battery.
These 6600mAh batteries weigh ~295g and FWIW, I have a 6200mAh, labelled cell origin Japan that weighs 225g.
Mine came poorly packed, wrapped in cheap bubble wrap and a thin box, then stuck in a plastic mailer bag. Not impressed, because mine arrived with dents in box and stress dents on the battery corners. -Probably- won't affect performance. I hope.
There are higher capacity batteries out there and they should cost a little more, but they should also weigh a little more. Since shipping for these things is always per piece, I recommend you buy just one and then checking quality before committing to multiple pieces.
*EDIT* additional note: the contacts on my battery had a bit of plastic overlapping one side. Depending on charger configuration, this may interfere with proper charging. Beware!
That said, these batteries appear to be high quality. I haven't used them for extended periods of time yet, but they managed to power my external monitor for my DSLR camera just fine. They took about 3 hours to charge, which is consistent with this battery capacity. There's no remaining charge indicator light on the reverse side, but you get what you pay for.
All in all, I am satisfied with this purchase, but these batteries are no-name brand batteries, NOT Neewer brand.
