i use an unbranded one from ebay, but it lasts just as good as the Nikon and i seem to get the correct battery info from it.
just says, "Battery pack EN-EL3E 7.4V 1800mAh 13.3Wh".
i never put it directly in the camera, only the MB-D10
Is there a reason why you don't use rechargeable AA's. 8 Duracell 2450ma batteries are £9.00.
can you get a 3rd party EL4A? and have you factored in the specific charger for it? and the new door for it?
I looked at it earlier in the year and went down the duracell route which gives me the same outcome at a fraction of the price.
thanks FITP
have looked further in to it and it appears you can get the same outcome (i.e. frame rate etc).
