Title: Delkin Brand Replacement for ENEL-4/ENEL-4a
Review: Would not recommend. Received one with D2X purchased in 2009. Bought 2 new from Amazon merchant in April 2010. The one that came with the D2X failed to charge in about 9 months. Of the 2 new batteries, charged initial charge without a problem on Nikon MH-21 charger when received. Performed fine in camera and took out to recharge when depleted. Would not charge again on the Nikon MH-21 charger. Purchased after market charger just in case it may have been due to Nikon charger circutry check for Nikon chip in battery. Still would not charge on after market charger either. Would recommend paying the additional money for Nikon OEM battery instead to avoid this problem.Additional info: Delkin brand battery was not recognized on the D300 add on grip MBD10. Found this out when I bought the two new for use in the grip.
