I have had three After market EN-EL3e batteries go bad in a short period of time. One just was bad out of the box the guy sent another it was OK but still didn't hold a charge like the Nikon brand.
For the price of two knock offs buy a Nikon. I picked a used one up at a pawn shop for $4.00 and it is a solid performer, i always ask if they have loose batteries in a box behind the counter.
I have been hitting this huge busy pawn shop once a month or so it has been a gold mine for photo equipment, last was a like mint Nikon Ai-s 105 f2.8 Micro with hood for $50.00.
