Nikon Inc. is asking your cooperation in connection with a voluntary recall of certain lot numbers of its Nikon Model EN-EL15 rechargeable lithium-ion battery pack. The battery pack can experience a short circuit causing it to overheat and possibly causing the outside casing to become deformed, posing a potential hazard to consumers. There have only been seven (7) confirmed reports of incidents of the problem worldwide, and while no injuries have taken place, Nikon Inc. has initiated this recall of the affected lot numbers as a reflection of its commitment to safety and product quality. We are asking that owners of the affected battery pack contact Nikon Inc. to initiate a free product exchange.
The Nikon EN-EL15 battery pack is provided as a supplied accessory with the purchase of Nikon’s digital SLR D800, D800E, D7000 cameras and the Nikon 1 V1 advanced camera with interchangeable lens. It is also sold separately at retail under Nikon’s model number 27011. The EN-EL15 battery pack involved in this recall was first distributed by Nikon in March 2012 and is still being sold at retail.
No other Nikon battery packs are involved in this recall. Nikon’s digital SLR D800, D800E, D7000 cameras and Nikon 1 V1 advanced camera with interchangeable lens as well as any other Nikon cameras are also not subject to this recall.
There was a third-party battery back for the F36—the REMOPAK—which was actually introduced before the genuine Nikon cordless battery pack. I don't know that you're any more likely to find one of these for sale without the F36 though.
