The biggest reason to buy is the package pairing: two 11.1V 3200mAh lithium-ion replacement batteries plus a dual fast charger with an LCD that shows charging status, making it easy to keep spares charged for long shoots or travel. The set is a practical alternative for users of EN-EL4 series batteries and those who use Nikon D2\/D3 series or D300\/D700 bodies with a compatible grip.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement battery:\u003c\/strong\u003e Each 3200mAh lithium-ion cell delivers extended runtime for DSLR sessions and shoots where original batteries run short.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide input voltage:\u003c\/strong\u003e The charger accepts 110-240V worldwide input so it is convenient for travel and international shoots without a bulky voltage converter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual fast charging:\u003c\/strong\u003e The LCD dual charger can charge two batteries simultaneously and displays each battery's charging status and capacity for quick checks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart MCU control:\u003c\/strong\u003e The intelligent control system identifies battery voltage and applies CC\/CV charging with pre-charge and 0V activation to protect cells and extend service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e The batteries are compatible with Nikon EN-EL4, EN-EL4a and EN-EL4e models and the charger is compatible with chargers MH-21 and MH-22 formats.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003ePhotographers using legacy Nikon bodies such as D2, D3 series, D300, D300S and D700 with MB-D10 or MB-40 grips will get the most value, especially if they need two spare batteries and want a single charger that handles both.
