Sharp-eyed users may have noted that Canon’s EOS-1D X camera is equipped with a slightly different battery pack than previous versions of the EOS-1D or EOS-1Ds. There may be some confusion regarding the differences and compatibility of older and newer cameras and batteries, so we’d like to take this opportunity to clarify matters a bit, and help prevent any misinformation from occurring among owners or dealers.
Canon introduced the Lithium-Ion battery pack LP-E4 in 2007, with the launch of the EOS-1D Mark III camera. Significantly lighter than the Ni-MH type pack it replaced, it also powered the camera for longer periods of time, and was noticeably smaller as well. The LP-E4 battery pack has been used in the EOS-1Ds Mark III and EOS-1D Mark IV cameras as well, and remained available until well into 2012.
With the launch of the newest EOS-1D X camera, however, the LP-E4 has been replaced in the Canon line by its companion LP-E4N battery pack. The new LP-E4N battery is readily identifiable by its gold-on-black lettering, compared to the previous LP-E4 battery’s silver lettering.
Aside from the gold-colored labeling, there are two fundamental differences to be aware of:
Higher battery capacity
The new LP-E4N is rated at 2450 mAh, vs. 2300 mAh for the LP-E4 pack. In spite of this difference, it remains compatible with the EOS-1D Mark III, Mark IV, and the EOS-1Ds Mark III (as explained below)
Compatible with new Japanese safety regulations for Lithium-Ion rechargeable batteries
Some minor changes have been made in the interest of safety, to conform with the latest laws in Japan for rechargeable Lithium-Ion battery packs
With the new LP-E4N battery, Canon has introduced an updated battery charger, the LC-E4N. Virtually identical in appearance to the previous LC-E4 charger, which was marketed at the same time as the original LP-E4 battery pack, the new charger has been slightly modified to accept the slightly more powerful LP-E4N battery without any minor malfunctions. The new LC-E4N charger replaces the LC-E4 in Canon’s line-up.
Since the LC-E4N charger’s shape and electronic contacts are the same, it definitely can charge the older LP-E4 battery packs, as well as the latest gold-labeled LP-E4N batteries. It also uses the same type of removable AC plug, and is multi-voltage, so a simple plug adapter is all that’s needed for virtually any AC input from 100~240 volts. No voltage converter unit is needed for international travel!
LC-E4N will charge a battery pack in roughly two hours (about 130 minutes for the slightly higher-voltage LP-E4N battery pack). Two batteries can be inserted simultaneously in the charger; the pack installed first will be charged first, an then the second one will be charged. LEDs indicate the approximate level of charge; all three LEDs illuminate green steadily (no blinking) when a battery pack is fully charged.
