It fits the EOS 5D Mark II, EOS 5D Mark III, and EOS 7D, along with several other Canon EOS bodies that share the same LP-E6 battery slot. The cell matches OEM voltage and contact layout to work with Canon's in-body BMS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLP-E6 and LP-E6N cross-compatibility:\u003c\/strong\u003e\n    The LP-E6N is a revised spec that added a third communication contact for more accurate charge-remaining data on newer Canon bodies. Both part numbers use the same physical housing and 7.4V rail — the extra contact is simply read if the body supports it and ignored if it doesn't.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Canon in-body charger and an OEM LC-E6 dock. The BMS handshake completed on first cycle in both cases, and the battery-remaining indicator populated correctly after one full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on LP-E6 bodies:\u003c\/strong\u003e\n    Canon's battery management reads charge-remaining against a mapped discharge curve. On a fresh cell, run one complete charge cycle through the camera body or OEM charger before a shoot — the display can show erratic percentages until the BMS establishes the cell's actual curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling drawing down the LP-E6 cell faster than stills-only shooting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a Speedlite is attached, capacitor recharge draws a sustained current burst after every shot. On the 5D Mark II, that adds to continuous autofocus and mirror drive current simultaneously. A 2000mAh cell at 7.4V handles this load, but the BMS will step down output voltage earlier than during stills-only use to protect the cell. If flash recycling slows noticeably, that's the BMS throttling current — not a faulty battery. Switch to a fresh cell for high-volume flash work.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCanon body showing \"incompatible battery\" or refusing to power on with a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS authentication check. Canon bodies verify the battery communication contacts before enabling full operation, and a new cell that hasn't completed a charge cycle can fail that check on first install. Remove the battery, place it in the OEM LC-E6 charger until the green light confirms a full charge, then reinsert. If the body still rejects it, power cycle by holding the shutter with the battery removed for ten seconds to clear residual capacitor charge before reinserting at 8.0V resting voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333731352666,"sku":"BWCS-LPE6MX-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333731385434,"sku":"BWCS-LPE6MX-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333731418202,"sku":"BWCS-LPE6MX-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LPE6MX-1.webp?v=1778213084","url":"https:\/\/batteryweb.com\/products\/canon-eos-5d-mark-ii-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
