Canon R6 Mark III battery compatibility: LP-E6P vs LP-E6NH

What changes on the R6 Mark III

Canon's R6 Mark III support page names LP-E6P as the standard battery. The camera can also use LP-E6NH or LP-E6N, but it does not treat them as equivalent. Canon's manual marks these older packs as partially functional and spells out the practical limits: Wi-Fi connectivity is unavailable, continuous shooting is slower, and the camera cannot use the battery's full remaining capacity. An original LP-E6 is listed as incompatible.

The limits apply with or without Canon's BG-R20 battery grip. If you shoot bursts, transfer over Wi-Fi or need predictable remaining capacity, the LP-E6P is the safer choice for this body. A compatible-looking battery label alone does not establish that a third-party pack behaves like a genuine LP-E6P.

Can you reuse an LP-E6NH from an R6 Mark II?

Yes, with the Mark III restrictions above. That makes an existing LP-E6NH or LP-E6N a useful backup, but it is not the battery to choose when full R6 Mark III functionality is important. Canon also notes that mixing an LP-E6P with an LP-E6NH/N in the grip can reduce available shots and operating time compared with using one LP-E6P by itself.

For an R6 Mark II that is staying in your kit, there is no compatibility reason to replace a healthy LP-E6NH. Canon lists LP-E6P support on the Mark II compatibility table with a firmware footnote: firmware that enables LP-E6P support allows the same continuous-shooting speed as LP-E6NH. Check Canon's current firmware information for your body before buying a new battery; the camera's exact installed version matters.

Do you need a different charger?

Canon lists its LC-E6 charger as compatible with LP-E6P, LP-E6NH, LP-E6N and original LP-E6 packs. The R6 Mark III's USB charging guidance recommends Canon's PD-E2 or PD-E1 and requires an authenticated battery in the camera. Canon cautions that other USB power supplies are not guaranteed to work correctly, so confirm the exact charger and battery combination before relying on it on a shoot.

Don't buy a multi-bay charger just because the battery has a new suffix. First check which charger you already own, whether you need to charge away from the camera, and whether the exact third-party charger explicitly lists LP-E6P support. A charger that accepts the LP-E6 shape is not proof that an untested battery pack is appropriate for the R6 Mark III.

A simple buying decision

For a new R6 Mark III spare, start with a genuine LP-E6P from an authorized camera retailer. For occasional backup, keep a genuine LP-E6NH/N you already own and accept Canon's stated limits. For an R6 Mark II, keep using a healthy LP-E6NH/N; consider LP-E6P only after checking the firmware note and your shooting needs.

Amazon currently surfaces a mix of chargers, third-party packs and camera bundles for LP-E6P searches. I couldn't verify a standalone Canon LP-E6P listing in its initial Canon-filtered results, so the Amazon button opens search results rather than a claimed exact product page. Check that the listing is for a genuine LP-E6P battery itself, not an R6 III bundle, a charger or a different LP-E6 variant. Compare seller, warranty region and return policy before ordering.
