Canon LP-E17

The LP-E17 is the factory lithium-ion battery for a large slice of Canon's EOS lineup, rated at 7.2V and 1040 mAh. It is built to give consistent runtime to photographers and videographers working across mirrorless and DSLR bodies alike.

Coverage includes the full-frame and APS-C EOS R8, R10, R50 and RP mirrorless cameras, the Rebel SL3, SL2, T8i, T7i, T6s and T6i DSLRs, and the M6 Mark II. Check the exact body before ordering, since Canon's mid-range lineup spans several sensor formats.

The genuine battery's main advantage is reliability: no error messages, no disabled burst mode or video limits like some low-cost alternatives can trigger, and an on-screen charge percentage that can be trusted. Overcharge and overheat protection are built in as well.

A second LP-E17 charged and ready in the bag is common practice for event and wedding photographers, where a dead battery mid-shoot is not an option. With 6,600-plus Amazon reviews averaging 4.8 stars, it is one of the best-reviewed camera batteries on the site.
