Questions about this item

How often will the Li-ion cells need replacing?

The 2250 mAh pack is rated for hundreds of charge cycles; typical camera use sees several years before capacity drops noticeably.

What limits continuous shooting on the Olympus E-M1 Mark II?

The 16.65 Wh capacity sets the total energy available, so sustained bursts drain the 7.4 V cells until recharge.

Does the battery get hot during all-day video recording?

Normal operation stays within safe temperatures; the 52.60 × 44.00 × 20.00 mm housing dissipates heat without a fan.
