Questions about this item

How long will the 1300mAh capacity last during continuous shooting?

The 4.81 Wh rating gives a practical runtime that varies with camera model, shooting mode and temperature; expect fewer frames per charge in cold weather or with GPS and Wi-Fi active.

Does the battery heat up noticeably during all-day use?

Built-in over-heating protection limits temperature rise, and lithium-ion chemistry at 3.7 V runs cool under normal loads; the pack stays within safe limits during extended sessions.

Which Olympus charger do I need to recharge this pack?

It works with the Olympus LI-90C or UC-90 chargers that you already use for the original Li-90B or Li-92B cells.
