Questions about this item

How do I install the NP-FW50 battery in my Sony Alpha 6000 and what step do people often miss?

Slide the battery into the compartment with the contacts facing inward until the latch clicks; the step many miss is fully seating it so the lock engages.

What maintenance will these Li-Ion cells need over their service life?

Store at roughly half charge if unused for weeks, avoid deep discharge, and recharge every few months to preserve the 1650mAh capacity.

What limit appears first during continuous video recording on a Sony RX10 IV?

The 11.8 Wh capacity typically depletes before the over-heating protection circuit activates.
