Questions about this item

How often will the 2400mAh lithium-ion cells need replacing under normal use?

Lithium-ion packs typically last several hundred charge cycles; capacity gradually drops, so plan on new batteries when run time becomes too short for your shooting sessions.

What stops the 7.4V 2400mAh packs from delivering full power during long bursts?

The built-in protection circuit cuts output if temperature, voltage or current exceed safe limits, so sustained high-drain shooting may trigger a temporary shutdown.

Do the batteries get hot or draw extra power when left in the camera all day?

Self-discharge is very low; the packs stay cool in standby and only warm slightly during active shooting thanks to the over-heating protection circuit.
