FAQs:

Is there a built-in indicator for charging progress?

Yes, the MB-254 features an integrated LED charge status indicator when using USB-C input. This provides real-time visual feedback on the charging stage, helping you monitor battery status without needing to connect to a camera or charger display.

What type of lithium-ion technology is used in the MB-254?

The MB-254 utilises advanced NCR (Nickel Cobalt Rechargeable) lithium-ion cells, which offer a higher energy density and superior thermal performance compared to standard ICR cells. This results in more efficient power delivery and reduced heat during operation.

How does the battery protect against overcharging and thermal damage?

The MB-254 incorporates both active and passive electronic protection circuits, including thermal cutoff, overcharge protection, over-discharge prevention, and short-circuit safeguards. These systems are embedded directly within the battery to ensure safe, reliable operation even in harsh environments.
