BLX-1 Replacement Battery 2 Pack for Olympus OM-1 - USB-C Fast

In this review of the BLX-1 replacement battery 2 pack, the reviewer finds these cells most useful for photographers who need reliable spare power and fast top-ups on the go. The single biggest reason to buy is the built-in USB-C fast charging which cuts charging time and eliminates the need for a separate external charger, making this kit a practical choice for travel and extended shoots with Olympus OM System OM-1 or OM-1 Mark II cameras.

Key Features

• Battery capacity: Each cell offers 2600 mAh at 7.4V, providing extended shooting time relative to many third-party packs.
• Built-in USB-C charging: The integrated USB Type-C port allows direct charging from a power bank or car adapter, reducing reliance on a dedicated charger.
• Fast charging indicator: A red charging light and a green full indicator make it easy to know when a battery is ready without guessing.
• Decoded chip compatibility: The new fully decoded chip communicates like the original, avoiding camera error messages and ensuring reliable battery reporting.
• Protection features: Internal safeguards protect against short circuits, over-current, overheating, and over-charge during normal use.
• Versatile charging options: The battery will charge from common USB power sources and charger kits, adding convenience on location.

Who It's For

Photographers using the Olympus OM System OM-1 or OM-1 Mark II who want spare batteries that charge quickly and can be topped up from a power bank will find the BLX-1 pair especially practical. Reviewers noted the convenience of USB-C charging and the absence of camera error messages, which makes these a good match for travel shooters and event photographers who need dependable backups.

Users who require official-brand cells for extended manufacturer support or very long-term warranty coverage should consider original manufacturer batteries; this pack is a third-party replacement designed for compatibility and convenience rather than OEM warranty alignment.
