MB-264 Ultimate
battery replacement for Leica BP-SCL6

Mathorn MB-264 Ultimate is a premium replacement battery for the Leica BP-SCL6, offering a nominal capacity of 2600 mAh. Powered by selected NCR lithium-ion cells, it delivers consistent power even under high energy demands typical of high-resolution sensor cameras and advanced video features. This makes the MB-264 Ultimate a reliable power source for both everyday photography and extended shoots with Leica Q and SL systems.

More Energy, Greater Shooting Freedom
The original Leica BP-SCL6 battery offers a capacity of 2200 mAh, while the Mathorn MB-264 Ultimate provides 2600 mAh – an extra 400 mAh, or approximately 18% more capacity. This higher power reserve gives you greater flexibility during full-day shoots, travel, intensive sessions, or video recording, reducing the need to swap batteries or recharge frequently. The high-performance Mathorn battery excels during demanding camera functions, such as computational photography, burst shooting in uncompressed RAW format, and high-quality video recording.
Stable Power Delivery During Heavy Use
The Mathorn MB-264 Ultimate utilizes carefully selected, high-drain NCR lithium-ion cells that ensure a stable power supply during photography and videography. The battery effortlessly handles peak power demands, such as high-speed burst shooting, intensive in-body image stabilization (IBIS) operation, or high-resolution video recording.

Durability and Minimal Self-Discharge
Designed for long-term use, the cells in the MB-264 Ultimate retain at least 80% of their initial capacity after 500 charge/discharge cycles.
The battery exhibits exceptionally low self-discharge during extended storage. Long-term testing demonstrates an average voltage drop of just ~0.2% per month and under 3% over a full year. This ensures the battery can remain in your kit bag for months while staying fully ready for immediate use.
Full Leica System Compatibility
The Mathorn MB-264 Ultimate is fully compatible with cameras using the Leica BP-SCL6 battery and supports dedicated system chargers.


Protection Circuitry and V1 Flame-Retardant Housing
A built-in Battery Management System (BMS) continuously monitors performance to protect the cells against overcharging, over-discharging, overcurrent, and short circuits. The durable enclosure, crafted from V1 flame-retardant material, adds an extra layer of protection during daily use.
