For use with compatible Sony cameras, this SB-U98 PD Sony BP-U Lithium-Ion Battery from IDX System Technology offers an alternative power source while in the field with an integrated USB output port and 98Wh capacity. Thanks to its updated software, the battery has improved accuracy in your camera's viewfinder indicator for better power monitoring. One D-Tap output and one USB port can power additional camera accessories or charge the battery once depleted. A 4-stage LED indicator displays the total remaining battery, while overcharge, overdischarge, and overcurrent protections maintain its internal circuitry.
