The Fujifilm NP-W126S 1260mAh Li-ion Rechargeable Battery in black is a high-quality accessory designed for Fuji and Fujifilm cameras. With a capacity of 1260mAh, this battery provides long-lasting power for extended shooting sessions without the need for frequent recharging. The Li-Ion chemical composition ensures efficient and reliable performance, making it a great choice for photographers who require a dependable power source for their camera equipment.
This updated version of the battery does alleviate some of the heat related issues with the first battery, thus helping increase battery life to the battery and camera use. I use these batteries for my X-T1 and I have seen a significant decrease in heat and slightly longer battery life. A must have for any Fujifilm X user. Slightly expensive, but worth the investment for extra batteries and addressing the first version's issues.
