Fujifilm NP-W126S Lithium-Ion Battery for X-Pro1, X-E1, X-M1, X-A1

Product Information

This article tries to help with the right choice due to extensive testing of capacities and heat characteristics of several available brands. Power products are tested to the highest standards and manufactured using high quality components to deliver outstanding performance. The risk of damage a faulty battery can cause doesn't compare favourably to the minor inconvenience of restoring your settings at a press of a button (if you model is compatible with X Acquire). Genuine Fuji NP-W126S rechargeable lithium ion battery which is suitable for models including the Fuji X-T2, X-Pro2, X-T10, X-E2S, X-A2, HS50EXR, HS33EXR and HS30EXR digital camera models.

Enhanced version of the Fujifilm NP-W126, with more effective heat dissipation and voltage metering capabilities to more accurately measure remaining battery levels. For using the maximum power of your X-T2 or X-Pro2 mirrorless camera, the Fujifilm NP-W126S Li-Ion Battery Pack has been designed to better manage heat and ensure lightning fast camera performance. I think this also means that the charger is unable to communicate with the control microchip inside the battery (if any present, like laptop batteries all have it long since) so not only a thermistor may matter. Fujifilm NP-W126S is a high performance lithium-ion rechargeable battery that gives long term use with repeated charges. This is mostly apparent on almost empty batteries — while the camera shows that the battery is still OK, it can actually be almost empty.While the original battery shows mostly evenly distributed heat on its surface, the noname battery has much higher temperature in a smaller rectangle in the middle. Offering the proper size of the battery shell, the NC-BP004 fits that battery slot of the compatible Fujifilm cameras perfectly. Only the batteries with the lowest capacities don’t perform that well in this test — while DSTE was only about 4-5 degrees warmer, the noname brand started swelling, probably due to higher power load of the camera making 4K recording.

It can power two batteries at the same time while still being much smaller than the original one, and it can be powered off a power bank, too. The battery has a high capacity of 1140 mAh plus several safeguards including overcharge and over-discharge protection. Some batteries behave very similarly and often probably are just different brands for the very same product from some Chinese factory. Reading your subsequent comments about indeed informing others and you caring about misleading, illegitimate products, etc, I don't understand why your initial response to highlighting products with dead contacts was what it was, i.All sufficiently modern batteries have a chip inside, be it camera batteries, or laptop batteries, and I think smartphone batteries also have a chip inside, too - it communicates with the charger and reports the capabilities of the battery (i. This also applies to accessories that are supplied with the camera including batteries which may have a lower optimum performance level/life expectancy.
