NP-FW50 Battery 2-Pack and USB Dual Charger for Sony A6000, A6500, A6300, A6400, A7, A7II, A7RII, A7SII, A7S, A7S2, A7R, A7R2, A55, A5100, RX10 RX10II (Micro USB Port,1500mAh)

Bought these as backups on a video shoot. They work beautifully on the Sony A7 RII and the double charger is excellent to stagger charging to always have a fresh one at the ready. Good quality and the camera had no problem reading the battery charge level. I find no difference from the Sony batteries.

I was very undecided if I should invest into the old camera, but it turned out to be a very good improvement. Battery life seems better than ever and that constant charging of the original batteries is now gone.

Not bad for price, I'm using from few weeks work well...

Easy to use, compact for travel.

i bought this in early January. I think it worked because I put the batteries on it and took them off when it glowed green, but I can't remember if the leds were red when first put on it. Been too busy with work and Covid so I finally needed to charge my batteries and I pulled this charger out. It doesn't work. When I put my depleted batteries on it and plug it into my USB, all I get are green LED lights. I have put on batteries that were about 50 to 75% charge and some that were down to 1 bar. I have swapped it with different USB wall warts and it won't work. The charger is a dud which is a shame because that's primarily why I bought it.

One of the replacement batteries is a dud, the charger shows this by flashing red.
