The battery I received was manufactured at 2020.3 (ICA1G) but it doesn't last longer than an hour during an active photoshoot. Very disappointed because the old battery (manu. 2012.7 (SGH1B)) I have last just as long and I bought a new one to restore the duration to 2-2,5 hours as when I first bought the camera incl. Battery. Had I known this I would have bought a thrid party battery. Delivery time was on point though.
