بطارية باناسونيك DMW-BLJ31 ليثيوم أيون قابلة للشحن (7.2 فولت، 3100 مللي أمبير)

I've been using this battery for my camera, and it holds a charge noticeably longer than the original one I had—easily lasting through a full day of shooting. The 3100mAh capacity really makes a difference during long sessions.

It fits snugly into my Lumix S1 and holds a charge for a full day of shooting landscapes. I’ve already gone through two full cycles without any drop in performance—solid backup for long trips.

Battery life is solid—I’ve shot over 800 frames on a single charge with my Lumix S1. The 3100mAh capacity lasts noticeably longer than the OEM battery I replaced. Only minor issue is it’s a bit snug in the charger at first.
