Swarovski RB-S 充電電池 適用於 AT/ST Balance

I've been using this battery for a few weeks now, and the 12-hour charge lasts through a full day of birding without any issues. It's noticeably lighter than my old one, which makes a difference during long hikes.

Swapped out the old battery this morning and it’s still holding strong after a full day of birding—the lightweight build makes a real difference on the tripod. Twelve hours feels about right so far, and it charges up without any fuss. Exactly what I needed for long sessions.

I was skeptical about the 12-hour claim, but after a full day in the field, the battery still had plenty of juice left. It's noticeably lighter than my old backup battery, which made a difference when hiking to my spot.
