First off, 16 PACK?! That’s enough to power my entire gadget drawer for years. These Granicell AAs aren’t just batteries—they’re tiny energy titans with a 2800mAh punch.

Low self-discharge is the real MVP here. Left them in my emergency flashlight for 6 months, and they still fired up like I’d charged them yesterday. Take that, zombie apocalypse.

Tested them in my DSLR during a weekend shoot—no ‘low battery’ panic. Outlasted my Eneloops by 20% (yes, I timed it). Game controllers? Still running after 3 Mario Kart tournaments.

Eco-nerd bonus: Solar-precharged and heavy-metal free. My inner Greta Thunberg approves. The PVC jacket feels sturdy, though the shrink-wrap packaging could use less plastic.

Cons? My dumb charger took 5hrs to juice them fully. Also, they’re slightly fatter than alkalines—had to wrestle them into my vintage Walkman. Still, at 1300 cycles, I’ll be recycling these in 2035.
