Doc Johnson Alkaline Batteries - 4 AA

I was worried these would die mid-use, but they kept my toy going for weeks without any drop in power. Way better life than the cheap ones I used to grab from the corner store.

Grabbed these for my vibe and they've outlasted the cheap ones I usually buy by a solid margin. Four AAs in the pack, no leaking so far after a few weeks of regular use.

I was a bit skeptical about buying batteries from this company, but these AAs have genuinely lasted longer in my wireless mouse than the usual store brand. The extra power they advertise is real, and I haven't had to swap them out in over three weeks of daily use.
