Review on Rechargeable AAA Lithium Batteries With Micro USB Charging Port - 1000 Cycle, 1.5V/400MAh - Pre-Charged, 4/Pack by Brando Carpenter

Preface: eveyone better be jumpin' on the rechargeable train. It is absolutely the only viable future.1. Less waste than regular batteries (and yeah we all know we aren't supposed to throw batteries away with our regular trash, yeah? But who actually knows where to take them? And who is actually disposing of them properly?)2. Safer. No chance of leaky, corrosive chemicals.3. Cheaper. Yes the up front cost is more, but they pay for themselves.4. Long lasting life. I have them in my toothbrush, something I use 2x every day at least, and these batteries last 1.5-2 months.5. Quick charge. They take maybe an hour to fully charge!6. Convenience. Even if you have self-centered interests, these are still for you. You don't have to remember to buy more batteries. Like ever. Never again.All in all, these batteries are must-haves and worth the initial investment.
