NiMH Rechargeable AA or AAA

Stop wasting your money on disposable batteries!  I personally use these in every device in my household If you don't believe the hype, $10-$15 bucks isn't a huge expense to try it out yourself :) Nothing beats first hand experience. Be the expert, not the uninformed. Major benefits of using NiMh rechargeables: Full power for the life of the battery: Alkalines loose power as they run down. They don't leak: and you know alkalines leak and ruin your stuff all the time. ReCyko+ lasts for more 1000 charges: One battery vs. 1000 alkalines! Low Self Discharge: 75% charge retention at 12 months The best option for Beta QR flashlights: or any device for that matter. Same performance as expensive lithium disposables: without the waste. Never (ever) use disposable alkaline batteries again! Don't worry, I used to be just like you, buying costco packs of alkaline batteries and feeling bad about the incredibly insane amount of waste...of raw materials, but also money. Disposable batteri
