"It's almost 2026, and yes, we still need batteries. But it no longer makes financial or ecological sense to keep using disposable alkaline batteries. For me, I need mostly the good old AA battery, but I also need AAA, C, D, and even the blocky 9V PP3. There are some great rechargeable batteries out there from companies such as and , but the drawback there is that you need a specific charger, and who needs "yet another thing" in their life, am I right?"
"It would be cool if you could just plug a USB cable into a battery, wouldn't it? Well, USB-C ports and battery charge circuitry are small enough, and battery chemistry is good enough to let that happen. I've been testing a lot of USB rechargeable batteries, and the brand that's consistently been a winner for me is . The company offers a wide range of rechargeable lithium-ion batteries, AAA, AA, C, D, and 9V, as well as assorted bundles."
Disposable alkaline batteries are increasingly unjustified financially and ecologically, yet households still require AA, AAA, C, D, and 9V cells. Traditional NiMH rechargeables demand dedicated chargers, adding clutter and inconvenience. USB-C ports and compact charge circuitry now allow batteries to include built-in USB charging, simplifying use. A company offers USB-rechargeable lithium-ion batteries in common sizes with kits that include batteries, a 4-way charge cable, and a storage box. The batteries match alkaline size, voltage, and power, claim around 1,000 recharge cycles, and AA cells tested near 2,550mAh, providing excellent life in devices designed for disposables.
