ENEGON Rechargeable Lithium D Batteries 4 Pack, 12580mWh USB-C Charge

500+ CHARGE CYCLES, REPLACES OVER 500
DISPOSABLE BATTERIES: Each ENEGON rechargeable D battery supports over 500 full charge cycles, lasting approximately 2 to 3 years with regular use. By replacing disposable alkaline D batteries, one 4-pack eliminates up to 2, 000 single-use batteries from landfills over its lifespan, reducing both long-term battery costsSave $200+ and environmental waste for households relying on flashlights, radios, and portable fans.
12580mWh HIGH-CAPACITY LITHIUM-ION D BATTERY: Unlike standard NiMH D batteries that lose voltage as they drain, the ENEGON lithium-ion D battery maintains a constant 1.5V output throughout its full 12580mWh capacity. This extends device runtime by up to 40% compared to alkaline D batteries in lab-tested conditions. Compatible with large flashlights, portable radios, tape recorders, large electric toys, Water Heater, high-power remote controls, and gas stoves.
BUILT-IN USB-C CHARGING,
NO DEDICATED CHARGER NEEDED: Unlike traditional rechargeable D batteries that require a separate bulky charger, each ENEGON battery has a built-in USB-C port. The included 4-in-1 cable lets you charge four batteries simultaneously from any USB-C power source laptop, car charger, or power bank. The indicator light flashes while charging and remains steady when fully charged, keeping you informed of the batterys charge status at all times.
INSTANT BATTERY LEVEL CHECK WITH 4-LED DISPLAY: Unlike disposable D batteries where you cannot tell remaining power, simply press the touch sensor on top of each ENEGON battery and four LED indicator bars light up immediately to show remaining charge (4 bars=100%, 3=75%, 2=50%, 1=15%). This eliminates the guesswork of dead batteries mid-use and helps you plan recharging before your next camping trip or emergency.
CONSTANT 1.5V OUTPUT UNTIL 15% REMAINING: Unlike alkaline D batteries whose voltage drops from 1.5V to below 1.0V as they drain causing flashlights to dim, fans to slow, and radios to crackle ENEGON lithium-ion batteries maintain a steady 1.5V output until only 15% capacity remains. This means your high-power devices run at full performance throughout the entire battery cycle, not just the first few hours.
