AKTTKA 4 Pack Rechargeable D Batteries, 1.5V Lithium LR20, 500+ Cycles

【9250mWh High Capacity & 1.5V Constant Voltage】Built with a massive 9250mWh lithium cell, these rechargeable D batteries deliver 3-5x longer runtime than standard alkaline D batteries. Unlike traditional 1.2V NiMH batteries that lose power mid-use, our 1.5V constant voltage technology keeps your devices running at full performance from start to finish. Ideal for high-drain devices like torches, camping lights, and motorised toys that demand consistent, reliable power. 【USB-C Direct Fast Charging & 4-in-1 Cable Included】No bulky charger needed. Each battery features a built-in USB-C port for direct charging from any USB adapter, laptop, power bank, or car charger. Full charge in just 5.5 hours — significantly faster than NiMH alternatives. The included 4-in-1 USB-C charging cable lets you charge all 4 batteries simultaneously from a single USB port, maximising charging efficiency for multi-battery devices. 【500+ Recharge Cycles – Save Money & Reduce Waste】Each battery supports over 500 charge-discharge cycles, replacing 500+ disposable alkaline D batteries per cell. That means 2,000+ disposable batteries saved across this 4-pack alone — massive long-term savings plus a significant reduction in battery waste. Low self-discharge technology retains over 80% charge after 12 months of storage, always ready when you need them. 【Built-in Smart Safety Chip – Worry-Free Protection】Every battery is equipped with an advanced safety chip providing comprehensive protection against overcharge, over-discharge, over-current, short circuit, and overheating.
