AKTTKA Rechargeable Lithium AA/AAA 1.5V Batteries, Pack of 8 (4×AA 4070mWh + 4×AAA 1100mWh), USB-C Direct Charging, 1 to 4 Cable Included, for Remote Control/Scales/Thermometer/Controller

• 【Up to 40% More】 AKTTKA lithium batteries pack 4070 mWh (AA) and 1100 mWh (AAA) per cell, delivering up to 40% longer runtime than most standard 1.5V rechargeable lithium batteries on the market. Fewer charges, fewer swaps — keep your devices running longer without interruption
• 【USB-C Direct Charging】 No separate charger needed — each battery features a built-in USB-C port. AAA batteries fully charge in just 1 hour, AA in 4 hours, with the included 1-to-4 USB-C charging cable charging up to 4 batteries simultaneously. Recharge via laptop, power bank, or USB wall adapter anytime, anywhere
• 【1.5V Constant Voltage Output】 Unlike NiMH batteries that drop voltage as they drain, AKTTKA 1.5V constant voltage technology delivers stable, consistent power throughout the entire discharge cycle. Devices perform optimally until just 15% remaining capacity — no sluggish response, dimming displays, or unexpected shutdowns
• 【500+ Cycles】 Each battery supports 500+ charge cycles, replacing up to 500 disposable batteries per cell. That is approximately £250 saved per AA and £247 per AAA over their lifetime. A cost-effective, eco-friendly choice that significantly cuts long-term costs and battery waste
• 【Wide Compatibility & 6-Layer Safety】Suitable for most AA & AAA devices: remote controls, digital scales, thermometers, game controllers, wireless keyboards & mice, smart locks, LED lights, and more (max 2A discharge). Built-in 6-layer protection against overcharge, over-discharge, overcurrent, short circuit, overvoltage, and overheating. Backed by 24/7 customer support for complete peace of mind
