AKTTKA Rechargeable AA 1.5V Lithium Batteries 4-Pack, 4070mWh High Capacity

4070mWh IN EVERY CELL — MORE RUN TIME BETWEEN CHARGES：Density is what buys you time. With 4070mWh packed into each AA, AKTTKA widens the gap between charges for smart locks, game controllers, flashlights, cameras, wireless accessories, and the everyday electronics around the house. Fewer interruptions, fewer mid-task battery swaps, fewer trips to the drawer. The power is still there when you reach for the device. USB-C RECHARGE — ONE CABLE, NO DOCK TO BUY：The cable you already own does the work. Pair these rechargeable AA batteries with the included 1-to-4 USB-C cable and all four refill at the same time from a wall adapter, laptop, power bank, or car charger. Nothing proprietary, no charging station hogging an outlet. Plug in wherever you are and let the set fill up while you get on with your day. 1.5V CONSTANT VOLTAGE — STOP LOW-BATTERY WARNINGS: Standard 1.2V NiMH rechargeable batteries may lead to dimming lights, laggy controllers, and sensor errors. AKTTKA 1.5V lithium batteries hold a steady 1.5V output throughout the discharge cycle, so your devices run at their best — bright flashlights, responsive gaming controllers, and reliable smart home sensors. Consistent voltage, consistent performance. A MATCHED SET OF FOUR — CHARGED TOGETHER, USED TOGETHER：Four cells in one box means one complete set for one device, all sharing the same capacity and the same charging history. When the set runs down, pull all four, put all four on the 1-to-4 cable, and they come back up together — no half-charged stragglers, no mixing fresh and tired cells inside the same gadget. Rotation stays simple, downtime stays short, and last-minute runs for disposable AA batteries stop happening. 500+ RECHARGES PER CELL — 2,000+ ACROSS THE 4-PACK：Each AA is built for 500+ charge cycles — more than 2,000 reuses from one 4-pack. Rotate them through smart locks, Xbox controllers, LED flashlights, electric toothbrushes, wireless mice and keyboards, doorbells, and Christmas lights, then charge and go again. Six built-in protections guard against overcharge, over-discharge, overcurrent, short circuit, overvoltage, and overheating. Less waste in the trash, lower cost every time you recharge.
