Ostation 1.5V AA Rechargeable Lithium Batteries 2100mAh (4-Pack)

𝗖𝗘𝗦 𝗔𝘄𝗮𝗿𝗱-𝗪𝗶𝗻𝗻𝗶𝗻𝗴 𝗦𝗺𝗮𝗿𝘁 𝗖𝗵𝗮𝗿𝗴𝗶𝗻𝗴: The world’s first AA rechargeable battery with built-in BMS. A smart chip inside communicates with Ostation 2 series chargers to dynamically regulate current and temperature, delivering safer, more efficient Li-ion charging (Note: BMS means Battery Management System. Chargers sold separately.) 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻, 𝗜𝗻𝘀𝗶𝗱𝗲 & 𝗢𝘂𝘁: 5 layers of protection guard against overheating, overcurrent, overcharge, over-discharge, and short circuits. Dual-layer encapsulation resists everyday drops, while gold-plated copper positive contacts reduce resistance to prevent overheating and power loss. Multiple Ostation 1.5V Li-ion batteries deliver stable performance, even when used together in the same device 𝗕𝗮𝘁𝘁𝗲𝗿𝗶𝗲𝘀 𝗥𝗲𝗮𝗱𝘆 𝗙𝗮𝘀𝘁𝗲𝗿, 𝗟𝗮𝘀𝘁𝘀 𝗟𝗼𝗻𝗴𝗲𝗿: Rechargeable with any 1.5V Li-ion battery charger. When used with Ostation 2 Series chargers, these batteries fully charge in just 2.5 hours—faster than most other Li-ion batteries on other chargers. Each battery supports 1,000+ recharge cycles, saving money and reducing waste 𝗟𝗼𝗻𝗴𝗲𝗿 𝗥𝘂𝗻𝘁𝗶𝗺𝗲 𝗳𝗼𝗿 𝗛𝗶𝗴𝗵-𝗗𝗿𝗮𝗶𝗻 𝗗𝗲𝘃𝗶𝗰𝗲𝘀: With 3150mWh (2100mAh) capacity, these lithium batteries deliver extended power for demanding devices like camera flashes, gaming controllers, flashlights, and microphones, reducing the hassle of frequent battery swaps 𝗖𝗼𝗻𝘀𝘁𝗮𝗻𝘁 𝟭.𝟱𝗩 𝗢𝘂𝘁𝗽𝘂𝘁: Unlike 1.2V NiMH batteries, these lithium AA batteries maintain a steady 1.5V output, keeping voltage-sensitive devices such as security cameras and doorbell cameras running at peak performance—an ideal replacement for disposables 𝗥𝗲𝗹𝗶𝗮𝗯𝗹𝗲 𝗣𝗼𝘄𝗲𝗿 𝗶𝗻 𝗘𝘅𝘁𝗿𝗲𝗺𝗲 𝗧𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲𝘀: These Li-ion batteries operate reliably from -4°F to 140°F (-20°C to 60°C), perfect for outdoor devices including security cameras, trail cameras, GPS units, and other equipment exposed to harsh conditions.
