The SPMST 1.5V Rechargeable AA Lithium Battery is the most economical and eco-friendly alternative to alkaline AA batteries. This rechargeable lithium battery adopts top-quality battery cells and has a built-in intelligent integrated chip, which ensures the safety and reliability of the battery during use. It is particularly suitable for devices and applications that require an operating voltage higher than 1.2 volts, such as household electronic devices like game controllers, VR controllers, toy cars, cameras, door locks, and microphones. It features ultra-high capacity and 1.5V voltage output, with a capacity of up to 2800mWh/3600mAh. Boasting higher energy density, it supports a large number of charge-discharge cycles to extend its service life, with the number of cyclic charges reaching over 1500 times. Made of high-end battery materials and a special formula, it can withstand harsh outdoor temperatures (both extreme cold and heat). Its high-energy-density design enables it to tolerate extreme temperatures ranging from -40°F to 140°F (-40℃ to 60℃). It can still supply power stably in outdoor winter environments or high-temperature summer conditions, preventing unexpected device shutdowns. Warm Reminder: Please use a compatible dedicated charger to charge this battery. It comes in a storage case for easy storage.
