1. Product Overview
The XTAR Next Generation 1.5V AA Lithium Rechargeable Batteries are designed to provide a stable 1.5V output, making them suitable for a wide range of electronic devices. These batteries offer a capacity of 2000mAh (3000mWh) and can be recharged up to 1200 times, offering an economical and environmentally conscious alternative to disposable alkaline batteries.
Each battery integrates a high-efficiency charge and discharge management chip, utilizing 2.4MHz synchronous rectified buck discharge technology. This ensures a constant 1.5V output when the battery voltage is above 3.3V. When the battery voltage drops below 3.3V, the output voltage decreases linearly, signaling a low power state to the device.
