🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Frequently Asked Questions

This battery is compatible with iFLYTEK SR302 and SR302 Pro smart recording pens. The SR302 Pro was released in September 2021, featuring a 2.0-inch display, 32GB storage, and supports up to 15 meters of recording distance. The device does NOT support Wi-Fi or Bluetooth — it is designed for offline use. If your SR302 or SR302 Pro recording pen won't hold a charge, this is the correct replacement. For reference, the official iFLYTEK replacement battery sells for ¥99 (approx. $14). Please check your original battery before purchasing.

This battery has a capacity of 2000mAh and a rated voltage of 3.7V. Charge limit voltage is 4.2V. It is a Li-Polymer battery built with grade A cells and is CE and RoHS certified. The original SR302 and SR302 Pro support standard 5V/2A Type-C charging. The device offers up to 15 meters of recording distance with smart noise reduction.

Professional installation is recommended. The iFLYTEK SR302 series recording pen has a sealed design. Replacing the battery requires careful opening of the device casing to avoid damaging internal components or the display. If you choose to DIY, watch a teardown tutorial before starting and use proper plastic opening tools. The device does not have water resistance, so no adhesive heating is required. Always use a standard 5V/2A Type-C charger after replacement and never reuse a battery after removal.
