SPYONG USB Rechargeable AA Lithium Batteries

USB Charging Design: Unlike regular rechargeable batteries, SPYONG AA batteries use a USB charging method. Simply charge them via any USB port—like on a computer, wall socket, mobile power bank, or car. The included 4-in-1 Type C adapter allows you to charge up to 4 batteries at once, making it quick and easy.

Long Battery Life: These batteries can be recharged over 1500 times, replacing more than 1500 single-use alkaline batteries. This not only saves you money but also reduces waste and environmental pollution.

High-Density Energy Formula: SPYONG’s advanced lithium-ion technology provides stronger, more stable performance. The batteries resist overheating and short circuits, offer ultra-low self-discharge, and maintain a long standby time of over a year.

Fast Charging: These batteries charge much faster than traditional ones. With a 40-minute full charge, the batteries reach 20% in just 5 minutes. The built-in LED indicator lets you know when they’re fully charged, preventing damage to your devices.

No more dealing with leaks or slow charging! SPYONG batteries are designed for convenience and durability.
