XTAR AA 3500mAh LiFePO4 Disposable

The XTAR AA 3500mAh Lithium Iron Phosphate (LiFePO4) battery is a high-performance, eco-conscious power solution designed for users who demand reliability, long-term storage capability, and consistent performance across extreme conditions. Unlike traditional NiMH or alkaline batteries, this AA-sized lithium iron phosphate cell offers a significant upgrade in energy density, durability, and safety — making it ideal as a backup power source for critical AA-powered devices such as torches, GPS units, digital cameras, and handheld radios.

One of its most notable advantages is its low self-discharge rate. With a self-discharge of less than 1% per month, this battery retains over 80% of its capacity after two years of storage, meaning it remains fully charged and ready to use even after long periods of inactivity. This makes it an excellent choice for emergency preparedness kits, hiking packs, or survival gear where reliability is essential.

The battery supports a continuous discharge of up to 2.5A, which is ideal for high-drain devices that require sustained power output. It also delivers a 4A pulse discharge capability, enabling short bursts of high current without voltage drop — perfect for devices that need sudden power spikes, such as camera flashes or signal transmitters.

Engineered for extreme environments, the XTAR AA 3500mAh LiFePO4 operates efficiently in temperatures ranging from -40°C to +60°C, making it suitable for use at extreme latitudes and altitudes. Its robust construction ensures stable performance in harsh weather, without risk of swelling, leakage, or thermal runaway — a critical safety advantage over other lithium chemistries.

Weighing just 15 grams, this battery is exceptionally lightweight, adding minimal bulk to your gear. The battery is 100% leak-proof, free from toxic heavy metals like mercury, lead, and cadmium, and fully recyclable — aligning with eco-friendly outdoor practices and reducing environmental impact.

Designed for long-term stability, the XTAR AA 3500mAh battery offers a 10 year storage life when kept in optimal conditions.
