XTAR AA 4150mWh 2500mAh (4)
The XTAR AA 1.5V 4150mWh battery is a high-capacity powerhouse designed for users who need maximum endurance without the voltage drop-off of traditional rechargeables. Bridging the gap between the everyday 3300mWh cells and the professional 4300mWh series, this battery is the "sweet spot" for high-performance electronics.
XTAR AA 1.5V 4150mWh: High-Capacity Lithium Precision
The Perfect Balance of Power and Longevity.
Traditional Ni-MH rechargeable batteries often struggle to keep up with modern gadgets because their voltage drops as they drain. The XTAR 4150mWh Li-ion battery changes the game by maintaining a rock-solid 1.5V output from the first minute of use until the cell is depleted. It provides the consistent "punch" your devices need to operate at peak efficiency.
Includes
- 4 x Batteries
- 1 x Plastic Case Holds 4 Batteries

Expert Tip: If you are using these for a professional shoot or critical security device, the 4150mWh capacity provides that extra "buffer" of power over standard lithium cells, ensuring you don't run out of juice mid-task!
Key Features
- Constant 1.5V Output: Engineered to provide a steady 1.5V stream, ensuring your devices don't enter "low power mode" prematurely.
- Massive 4150mWh Energy: High energy density means fewer battery swaps and longer runtimes for high-drain equipment.
- 1200+ Recharge Cycles: One XTAR battery is built to outlast 1,200 disposable alkalines, significantly lowering your total cost of ownership and environmental impact.
- Ultra-Fast Charging: Capable of reaching a full charge in approximately 2 hours when used with a compatible XTAR 1.5V Li-ion charger.
- Smart Safety Circuit: Every cell features an integrated Protection Circuit Board (PCB) to prevent over-charging, over-discharging, and short circuits.
- No Memory Effect: Charge at your convenience without worrying about reducing the battery's total capacity over time.
Universal High-Drain Performance
This battery is specifically optimized for devices that require high voltage and consistent energy delivery:
- Professional Audio: Wireless microphones and in-ear monitors.
- Smart Home Security: High-torque smart locks and electronic deadbolts.
- Photography: Speedlights, camera flashes, and wireless triggers.
- Gaming Gear: VR controllers and high-performance wireless gaming mice.
- Motorized Toys: RC cars and high-speed household appliances.
