In outdoor photography, alkaline batteries are still one of the most common power solutions. However, their high long-term cost and poor discharge performance in cold environments are hard to ignore.

Today, I’m going to introduce a true game-changer in the rechargeable battery field — the XTAR 1.5V AA CLR 4300 lithium battery.

To verify its real-world performance, I compared it against two popular NiMH batteries：Cityork 1.2V 3000mAh and EBL 1.2V 2800mAh.

Real-World Test

(1) Test Conditions

• Device: Trail camera with SIM card for image transmission that needs high power consumption.

• Environment: Outdoor environment with alternating daytime and nighttime shooting.

• Duration: 3 consecutive weeks of continuous use.

(2) Test Results

》Power Recognition and Startup

• XTAR: The camera detected the batteries at 100% power, started quickly, and operated stably — identical to alkaline batteries.

• Cityork / EBL: Even when fully charged, the camera only recognized 60% – 80% capacity.

Trail cameras typically estimate remaining power based on voltage thresholds. Since Ni-MH batteries operate around 1.2V, they are often misjudged as “low power” and shut down early.

XTAR’s constant 1.5V output effectively prevents this issue, ensuring reliable operation.

》Endurance and Energy Efficiency

After 3 weeks of continuous operation, XTAR 1.5V lithium battery Still displayed 100% battery level. The device operated normally and captured multiple videos without power loss or shutdown as Ni-MH batteries.

The XTAR lithium battery features higher energy density (2700mAh) and maintains stable output voltage, enabling devices to utilize energy more efficiently.

In contrast, the voltage of Ni-MH batteries steadily declines during discharge, often causing premature shutdowns — meaning that even with higher rated capacity, their actual usable energy is lower

To make the difference clearer, the figure below shows the discharge curves of four types of AA batteries.

From the chart we can see:

• XTAR AA CLR 4300 : Maintains a nearly constant 1.5V output throughout most of the discharge process, dropping only near the end of capacity. This ensures stable device performance and prevents early shutdowns due to voltage sag.

• Alkaline battery: Starts at a higher voltage but drops rapidly as it discharges.

• Ni-MH battery: Starts lower (around 1.3V) and steadily declines, leading to “low battery” misreadings in voltage-sensitive devices.

》Low-Temperature Performance

During night operations at around 0℃, the trail camera powered by XTAR batteries remained stable without disconnection or power loss.

Some independent reviewers have also tested the discharge performance of the XTAR 1.5V lithium battery in low-temperature environments and compared it with its performance at optimal operating temperatures.

• Red curve: 25°C discharge

• Blue curve: –15°C discharge

At -15℃, XTAR’s discharge capacity decreased from 2796mAh to 2279mAh, retaining over 80% of its performance — an excellent result for lithium batteries in cold environments.

This strong low-temperature performance is attributed to XTAR’s built-in voltage regulation chip, which keeps a consistent 1.5V output and enables stable operation across a wide range of –20°C to 60°C.

Conclusion

Based on the test results, the XTAR 1.5V AA CLR 4300 lithium battery is undoubtedly the ideal replacement for alkaline batteries in trail cameras, with its stable constant-voltage output, long runtime, and outstanding low-temperature performance.

By comparison, Cityork and EBL Ni-MH batteries are more suitable for low-power applications such as remote controls and toys, but struggle to provide reliable power for long-term outdoor monitoring devices.

If you’re looking for a rechargeable AA battery that combines performance, reliability, and long-term value, XTAR is the clear winner.
