Previous Experiences with Rechargeable AA Batteries
Prior to testing the Xtar Li-ion batteries, I had several disappointing experiences with other rechargeable AA and AAA batteries. Two brands in particular performed terribly, lacking sufficient power to operate my Mini-Z cars. The low power output resulted in flickering lights and the inability to even turn the cars on. This led me to revert to standard nickel-metal hydride (NiMH) batteries for reliability.
These unreliable batteries were not just limited to my Mini-Z cars. I avoided using them in my radio controllers due to the fear of sudden power failure during operation and loss of vehicle control. The lackluster performance ultimately resulted in discarding the faulty batteries and sticking with my dependable NiMH option.
Introducing the Xtar Li-ion AA Batteries and Charger
I was contacted by Xtar to review their Li-ion AA batteries, available on Amazon. The manufacturer sent me a package of AA batteries and a charger. The charger is a Type-C port charger that claims to handle both Li-ion and NiMH batteries, supporting both AA and AAA sizes simultaneously. It also boasts good heat dispersion.
The charger is designed to charge four AA batteries at once, with the capability of adding AAA batteries in a separate compartment. The charging specifications include 5V at 2A and 9V at 2A. The package also included a user manual and charging cable.
Voltage Testing and Comparison
I used a multimeter to measure the voltage of various batteries: brand new alkaline AA, used NiMH AA and AAA, and the new Xtar Li-ion AA batteries. The brand new alkaline AA batteries registered a voltage of around 1.5V, as expected. The NiMH batteries showed slightly lower voltages, around 1.4V, indicating they were partially discharged despite a full charge.
The fully charged Xtar Li-ion AA batteries registered a voltage of approximately 1.54V which is higher than my NiMH batteries, indicating their higher power capacity. The Xtar batteries exhibited slightly higher voltage than expected for 1.5V batteries, potentially causing compatibility issues with some devices.
Real-World Testing and Unexpected Results
I installed the Xtar Li-ion AA batteries in my Mini-Z car and a radio controller to test their performance in real-world scenarios. Initially, the batteries powered the Mini-Z car and radio controller, but only briefly. The car only worked for a short moment.
Further testing revealed that some older electronics might not be compatible with the higher voltage output of the Xtar Li-ion batteries, leading to intermittent operation or complete failure. This was confirmed by testing in multiple devices; they worked in my newer radios perfectly.
Conclusion and Final Thoughts
The Xtar Li-ion AA batteries provide a good charge and high voltage, performing well in newer electronics such as radios and flashlights. The charger is also convenient for its ability to charge both Li-ion and NiMH batteries simultaneously. However, their higher voltage may cause incompatibility issues with older electronics that have voltage cut-off mechanisms.
Overall, the Xtar batteries are a solid option, though compatibility needs to be considered. Their high voltage and capacity make them suitable for many devices, and their excellent performance in the radio and flashlights shows they are worth purchasing if you need higher voltage. The charger's versatility also adds value. Just be aware of potential compatibility issues with older devices.
