XTAR introduces the new C-size CLR 7200, bringing regulated 1.5V power,rechargeable lithium-ion technology, and convenient USB-C charging to C-powered devices

XTAR has expanded its 1.5V rechargeable lithium battery lineup with the launch of the new C-size CLR 7200 USB-C lithium battery.

Designed for devices that use C-size batteries, the CLR 7200 combines 1.5V regulated output, 4350mAh capacity, 7200mWh energy, and built-in USB-C charging in a rechargeable C-size format.

The launch extends XTAR's 1.5V rechargeable lithium battery technology to a larger battery format, giving users an alternative to conventional disposable C batteries and 1.2V NiMH rechargeable batteries.

A New 1.5V Rechargeable Solution for C-Size Devices

C-size batteries continue to power a wide range of household electronics, lighting equipment, portable devices, and other products that require more energy than typical AA-powered equipment.

For rechargeable users, however, there has traditionally been a trade-off.

Alkaline C batteries provide the familiar 1.5V output but are disposable. NiMH C batteries can be recharged repeatedly, but their nominal voltage is typically around 1.2V.

For some devices designed around 1.5V batteries, this voltage difference can affect battery-level detection or operating performance.

Community discussions reflect this real-world need. In one Reddit discussion, a user reported that 1.2V NiMH batteries caused a C-powered pet door to remain in low-battery mode and specifically looked for a rechargeable C battery with a 1.5V output.

The CLR 7200 is designed to address this particular gap: a rechargeable C-size battery that provides regulated 1.5V power.

Stable 1.5V Output with a Gradual Discharge Profile

The core of the CLR 7200 is its regulated 1.5V output.

Unlike conventional NiMH rechargeable batteries, which start at a higher voltage and gradually decline throughout discharge, the CLR 7200 is designed to maintain a stable 1.5V output through most of its usable capacity.

This can provide a more consistent power supply for C-powered devices designed around conventional 1.5V batteries.

The CLR 7200 also uses a gradual linear discharge profile toward the end of its cycle rather than maintaining regulated output until an abrupt shutdown.

This approach is intended to provide a more predictable transition as the battery approaches depletion.

4350mAh Capacity and 7200mWh of Energy

The CLR 7200 is rated at 4350mAh and 7200mWh, providing a substantial energy reserve for C-powered devices.

For regulated 1.5V lithium batteries, looking at energy in watt-hours alongside mAh can provide a clearer picture of the available energy. The battery's internal lithium-ion cell operates at a higher voltage, while the integrated electronics regulate the output to approximately 1.5V.

For this reason, XTAR specifies both capacity and energy rather than relying on an mAh figure alone.

USB-C Charging Without a Dedicated C-Cell Charger

The CLR 7200 is equipped with a built-in USB-C charging port, allowing the battery to be recharged directly with a USB-C cable.

This eliminates the need for a dedicated C-size battery charger and makes the battery easier to recharge at home, while traveling, or when using portable power sources.

A USB wall charger, power bank, laptop, or other compatible USB power source can be used for charging.

USB-C charging makes the battery particularly convenient for users who regularly move between home, outdoor, and travel environments.

Designed for Everyday C-Powered Devices

The CLR 7200 is designed for equipment that continues to rely on the C-size battery format.

Potential applications include:

The key consideration is not simply whether a device accepts a C battery, but whether it is compatible with a regulated 1.5V rechargeable lithium battery.

Real-World Testing: Performance Beyond the Spec Sheet

Battery specifications provide an important starting point, but actual capacity, voltage behavior, and thermal performance are what ultimately determine how a rechargeable battery performs in use.

Following the launch of the CLR 7200, independent testing has provided an early look at its performance.

In a third-party test using a battery analyzer, the CLR 7200 delivered a measured capacity close to its rated 4350mAh capacity across multiple discharge conditions. The test also reported an open-circuit voltage of approximately 1.50–1.52V.

Thermal behavior was also evaluated under different discharge loads, providing additional data on the battery's performance under higher current conditions.
