XTAR Launches LR 900 1.5V USB-C Rechargeable AAA Lithium Battery for More Familiar, Predictable Power

XTAR introduces the LR 900, a 1.5V USB-C rechargeable AAA lithium battery with linear discharge for familiar, alkaline-like voltage behavior and clearer low-battery cues.

XTAR today introduces the LR 900, a 1.5V USB-C rechargeable AAA lithium-ion battery designed around a simple idea: rechargeable power does not have to change the way a familiar AAA-powered device behaves.

With a linear discharge profile that gradually decreases as energy is consumed, the LR 900 is designed to more closely follow the voltage behavior of a traditional alkaline AAA battery. Combined with direct USB-C charging, it offers a practical rechargeable option for frequently used, compatible AAA devices where both charging convenience and recognizable low-battery behavior matter.

A Different Approach to Rechargeable AAA Power

Rechargeable 1.5V lithium batteries can offer a useful alternative to disposable alkaline batteries, but they do not all behave the same way during discharge.

Many regulated 1.5V lithium batteries maintain a relatively flat voltage until the battery is close to empty. While this can help maintain consistent device performance, it can also make battery-level detection less intuitive in some devices: an indicator may continue to show a high battery level before the device suddenly shuts down.

The LR 900 takes a different approach.

Its linear discharge profile allows the voltage to decline progressively as the battery is used, more closely resembling the behavior of an alkaline battery. In compatible devices, this can provide a more recognizable low-battery transition and give users a better indication that it is time to recharge.

Designed for Devices That Benefit from Familiar Voltage Behavior

The LR 900 is particularly suited to frequently used, compatible AAA-powered devices with current requirements of up to 0.6A.

For these devices, the goal is not simply to provide rechargeable power. It is to provide power in a way that works naturally with the device’s existing battery expectations.

Everyday devices

Wireless mice, keyboards and presentation clickers can consume AAA batteries regularly. With the LR 900, users can recharge the same batteries instead of repeatedly replacing disposable cells, while its gradual voltage decline can help compatible devices provide a more useful low-battery indication.

Household electronics

Remote controls, digital thermometers and compatible sensors are often used repeatedly but can be easy to overlook when their batteries are running low. The LR 900 provides a reusable power option while retaining a discharge pattern familiar to devices designed around conventional AAA batteries.

Travel and portable use

The built-in USB-C port removes the need to carry a dedicated battery charger for the LR 900. A USB-C power source can be used to recharge the battery, making it practical for users who already carry USB-C charging equipment.

Direct USB-C Charging Without a Dedicated Charger

The LR 900 integrates a USB-C charging port directly into the battery, allowing users to recharge it using a USB-C power source.

A full charge takes approximately 1.5 hours. Its intelligent three-stage charging system manages the charging process, while the battery is designed for 800+ recharge cycles.

For users who regularly rely on AAA batteries, this changes the routine from replacing disposable cells to simply recharging the batteries already in use.

Protection Built Into a Compact AAA Battery

The LR 900 incorporates a built-in safety chip designed to protect against overcharge, over-discharge, short circuit and abnormal temperature conditions.

If over-discharge protection is triggered, automatic reactivation allows the battery to resume charging once connected to a suitable power source.

The LR 900 also features a leak-resistant construction and is designed for operation from -20°C to 60°C.

These features are intended to make the battery suitable for repeated everyday use across a range of compatible environments.

A Rechargeable AAA for Everyday Compatibility

The LR 900 is not designed to make every AAA-powered device behave differently. Instead, its linear discharge profile is designed around the behavior that many conventional AAA-powered devices already expect.

For users looking to move frequently used compatible AAA devices away from disposable batteries without introducing a radically different voltage behavior, the LR 900 combines:

  • 1.5V Rechargeable lithium-ion chemistry
  • Linear discharge More familiar voltage decline
  • Built-in USB-C Direct charging without a dedicated charger
  • 800+ cycles Designed for repeated recharging
  • Approximately 1.5 hours Full charging time
  • Built-in protection Overcharge, over-discharge, short circuit and abnormal temperature protection
  • -20°C to 60°C Operating temperature range
  • Up to 0.6A Compatible device current requirement

The LR 900 expands XTAR’s 1.5V rechargeable battery portfolio with an option focused on familiar device behavior and charging simplicity, rather than simply maximizing output voltage stability or energy capacity.
