New to AA Lithium?
Start smart with the XTAR LR 2000
Curious about switching to rechargeable lithium batteries but unsure where to start?
The LR 2000 offers the perfect introduction. It delivers the same output performance, USB-C charging, and 1200 recharge cycles as our best-selling 1.5V lithium battery LR 3000 — at a more accessible price.
Its discharge curve closely simulates that of standard alkaline batteries, making it fully compatible with common low to medium drain devices like smart home, audio-visual equipment, wireless keyboards, and toys.
Whether you’re a first-time user, a budget-conscious buyer, or simple wants to try the new tech before committing to a higher capacity, the LR 2000 offers an affordable and reliable way to make the switch from disposable batteries.
Affordable for Everyone
It makes advanced lithium technology accessible at a lower cost while maintaining high performance and quality.

More Stable & Higher Power, Better Than Alkaline
Alkaline batteries start high voltage but drop off quickly. The LR 2000 mimics their discharge curve while maintaining a higher and steadier average voltage throughout.
It stays in the optimal voltage range longer, meaning fewer battery changes and less risk of early shutdowns, keeping your devices run smoothly from start to finish.
USB-C Charging, Smarter Than It Looks
No extra charger needed, the built-in smart charging circuit manages the entire process automatically — saving cost and less to worry about.
Supports charging via USB-C to USB-C or USB-A to USB-C cables.In addition, the matching cable features a new design that effectively prevents short circuits caused by accidental battery contact.
Fast charging in just 2.5
hour.
3-stage smart charging to extend battery life.
Auto-activates and begins charging
upon plugging in
if over-discharged.
1200 Recharge Cycles, More Use & Less Waste
With up to 1200 cycles to replace thousands of single-use Alkaline batteries. Cost is recovered in just a few uses, every additional cycle is money saved and less waste.
True AA Size, No Squeezing
The battery’s length and diameter are carefully controlled to fit AA battery compartments without forcing or modification. Unlike many USB-C AA batteries are slightly too long, causing installation issues in everyday devices.
Protected Inside, No Worry Outside
These batteries go into devices you use every day, so we made them safer.
🔒Leak-Proof Design
Prevents corrosion in high- use household devices, protects your gear and keeps your home safer.
🛡️Protection Circuit
Guards against overcharge, over-discharge, and short circuits to safeguard both battery and device.
⚙️Cell Construction
Durable materials and internal pressure relief ensure long- term reliability and peace of mind.
Works Well in Cold and Heat
Performs reliably from -20°C to 60°C , far beyond the comfort zone of Alkaline batteries, maintaining stable power output at all times.
Made for Everyday Power Needs
Confidently replace alkaline cells in your AA-powered devices, enjoying smarter, longer-lasting, sustainable power.
