Depends on your device's battery compartment. Check your gear's manual — if it accepts AA/AAA, use XTAR 1.5V Li-ion. If it has a native Li-ion bay (14500/18650/21700), use 3.6V/3.7V cylindrical cells.

LR 3000 = linear discharge with precise meter reading — best for rehearsals, monitoring, and extended sessions where you need accurate battery level indication. CLR 4300 = 1.5V regulated output with a 15-30 minute low-battery warning — ideal for live performance, theater, and broadcast where sudden cutoff is unacceptable.

1.5V provides higher stable voltage for better RF stability and audio performance. Many professional audio devices are designed for alkaline voltage curves (1.5V) and perform suboptimally on 1.2V NiMH cells, especially under load.

RF interference depends on the device's shielding and circuit design. XTAR batteries comply with EMC standards, but we recommend testing on your specific gear. Free evaluation samples are available for qualified professionals.

CLR 4300 maintains constant 1.5V output, then steps down to trigger the device's low-battery indicator — giving you 15-30 minutes to swap batteries before cutoff. No surprise shutdowns mid-performance.

Yes. XTAR 8-slot smart chargers auto-detect chemistry per channel independently. You can charge AA, AAA, 14500, 18650, and 21700 cells simultaneously — each channel optimizes for the specific battery inserted.
