Core Performance Advantages

≥500 IEC standard cycles: Assembled from grade‑A WJ‑H‑AA1600 low‑self‑discharge cells, pass IEC61951‑2‑2017 cycle test for standby equipment and portable industrial devices.
10S series 12.0V finished AA battery pack: Factory spot‑welded ten AA‑1600mAh low‑self‑discharge cells, stable 12.0V rated output for standby power and replacement‑device projects.
Strict cell matching process: Capacity, internal‑resistance and open‑circuit voltage sorted before spot‑welding, minimize voltage drift under continuous‑load working conditions.
Low self‑discharge characteristic: Adopt low self‑discharge AA1600mAh cells, maintain good capacity retention for long‑interval standby applications.
Wide working temperature: Discharge range from‑20℃ up to +50℃, fit indoor equipment and mild outdoor operating scenarios.
Flexible OEM options: Custom flying leads, Tamiya/JST/SM/KET connectors, heat‑shrink sleeve wrapping, polarity adjustment and private label printing.
