WEIJIANG original 7.2V AA Ni-MH rechargeable battery pack, rated capacity 2000mAh, assembled with 6 pieces of grade-A 1.2V AA cells in series via precision spot welding, equipped with standard white connector for direct plug-and-play installation.
Featuring low total internal resistance (≤210mΩ), flat discharge platform and ≥450 IEC standard cycles for assembled pack, it delivers reliable and consistent power for medium-power devices. Widely applied in security surveillance systems, portable medical equipment, small power tools, RC models and industrial standby power modules.
All battery packs undergo strict capacity & internal resistance matching before assembly, and 100% performance inspection before delivery. We support full OEM customization including lead wire length, connector type, heat-shrink wrapping and polarity adjustment, with complete international safety certifications for global export.
