NiMH Batteries for Power Tools & High-Drain Equipment
Weijiang Power manufactures high-discharge nickel-metal hydride (NiMH) cells and custom battery packs for cordless power tools and high-current equipment, including drills, drivers, saws, sanders, garden tools and vacuum cleaners. Our high-rate Sub-C, SC and C-size cells are engineered for the strong, sustained current that motor-driven loads require.
Why NiMH for power tools: high-rate NiMH cells deliver high continuous and pulse current with low internal resistance, tolerate repeated fast charging, and avoid the memory and heavy-cadmium drawbacks of older NiCd packs. They are also more tolerant of abuse and temperature than many lithium alternatives, making them a durable, cost-effective choice for mid-voltage tool packs.
- High-rate cells: 5C-capable AA / Sub-C series with strong discharge performance for demanding motor loads.
- Custom pack builds:تكوينات مستقيمة ومتوازية للجهود الشائعة — 4.8 و6 و7.2 و9.6 و12 و14.4 و18 و24 فولت — بأطراف ملحومة ومستشعرات حرارة وPCM/BMS وموصل حسب اختيارك.
- Rugged & long-lived:نحو 500–1000 دورة ونطاق حرارة واسع (-20°C حتى قيمة مرتفعة) للورشة والميدان.
- Certified & shippable: CE, RoHS, REACH, MSDS/SDS and UN38.3 documentation for smooth international delivery.

Frequently Asked Questions
Q1: Which pack voltages are common for cordless power tools?Tool packs are built in 4.8 V, 6 V, 7.2 V, 9.6 V, 12 V, 14.4 V, 18 V and 24 V configurations, in stick or side-by-side layouts.
Q2: Can NiMH packs replace older NiCd tool batteries?Yes. Both chemistries use 1.2 V cells, so a correctly matched NiMH pack is a direct, higher-capacity replacement with no memory effect and no toxic cadmium.
Q3: What discharge rate can high-rate tool cells deliver?Our high-rate AA and Sub-C cells are built for high continuous and pulse current (around 5C-class loads) with low internal resistance for drills, drivers and saws.
Q4: What protection and connector options are available?Packs can include welded tabs, NTC temperature sensors, PCM/BMS protection and your specified connector and housing.
Q5: Which certifications are provided and what is the MOQ?CE, RoHS, REACH, MSDS/SDS and UN38.3 documentation is available for shipping. Custom pack MOQ is flexible; share your voltage, cell count and current needs for a quote within 24 hours.
