1200mAh 3.6V Ni-MH Battery Pack with Custom Cable & Connector – Ideal Power for Cordless Phones & Consumer Devices

For consumer electronic OEM manufacturers and hardware product designers, selecting a stable, safe and cost-effective rechargeable battery is critical to product performance. Nickel-metal hydride (Ni-MH) AA cells remain one of the most trusted power sources for low-to-medium power portable electronics, proven by decades of mass adoption from leading battery brands.

Our 1200mAh 3.6V Ni-MH battery pack is assembled with 3pcs AA 1200mAh NiMH cells in series. We supply both bare AA 1.2V single cells and finished battery packs with custom wires and connectors. Whether you need off-the-shelf standard packs or fully custom OEM assemblies, this Ni-MH solution delivers steady discharge, great safety and eco-friendly performance for your electronic projects.

Ni-MH technology has long replaced older Ni-Cd batteries. It eliminates toxic heavy metals like cadmium and lead, supports hundreds of charge-discharge cycles, and works reliably across a broad temperature range. Compared with lithium cells, NiMH has simpler BOM requirements and higher safety margins, which makes it a preferred choice for many household portable electronics.

This product line consists of AA size nickel-metal hydride rechargeable cells (1.2V,1200mAh) and pre-assembled 3-series battery packs reaching 3.6V.

Each AA cell adopts nickel hydroxide as the positive electrode, hydrogen storage alloy for the negative electrode, alkaline electrolyte and sealed steel casing. When connected in 3S configuration, it forms a compact 3.6V battery pack, wrapped with heat shrink tube and pre-soldered with leads and plugs.

We support flexible customization: series-parallel configuration, wire length, connector types (PH, XH, JST and more), wire color, heat shrink sleeve and custom logo printing. Customers can buy bare individual AA cells or finished battery packs directly according to their device design.

Key Specifications

✅ Cadmium-free & Lead-free, RoHS compliant. Modern NiMH formulation removes memory effect, users do not need to fully drain the battery before recharging.
✅ Full customization service available. We tailor series/parallel layout, wire length, connector types, heat shrink tube and wire color. OEM logo printing is supported.
✅ Stable flat discharge curve. Consistent voltage output, reliable power supply even at low temperature down to -20℃.
✅ Two supply options to match your project stage. Purchase bare single AA cells for your own assembly, or get pre-assembled battery packs with soldered wires and plugs to save production labor.
✅ High safety performance. No risk of thermal runaway, safer than lithium batteries for children’s toys and household devices.

This 3.6V 1200mAh NiMH pack is a drop-in replacement for many legacy consumer electronics, the most classic use case is cordless phone handsets.

1. Cordless Phone Handset【Typical Application】 Old-style and household cordless phone handsets commonly use 3 AA Ni-MH cells connected in series and sealed as a 3.6V pack inside the battery compartment. 1200mAh is a mainstream capacity specification for this device.
2. Electric Toys RC cars, RC boats, and robot toys. The 3.6V output drives motors and control circuits smoothly. Ni-MH is safer than lithium batteries, which is perfect for children’s toy products.
3. Small Emergency Lights / Flashlights Many rechargeable emergency lamps, camping lights and handheld torches adopt this 3.6V NiMH pack paired with simple charging circuits.
4. Shavers & Hair Clippers A large number of rechargeable electric shavers and hair trimmers use built-in 3.6V NiMH battery packs. 1200mAh capacity provides stable continuous runtime.
5. Wireless Mouse / Keyboard / Game Controller Suitable for a small number of 3.6V wireless peripherals. Note that single AA / AAA Ni-MH cells are more widely used for ordinary keyboards and mice.
6. Small Instruments & Meters Multimeters, temperature detectors and portable testing instruments. Some product models select this 3.6V NiMH pack as rechargeable mobile power supply.
7. Solar Lawn Lights / Night Lights Certain solar lamps use 3.6V NiMH packs for energy storage, charging by sunlight during daytime and automatically discharging for lighting at night.

Many OEM buyers struggle between NiMH and Li-ion batteries for consumer electronics. NiMH shines in these scenarios:

• You want simpler charging circuits without complex protection boards.
• Your product targets low cost, mature, proven power solution.
• Safety is top priority, especially children’s toys and household daily devices.
• Your equipment needs wide-temperature performance and long standby life.

Lithium cells deliver higher energy density but add BOM cost and stricter safety testing requirements. For cordless phones, shavers, small toys and emergency lights, AA NiMH 3.6V packs remain a mature, economical and reliable option, which explains why global battery giants still keep NiMH production lines for consumer electronics.

We offer bulk, anti-static and pallet packing for mass orders. OEM bulk orders are welcome. Samples can be provided for customer performance testing before formal bulk production.
