DUSLAN 40H 1.2V NiMH Button Cell 6-Pack

SKU CH-MKY1-QEAKT

Six rechargeable 1.2 V NiMH button cells deliver 40 mAh each and up to 1000 charge cycles for solar lights or custom packs

  • Battery type40H
  • Rechargeable up to 1000 cycles for years of use
  • No memory effect keeps capacity stable over time
  • 40 mAh NiMH chemistry powers solar lights reliably
  • Compact 11.6 mm diameter fits standard button-cell slots
  • Six-cell pack simplifies custom battery-pack builds

DUSLAN 40H NiMH Button Cells (6-Pack)

These rechargeable 1.2 V nickel-metal hydride button cells come in a six-pack for devices that use the 40H form factor. They suit solar garden lights, small electronics and custom battery packs where a compact 11.6 mm diameter cell is required.

Practical limits of the 40H format

Capacity is 40 mAh at 1.2 V, so run-time suits low-drain applications rather than high-current loads. Physical dimensions are 11.6 mm diameter by 5.2 mm height; verify that your device’s compartment matches these measurements before purchase.

Cycle life decides suitability

Each cell delivers 500 to 1000 recharge cycles with no memory effect, providing years of service in daily-charged solar lights. Buyers needing higher capacity per cell or a different voltage should choose another chemistry or form factor.

Questions about this item

Should I pick the 40 mAh cells or the 30 mAh alternative?

The 40 mAh version stores more energy per cell, so solar lights or custom packs run longer between charges.

What does 1.2 V actually deliver in a device?

Each cell provides a steady 1.2 V through most of its discharge curve, matching the voltage profile many low-drain gadgets expect.

Will the IEC 40H designation limit the charger I can use?

IEC 40H defines the physical size and chemistry; any NiMH charger that accepts 11.6 mm diameter button cells will work.
