Six small silver button cells in a clear blister pack

DUSLAN

DUSLAN 20H 1.2V NiMH Button Battery 6-Pack

SKU CH-WYBV-YRNH4

Six 1.2 V NiMH button cells deliver 20 mAh capacity, recharge up to 1000 cycles and suit solar lights or custom packs

  • Battery Type20H
  • Rechargeable NiMH chemistry eliminates memory effect
  • 2 V nominal voltage suits low-drain devices
  • 20 mAh capacity powers solar lights and custom packs
  • Up to 1000 charge cycles extend usable life
  • 6 mm diameter and 3.1 mm height fit standard 20H holders

Rechargeable 20H button cells

This pack contains six DUSLAN 20H nickel metal hydride button batteries rated at 1.2 volts and 20 mAh each. They suit solar garden lights, remote controls and small custom battery packs that require a compact rechargeable cell.

Simple drop-in replacement

The cells measure 11.6 mm in diameter and 3.1 mm in height so they fit standard 20H holders without soldering. Polarisation is clearly marked; reversing a cell will prevent charging. No memory effect means they can be topped up at any state of charge.

Capacity decides suitability

At 20 mAh these batteries only power very low-drain devices such as solar path lights or memory-backup circuits. They are not for buyers who need higher capacity for digital cameras, toys or any device that draws more than a few milliamps.

Questions about this item

How can I confirm the 1.2 V NiMH 20H cells are delivering their rated 20 mAh capacity after charging?

Charge the cells fully, then apply a 4 mA load until voltage reaches the 1.0 V cut-off; the runtime should reflect the 20 mAh rating.

What comes in the pack and are there any extra items I must buy to use these button cells?

The pack contains six 20H NiMH button cells (11.6 mm diameter, 3.1 mm height, 1.7 g each); no charger or accessories are included.

Which version should I choose if my device lists Varta V20H, IEC 20H or ASC1125 as compatible?

All listed codes — V20H, IEC 20H, ASC1125, H20 BC — refer to the same 20 mAh 1.2 V NiMH button cell, so this 6-pack matches any of them.
