SKU CH-HDY0-VJMR1

A 3.6 V lithium-ion cell replaces CR123A disposables in compatible cameras and devices, delivering 650 mAh with no memory effect

  • Battery typeCR123
  • Rechargeable lithium-ion cell eliminates disposable battery waste
  • 6 V nominal voltage with 4.2 V peak for compatible devices
  • 650 mAh capacity delivers long-lasting power per charge
  • No memory effect allows flexible recharging at any level
  • Direct replacement for CR123A primaries in most cameras

What this battery is

The DUSLAN RCR123A is a 3.6V lithium-ion rechargeable cell in the 16340 form factor. It delivers a 650mAh capacity and serves as a reusable alternative to disposable CR123A primaries for compatible devices. Users who need a direct drop-in for equipment designed around the lower voltage of primary lithium cells should verify suitability first.

Build and daily handling

The cell uses standard lithium-ion chemistry with no memory effect, so partial recharges do not reduce usable capacity over time. Its CR123A dimensions allow it to fit existing battery compartments without adapters or sleeve modifications. Peak voltage reaches 4.2V, which is higher than the nominal 3V of primary CR123A batteries and can affect sensitive electronics.

Voltage limits in practice

The 4.2V peak output means the battery is not suitable for certain flashlights and cameras that rely on the stricter voltage profile of primary lithium chemistry. Devices with tight voltage tolerances may malfunction or sustain damage if powered by this cell. Buyers who need guaranteed compatibility with every CR123A host should choose primary disposables instead.

Questions about this item

What voltage does the 3.6 V RCR123A reach at peak charge?

The cell peaks at 4.2 V when fully charged, so devices must tolerate that higher voltage.

What physical size must the battery compartment accept?

It uses the CR123A / 16340 form factor, so the compartment must fit that diameter and length.

How should the cell be inserted the first time?

Observe the correct polarity; the positive button goes to the device’s positive contact to avoid damage.
