DUSLAN RCR123A 16340 3.7V 700mAh standard battery

SKU CH-J70A-7J73A

A 3.7 V lithium-ion RCR123A cell delivering 700 mAh to replace disposable CR123A batteries in compatible devices

  • Battery typeCR123
  • Delivers 3.7V for devices needing higher voltage
  • 700 mAh capacity powers gear for longer stretches
  • Lithium-ion chemistry means no memory effect
  • Recharges repeatedly to replace disposable CR123A cells
  • 16340 form factor fits standard CR123A slots

What this battery does

The DUSLAN RCR123A is a 3.7V 700mAh lithium-ion cell sized to the 16340 form factor. It fits devices that accept CR123A dimensions and provides rechargeable power for compatible cameras and electronics.

Behaviour under load

The lithium-ion chemistry delivers a steady 3.7V output without the voltage drop common in primary cells during sustained use. No memory effect means the 700mAh capacity remains reliable across repeated charge cycles, though the higher voltage makes it unsuitable for certain flashlights and cameras designed for 3V primaries.

Installing and common issues

Installation is a direct swap into any CR123A battery compartment, requiring no adapters or tools. The main issue arises when users ignore the voltage difference: devices built strictly for 3V disposable lithium cells can malfunction or suffer damage, so checking the equipment manual before fitting is essential.

Questions about this item

How much heat does the 3.7 V RCR123A generate during continuous use?

Lithium-ion chemistry produces minimal heat at the 700 mAh discharge rate, so the cell stays close to ambient temperature in typical camera or flashlight duty.

What charger is required before the 16340 cell can be used?

A dedicated 3.7 V lithium-ion charger with a 16340 / RCR123A slot is needed; standard CR123A primary batteries are not rechargeable and cannot charge this cell.

Will the higher 3.7 V output damage a device designed for 3 V CR123A primaries?

The supplier notes the cell can replace CR123A primaries in most devices, but certain flashlights and cameras may not tolerate the higher voltage.
