Four blue cylindrical rechargeable Li-Ion batteries 16340 size 33 x 16.4 mm

Centenex Electronics

Centenex Electronics RCR123a 3.7V Li-Ion 700mAh 4 Pack Blue

SKU CH-YDAJ-T3WWA

Four rechargeable 3.7 V Li-ion cells, 700 mAh each, sized 33 × 16.4 mm for Arlo VMC3030 cameras

  • Product typeBatteries
  • Rechargeable Li-Ion chemistry reduces waste and cost
  • 700 mAh capacity powers Arlo VMC3030 cameras reliably
  • 7 V output matches CR123a and 16340 requirements
  • 33 x 16.4 mm dimensions fit standard battery compartments
  • Four-pack supplies spares for multi-camera setups

Arlo-Ready 3.7 V Li-Ion Cells

These four RCR123a batteries deliver 3.7 V and 700 mAh each in the 16340 form factor. They are built for Netgear Arlo Wire-Free HD security cameras such as the VMC3030 and arrive new in a blue four-pack.

Replaces Disposable CR123a Primaries

The pack substitutes single-use CR123a cells with rechargeable 0.7 Ah Li-Ion units. The jump makes sense for cameras that cycle daily, cutting waste and recurring cost while keeping the same 33 x 16.4 mm footprint.

Check Camera Voltage Tolerance First

Verify that your Arlo model accepts 3.7 V Li-Ion chemistry; some older units expect 3 V primaries and can malfunction. Confirm the battery compartment fits the 16340 dimensions and that your charger supports Li-Ion RCR123a cells.

Questions about this item

What are the exact dimensions of each RCR123a cell so I can confirm they fit my Arlo camera's battery compartment?

Each battery measures 33 mm in length and 16.4 mm in diameter, matching the standard 16340 form factor used by the Arlo VMC3030.

How do I install the four batteries correctly, and what polarity mistake should I avoid?

Insert each cell with the positive button facing the contact marked plus; the blue wrapper helps identify orientation, but reversing even one cell will prevent the camera from powering on.

When should I replace the pack, and what indicates the Li-Ion cells are worn out?

Replace the set when a full charge no longer lasts the usual runtime or the voltage sags below 3.7 V under load; the 700 mAh capacity will gradually fade after many recharge cycles.
