Motorola RLN6351 1100 mAh Li-Ion Battery for RDX 2W Radios

SKU CH-FKRX-SH4ZN

1100 mAh lithium-ion battery delivers up to 12 hours of talk time for Motorola RDX 2 W and CP110 series radios

  • Reliable power for critical communications with Motorola RDX radios
  • Up to 12 hours uninterrupted use from 1100 mAh lithium-ion cell
  • Fits RDX, CP110, RDU and RDV series two-way radios
  • Durable yet lightweight at 16 oz for all-day comfort
  • Rechargeable 1100 mAh capacity extends time between charges

Ready for RDX and CP110 radios

The Motorola RLN6351 is a 1100 mAh lithium-ion battery built for Motorola RDX series 2 W two-way radios and CP110 series models. It supplies the voltage and connector profile those handsets expect, so professional crews and hobby users can swap cells without adapters. The pack is sold new and carries the manufacturer part number 6351.

Twelve-hour shift coverage

Under continuous transmit-receive cycling the cell delivers up to 12 hours of runtime before recharge, matching the rated capacity of 1100 mAh. Voltage remains stable through the discharge curve, preventing the sudden drop-off that cuts range on older chemistries. The lithium-ion construction also resists memory effect, so partial top-ups do not erode future capacity.

Snap-in fit, 16 oz weight

The pack slides into the radio battery rail until the latch clicks, requiring no tools or firmware updates. Alignment ribs prevent reverse insertion, and the 16 oz mass keeps the handset balanced during belt carry. The only common issue is debris in the rail channels; a quick brush-out restores reliable contact.

Questions about this item

How long will the RLN6351 1100 mAh battery power a 2W radio during a full work shift?

The 1100 mAh lithium-ion cell delivers up to 12 hours of continuous use on a single charge, so a full day on site is covered without swapping packs.

Which radios must I already own for the RLN6351 to fit and charge correctly?

It is built for Motorola RDX, CP110, RDU and RDV series two-way radios, so any of those models will accept the battery directly.

Will the 16 oz battery change the balance of my existing RDX handset compared to the original pack?

At 16 oz the RLN6351 matches the standard weight profile for these radios, so handling and belt-clip balance stay the same as with the factory cell.
