Compatible Replacement Battery

This lithium-ion pack replaces the original BL18 cell in Retevis RT18 and RT618 two-way radios. It delivers 1000 mAh at 3.7 V and matches the factory dimensions of 53.40 x 34.00 x 5.60 mm. A built-in protection circuit guards against overcharge, over-discharge and short circuits. The pack weighs 22.0 g and is supplied new with ISO9001, RoHS and CE certification.

Suitable Users and Limitations

Radio operators who need a direct drop-in spare for the BL18 will find this pack fits and functions without modification. It is not intended for devices that require a different voltage, capacity or physical footprint. Buyers who want more storage or a higher voltage should look at something else. The battery is also unsuitable for any radio model not listed as compatible.

Capacity and Runtime Headroom

The 1000 mAh rating provides enough energy for typical shift-length voice communication on the supported handsets. Heavy transmit duty cycles or extended standby periods will drain the cell faster and may require a mid-day recharge. Runtime scales with transmit power setting and squelch activity, so very high-power operation will reach the limit sooner.

Questions about this item

Which Retevis two-way radios accept the FYIOGXG 1000mAh 3.7V pack?

The battery fits the Retevis RT18 and RT618 models that use the original BL18 part number.

Will the replacement pack charge in the existing desktop charger supplied with my RT18?

Yes, the new fully decoded chip works just like the original so the stock charger recognises and charges it normally.

How can I confirm the battery is performing correctly after the first few charge cycles?

After two or three full charge and discharge cycles the pack should reach its rated 1000mAh capacity and power the radio for the expected talk time.
