Replacement Battery for Retevis RB48 and RB648
This nickel-zinc battery replaces the original BL48 and BL648 packs in Retevis RB48 and RB648 two-way radios. It delivers 2400mAh capacity at 3.7 volts and weighs 40.0g. The cell measures 59.60 x 36.20 x 9.30mm to fit the existing battery compartment.
Fully Decoded Chip and Protective Packaging
A fully decoded chip makes the pack behave like the original battery, so the radio reads charge level correctly. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. The box includes shock-absorbing foam to protect the cell during transit.
Simple Swap with Break-In Cycles
Installation is a direct swap: remove the old pack, align the connector and press the new battery into place. Online videos show the procedure if needed. The cell reaches full performance after two or three complete charge and discharge cycles. Users who need a different voltage or connector type should look elsewhere.

Questions about this item
How many charge cycles before the nickel-zinc 2400mAh cell needs replacing?
The nickel-zinc chemistry typically delivers several hundred full cycles; after 2 or 3 initial cycles the pack reaches its rated 2400mAh capacity and then gradually declines.
What stops the 3.7V pack first during a long transmission — voltage sag or the protection circuit?
The built-in over-discharge and over-voltage protection will cut power before the 3.70V cell drops too low, so the protection circuit is the first limit.
Does the 40g pack get hot or make noise when the radio runs all day?
The battery itself is silent and only warms slightly under normal load; excessive heat suggests a charger or radio fault, not the cell.
