Capacity and Voltage Match

The single specification that decides fit is the 4200mAh capacity at 7.40 volts, matching the original AK17463-005 and CT17102-2 part numbers. The physical dimensions of 92.50 x 73.16 x 27.40 mm must align with the printer's battery bay. ISO9001, RoHS and CE certifications confirm the cell meets recognised safety and environmental standards.

Integration Into a Printer

The battery slides into the printer's existing compartment and connects through the original connector. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuit. No extra hardware or adapter is required for installation. Users who need a higher capacity than 4200mAh or a different voltage will not be served by this pack.

Questions about this item

How long will the 4200mAh capacity run a compatible portable printer?

The 4200mAh rating at 7.40V delivers 31.08Wh, matching the original specification for L405, RW420 and RW420 EQ printers so runtime equals the factory battery when new.

What connector standard does the replacement battery use and what does it limit?

The pack uses the same fully decoded chip and connector as the original AK17463-005 and CT17102-2 batteries, limiting compatibility to the listed printer models only.

Will the 92.50 x 73.16 x 27.40 mm pack fit my printer's battery bay?

Those exact dimensions and 245.0g weight replicate the OEM battery, so it seats in the L405, RW420 and RW420 EQ compartments without modification.
