CS Cameron Sino Replacement Battery RBP-GM40 3400mAh 3.7V

What it is and who it fits

This Cameron Sino replacement battery delivers 3400 milliamp hours at 3.7 volts for Datalogic Gryphon GM4100, GM4130, GM4400, GM4430, GBT4400, GBT4430 and GM4100-BK-433Mhz barcode scanners. It replaces original part numbers BT-8 and RBP-4000 and matches the factory dimensions of 68.70 by 18.40 by 18.40 millimetres. The pack weighs 21.1 grams and includes a decoded chip that communicates with the scanner exactly like the original cell. Buyers who need a different voltage or a higher capacity will not be served by this model.

What to check before ordering

Verify that your scanner carries one of the listed Gryphon model numbers and that the original battery shows part number BT-8 or RBP-4000. Confirm the physical size matches 68.70 by 18.40 by 18.40 millimetres so the pack seats correctly in the battery compartment. Ensure the connector orientation lines up with the device socket before fitting. A low-quality third-party charger can reduce service life, so use only the manufacturer-approved power supply.

Behaviour under sustained load

The 3400 milliamp hour rating supports extended scanning shifts without a mid-day recharge. Built-in overcharge, over-discharge, over-voltage and short-circuit protection maintains safe operation during continuous use. The supplier notes that a new cell reaches its best runtime after two or three complete charge and discharge cycles. ISO9001, RoHS and CE certifications confirm consistent manufacturing quality for long-term reliability.
