Cameron Sino 1300mAh Battery for Nintendo 3DS CTR-003

Compatible replacement battery

This 1300mAh lithium-ion pack fits Nintendo 3DS, 2DS XL and Switch Pro Controller models that use part number CTR-003. It delivers 3.7 volts and 4.81Wh in a 53.24 x 38.00 x 6.30mm form factor weighing 27.4g. The built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. ISO9001, RoHS and CE certifications confirm the manufacturing standards.

Upgrading from a worn original

When the factory cell no longer holds a charge through a typical session, this unit restores the original runtime without modifying the console. The decoded chip communicates with the host exactly like the stock battery, so no firmware work is required. The improvement is worthwhile once the original drops below usable capacity after repeated cycles. Swapping takes only a few minutes with common tools.

Check your device before ordering

Verify that your console or controller lists CTR-003 or C/CTR-A-AB on the original battery label. Ensure the compartment accepts the 53.24 x 38.00 x 6.30mm dimensions. Plan for two or three full charge-discharge cycles to reach peak performance. Avoid low-quality third-party chargers and do not expose the pack to temperatures above 60°C or 140°F.
