Compatible GPS Battery

The CameronSino CS-IQN300SL is a 1250mAh lithium-polymer replacement battery built for Garmin Nuvi 300, 310, 350, 360 and 370 series navigators. It matches the original 3.7V specification and fits the 37.00 x 60.00 x 5.20mm form factor. Buyers who need a different voltage or a larger capacity will not be served by this cell.

Thermals Noise Power

The pack uses a standard Li-Polymer chemistry rated at 3.7V and 1250mAh, so it draws the same current profile as the factory unit during navigation and charging. No active cooling is required and the cell operates silently within the device enclosure. ISO9001, RoHS and CE certifications confirm the materials meet recognised safety and substance restrictions.

Certified Replacement Pack

The battery carries ISO9001, RoHS and CE marks, verifying the production process and the absence of restricted substances. It cross-references Garmin part numbers 010-00538-78, 361-00019-02, 361-00019-06 and IA2B309C4B32, plus the NavGear Streetmate GP-43. No software, tools or additional accessories are included in the package.

Questions about this item

How do I install the CS-IQN300SL battery in my Garmin Nuvi 350 and what step is often missed?

Power off the device, open the battery compartment, disconnect the old pack, connect the new 3.7V 1250mAh Li-Polymer battery ensuring the connector clicks fully into place, then close the cover and charge fully before first use.

What maintenance or replacement will the CS-IQN300SL need over time?

The 1250mAh Li-Polymer cell will gradually lose capacity; expect to replace the battery when run-time drops below your needs, typically after several hundred charge cycles.

What limit appears first during continuous GPS navigation with this battery?

The 1250mAh capacity sets the runtime ceiling; under sustained use the battery will deplete before any thermal or voltage limit is reached.
