Compatible Garmin Nuvi Battery

This Cameron Sino DS-CS-IQN770SL battery replaces the original 010-00657-06 cell in Garmin Nuvi 770 and 770T navigation units. It is built for owners who need a direct-fit lithium-polymer power source for daily driving or fleet use.

Thermals and Power Draw

The 3.7 V, 1250 mAh lithium-polymer cell delivers steady voltage with low internal resistance, so the GPS runs cool during extended trips. Normal use produces no audible noise and draws only the current the device requires.

Build and Daily Use

The slim black pack measures 60.80 x 36.60 x 5.30 mm and slots into the Nuvi battery bay without tools or adapters. Its OEM-compatible connector ensures a secure fit, while the lightweight polymer construction keeps the navigator balanced on the windshield mount.

Questions about this item

How do I install the DS-CS-IQN770SL battery in my Garmin Nuvi 770, and what step do people often miss?

Power off the device, remove the back cover, disconnect the old pack, connect the new 3.7V 1250mAh Li-Polymer cell, then reassemble; the step often missed is fully charging it before first use.

What maintenance or replacement will this 1250mAh GPS battery need later?

The Li-Polymer cell will gradually lose capacity; plan to replace it once runtime drops below your needs, typically after several hundred charge cycles.

What limit appears first during sustained navigation use of this 3.7V battery?

The 1250mAh capacity sets the runtime limit; continuous screen-on navigation will drain the pack until it reaches the low-voltage cutoff.
