Direct Replacement Battery

The CameronSino DS-CS-IQN285SL is a 1250mAh Li-Polymer battery built for the Garmin Nuvi 285, 285W and 285WT. It matches the original ED26ED2985878 part number and delivers 3.7V output. Travellers who rely on those models for daily navigation get a fresh power source without changing devices.

Fits Inside Existing Housing

The pack measures 60.00 x 36.50 x 5.00mm and weighs 60 grams, so it slides into the Nuvi battery compartment without modification. No extra cables, adapters or firmware updates are required. The black casing matches the original look. Users who need a different form factor or higher capacity will not be served by this unit.

Steady Output on Long Drives

Rated at 1250mAh, the cell maintains a stable 3.7V supply during extended routing sessions. Li-Polymer chemistry resists voltage sag better than older chemistries when the screen stays bright and GPS reception fluctuates. It is not designed for rapid charging or high-drain accessories beyond the Nuvi unit itself.
