Direct replacement battery

This lithium-ion cell is built for the Magellan Maestro 4200 4210 4220 4250 series and matches the original K4790SA108821 part. It delivers 3.7 volts and 2200 milliampere-hours in a single black pack. The unit is new and 100 percent OEM compatible.

Sustained runtime

The 2.2 ampere-hour capacity supports extended navigation sessions without a sudden voltage drop. Internal chemistry maintains steady output over long drives rather than fading after a short burst. Users can rely on consistent power for route recalculations and screen brightness.

Compact fit and finish

Dimensions of 70.10 by 50.41 by 5.50 millimetres allow the battery to seat cleanly in the device cavity. The slim profile prevents bulging or latch strain during daily insertion and removal. Black housing matches the original aesthetic and resists visible wear.

Questions about this item

How much heat does the 3.7V 2200mAh lithium-ion cell produce during continuous GPS use?

The battery is a standard 3.7V 2200mAh Li-ion pack; it generates only normal warmth during extended navigation and requires no active cooling.

Does the 70.10 x 50.41 x 5.50 mm pack fit my Maestro 4250 without extra tools or adapters?

Yes, the cell matches the original K4790SA108821 dimensions exactly and slots into the Maestro 4200, 4210, 4220 and 4250 battery compartment with no additional hardware.

Will the DS-CS-MR4200SL work alongside the original charging circuit in my older Maestro 4200?

The 3.7V 2200mAh Li-ion chemistry is fully compatible with the factory charging system in all listed Maestro models, so the existing cradle or vehicle charger operates normally.
