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.

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?
