Battery, starter and electrical repair in Montréal
In deep cold, a battery loses much of its capacity exactly when the engine needs it most. We test the battery, starter and alternator together, because a new battery fixes nothing if the alternator isn't charging it.

Parasitic drains
A battery that dies overnight often hides a module that won't go to sleep. We measure the resting draw and isolate the circuit responsible.
Quality parts
Batteries suited to Québec's climate and to your vehicle, including AGM batteries for start-stop vehicles, with battery registration when the vehicle requires it.

Frequently asked questions
How long does a battery last?
About four to six years in Québec, sometimes less with lots of short trips. We recommend testing every fall after year three.
My car started with a boost, do I need a new battery?
Not necessarily. A test shows whether the battery is worn out or just discharged.
Do you fix lighting and accessory problems?
Yes: headlights, power windows, locks, sensors. We follow the wiring diagram to the cause.
