Battery Charger For A Modern Car.

I need a battery charger for a 2015 Nissan Qashqai that I can safely use without disconnecting the battery terminals.

I've heard that if I use a standard trickle charger it could fry the ECU or other sensitive electronic components.

Any suggestions ?

Cheers.

Manufacturers (cars, batteries and battery chargers) will always recommend that the battery is disconnected before charging....but it isn't necessary if you use a conditioning trickle charger - the sort that can be left on safely for months at a time. A conventional high-power charger (the sort you'd use to charge a flat battery) really needs the battery isolated from the car's electronics...so you'd need to disconnect.
Oh, and if your car has "stop-start", it has a different sort of battery and needs an even more sophisticated "smart" charger.

Further to the above....the £25 maintenance charger here would be fine UNLESS you have "stop-start"....then it's a lot more (as you can see!)

Thank you both for your sound advice.

My Qashqai does have Stop Start so I've bought a Halfords Smart charger which will do the job. I hope I won't need it but I only do short infrequent journeys.

Cheers.
